Full textAbstract:
India is the second largest in major sugar producing countries after Brazil. Bagasse is the fibrous residue of sugar cane after crushing and extraction of juice. Sugar cane bagasse ash is the waste product of the combustion of bagasse for energy in sugar factories. Sugar cane bagasse ash is disposed of in landfills and is now becoming an environmental burden. In this experimental study concrete cubes, beams and cylinders of M20 grade were casted and tested to examine various properties of concrete like workability, compressive strength, split tensile strength, modulus of elasticity and flexural strength. Sugar cane bagasse ash was partially replaced with cement at 2, 4, 6, 8 and 10 % by weight of cement in concrete. After mixing, concrete specimens were casted and subsequently all test specimens were cured in water at 7, 14 and 28 Days. From the results we can conclude that optimum amount of sugar cane bagasse ash that can be replaced with cement is 6% by weight without any admixture.

In Brazil, due to its availability, sugar cane bagasse has a high potential for power generation. The knowledge of ignition behavior, as well as the knowledge of the chemical kinetics, in of fuels combustion process is important features in boilers projects and in the stability of the combustion process control. The aim of this study is to investigate the thermal behavior of sugar cane bagasse, coal and their blends. The methodology proposed by Tognotti et al. (1985) was applied to determine the ignition temperature for all samples. Ignition temperatures were 256oC for neat bagasse and 427oC for neat coal, and 275oC for both blends (50-50% and 25-75%). The Model-Free Kinetics was applied to determine the apparent activation energy (Eα) of the thermal decomposition of sugar cane bagasse. For the two major events of mass loss of bagasse which correspond to the thermal decomposition of organic matter (mainly hemicellulose, cellulose and lignin), average values of Eα were obtained for both combustion and pyrolysis processes. In synthetic air atmosphere, the Eα were 170.8±26.3 kJ⋅mol-1 and 277.8±58.6 kJ⋅mol-1, while in nitrogen atmosphere, the Eα were 185.0 ± 11.4 kJ⋅mol-1 and 82.1±44.4 kJ⋅mol-1. The results obtained can be explained by synergistic effects when both bagasse and coal were blended, changing the fuel reactivity.

The environmental impact of cement production increased significantly in the previous years. For each ton of cement produced, approximately a ton of carbon dioxide is emitted in decarbonation (50%), clinker furnace combustion (40%), raw materials transport (5%), and electricity (5%). Green strategies have been advanced to reduce it, adding natural or waste materials to substitute components or reinforce the mortar, like fibers or ashes. Sugar cane bagasse ash is a by-product generated from sugar boilers and alcohol factories with capacity to be used in concrete production. Composed mainly of silica, it can be used as mortar and concrete mineral admixture, providing great economic and environmental advantages, particularly in regions with sugar culture and industrial transformation like Brazil. In this research, a study of partial substitution of Portland cement by sugar cane bagasse (SCB) is analyzed, in order to reduce clinker in concrete volume, responsible for high emission of CO2 to the atmosphere. An experimental campaign with cementitious pastes was carried out to evaluate the durability properties’ changes due to SCB ash use. Samples containing 15% of sugarcane bagasse ash unveiled good results in terms of durability, indicating that concrete structure with sugar cane ash research is a new and important scientific topic to be highlighted.

Renewable energies have been considered as alternative, clean, available, and ecological sources of energy. The production of biochar from biomass by thermochemical means is considered an efficient method of converting biomass for energy production. In this study, the biochars were produced from the biomasses of peanut shells and sugar cane bagasse at different pyrolysis temperatures (400°C, 450°C, and 500°C). The biomass samples and their produced biochars were characterized using calorific value, Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy and energy dispersive X-ray spectrometry (SEM and EDX), compressibility index, and combustion behavior in order to analyze their potential. Experimental results showed that biochar has better fuel qualities compared to raw biomass. We also found that increasing the pyrolysis temperature clearly improved the calorific value, the morphology, the porosity of the biochars as well as the compressibility index of the biochars. The interest of this study was to produce renewable biochar from peanut shell waste and sugar cane bagasse for use as solid fuel.

Full textAbstract:
Sugar cane bagasse, a biomass material that is readily available, has been used as a fuel for well over 4 decades. However, combustion of bagasse has its own special set of problems which appear to be due largely to the high moisture content of the fuel. In this present research work, in order to gain insight into the effect of moisture on the flame front, an experimental program is carried out on an operating, industrial size bagasse-fired furnace. The furnace is modeled by the three-dimensional CFD package FLUENT. The results of modeling show a considerable delay to ignition due to the drying of fuel. The effect of fuel moisture on drying and heating up of the fuel is the key feature for the investigation done in this work.

The promotion of ecological and renewable materials is gaining more and more interest. Some authors even maintain that the use of plant biomass helps to protect the environment, without giving any supporting values. The aim of this study is firstly to show how much carbon dioxide is saved by not burning sugar cane bagasse (SCB). Secondly, it highlights the structural advantages of using sugarcane bagasse in construction. To do this, we collected the carbon composition of sugarcane bagasse from the literature and evaluated the amount of carbon dioxide emitted during combustion using the carbon-to-carbon dioxide conversion equation. We then formulated an F0 control mortar. Volume fractions of this control mortar are replaced by sugarcane bagasse. For 0%, 3% and 6% rates of sugarcane bagasse, we obtained F0, F3 and F6 respectively.
 The results of this study show that the use of sugarcane bagasse in the mortar makes it possible to lighten the loads on the structural elements while improving the flexural strength of the mortar for a rate of 3% of sugarcane bagasse. In addition, the combustion equation shows that, in the best-case scenario, one kilogram of burnt sugarcane bagasse releases 1.77 kg of carbon dioxide. Using mortar reinforced with sugarcane bagasse therefore helps to reduce greenhouse gas emissions. These mortars can also be used as infill elements such as joists.

A concerted effort has been underway to identify novel solutions that will supplant the use of fossil fuels, the combustion of which has been identified as a primary contributor to greenhouse gas emissions. The objective of this paper is to analyze Mozambican public policies regarding the dissemination of the sugar cane sector and its contribution to the national energy matrix. The analysis revealed that the prominent sugar companies, namely Maragra, Xinavane, Chemba, Marromeu, and Mafambisse, collectively produced 2,737,556 tons of sugar cane during the 2019/2020 harvest season, cultivated across an expanse of 47,351 hectares. Regarding sugarcane production, the country possesses the capacity to yield 766,516 tons of bagasse, which has the potential to generate approximately 331,135 megawatt-hours (MWh) per annum. This would be sufficient to supply 689,864 inhabitants per hour. However, the prevailing public policies in Mozambique's energy sector currently do not mandate the sale or supply of surplus energy produced by industries to the national electricity grid.

Cyclones are not classified as effective devices for removing fine particles, while high efficiency wet scrubbers usually have high operational costs. In order to achieve better performance, the aim of this study is to evaluate, for the first time, a cyclone scrubber design based on the dimensions of a Stairmand cyclone separator with the inclusion of liquid injection nozzles located in different positions to improve the separation of fine particles. Given the lack of studies considering the effect of liquid injection and other operational conditions in the removal performance of a cyclone scrubber with Stairmand dimensions, the present paper provides a complete evaluation of these effects for the separation of sugar cane bagasse ash from air. The parameters investigated were inlet gas velocity, liquid injection position, liquid-to-gas flow ratio and droplet size distribution. The cyclone scrubber performance was evaluated considering collection efficiency and pressure drop. Overall efficiency of almost 99% and low-pressure drop was achieved by employing a liquid-to-gas flow ratio of 0.43 L/m? for the collection of ash from the combustion of sugar cane bagasse. Grade efficiencies revealed that injecting droplets into cyclones significantly improved the removal of fine particles with an aerodynamic diameter less than 2.5 ?m.

Full textAbstract:
This work compares biomass gasification and conventional direct combustion in steam boilers for producing power in the context of Brazilian sugar cane mills. The objective of this technical report is to show that gasification could be a more attractive way to convert biomass in energy, compared to using steam boilers, which in some cases can show a low efficiency. The idea is to use the gasifiers in sugarcane mills that have low pressure boilers (21 to 42 kgf/cm2) that are currently dedicated only to generate steam or electrical power for the mill own energy consumption. The results shows that gasification could be a cost-effective alternative for power production in Brazilian sugar cane plants with some additional advantages like the bagasse usage between the season and off-season periods to maintain a constant power generation throughout the entire year, higher energy availability and efficiency. However, nowadays in Brazil the economic advantage of gasification depends highly on political support and reliable long-term stable political framework conditions with an enough timeframe for the development, construction and operation of biomass gasification plants.

The paper reports on the assessment of the use of bagasse for cogeneration purposes at Hippo Valley Estates (HVE), a sugar manufacturing company in Zimbabwe. Much emphasis was on an assessment of the quantity of energy that was lost due to inefficient combustion of bagasse and the use of steam that was generated. The study investigated the quantity of sugar cane processed and the possible corresponding steam produced; the sugarcane processed was found to be approximately 2.33 million tons per annum and the steam produced was 193.1 tons per hour. The steam was used in the process department as well as to drive mills. The excess steam generated was found to be 81.03 tons per hour. Economic analysis on the use of excess steam to produce extra power for sale to the utility company was also undertaken. It was established that the power plant for the company could generate an annual surplus of US2.8Million as revenue, and the payback period was found to be 3.3 years. The sensitivity analysis of the project indicated that the electricity prices as well as the energy produced were the most sensitive areas in the project. The other inputs such as operations and maintenance costs, interest, capital investment and number of years were not as sensitive as the price and the energy.

Abstract Today the request for save energy and addressing emissions has become a primary concern for every country aiming to achieve sustainable development while preserving its environment. The demand for energy is steadily rising, driven by rapid population growth and industrial development. Fossil fuels continue to play a major role in fulfilling these energy needs., but their combustion is linked to rising environmental issues. There are many sources of energy use to solve the environmental problems and fossil fuel shorted such as biomass. This paper aims to explore the potential of biomass to provide significantly higher amounts of useful energy while reducing pollutant emissions compared to fossil fuels. In this research the two samples of sugar cane bagasse and sawdust is study by slow pyrolysis. Two samples are presented—one from Kenana bagasse and the other from sawdust. Bio-oil is a product of the slow pyrolysis process, and its calorific value, determined through laboratory analysis, is significantly high compared to previous studies. This indicates that bio-oil emits fewer pollutants than fossil fuels, making it suitable for use in transportation and various industrial sectors.

Full textAbstract:
The abundance of bagasse waste from sugar cane processing needs special attention apart from being used for direct combustion in boilers. Sugarcane bagasse waste can be further processed by pyrolysis so that it will produce bio-oil, bio-gas and char products which have the potential to be used as fuel or high-value chemicals. Pyrolysis of bagasse was carried out to study the effect of temperature and the ratio of the amount of Ni catalyst on the yield and composition of bio-oil in the form of oxygen to carbon (O/C) ratio, hydrogen to carbon (H/C) ratio, higher heating value (HHV), content of oxygenated compounds and range of aromatic compounds. Pyrolysis of bagasse is carried out in a fixed bed reactor with a heating rate of 10-12 ºC/minute to the desired temperature. Pyrolysis with and without a catalyst was carried out at a temperature range of 300-600 ºC with a variation of Ni catalyst weighing 2.5 grams and 5 grams. Liquid product analysis was tested using GCMS (Gas Chromatography and Mass Spectroscopy) to determine the compound content in the liquid product resulting from pyrolysis of sugarcane bagasse. Bio-oil resulting from pyrolysis of sugarcane bagasse contains several dominant compounds including alcohol, fatty acids, esters, carotenoids and levoglucosan. However, the yield of sugarcane bagasse bio-oil without catalyst was dominated by high levoglucosan, namely 70.52%. Meanwhile, the bio oil resulting from pyrolysis which varied with 2.5 grams and 5 grams of Ni catalyst was dominated by esters, namely 69.07% and 81.68% respectively. These compounds have different chemical properties and applications, and understanding the composition of bio-oil can help in deciding how to use it efficiently.

Abstract Biomass contains energy used as solid fuel so that biomass will have high added value. Directly combustion of biomass has caused environmental pollution problems. Agricultural and plant estate plantation biomass waste that is widely spread in Indonesia needs to be utilized. The research was aimed at designing and producing biomass pellets for a pilot-scale capacity of 200 kg/hour. The biomass used consisted of empty oil palm fruit bunches (OPEFB), oil palm shells (OPS), cocopeat, corn cobs, and sugar cane bagasse. Pellets are formed by pressing biomass powder with high pressure using a 10 hp pelletizer. The quality of pellets produced was tested based on the standard DIN 53731. The performance test of pelletizing machinery showed that such types of machinery could be produced for 150-200 kg/hour. The test results showed that almost all quality parameters of biomass pellet (moisture content, calorific value, ash content, density, length, and diameter) met the requirements. Synthetic gas produced from burning biomass pellets in the gasifier and stove is able to use for drying and heating for 80 minutes. Pelletizing can enhance the volumetric and calorific value, reduce the transport and storage costs, reduce the moisture content, and improve the handling characteristics of biomass.

Full textAbstract:
The comprehensive CFD models have been used to represent and study the heterogeneous combustion of biomass. In the present work, the operation of a global flue gas circuit in the sugarcane bagasse combustion, from wind boxes below primary air grate supply, passing by bagasse insertion in swirl burners and boiler furnace, to boiler bank outlet is simulated. It uses five different meshes representing each part of this system located in sequence: wind boxes and grate, boiler furnace, swirl burners, superheaters and boiler bank. The model considers turbulence using standard k-ε, combustion using EDM, radiation heat transfer using DTM with 16 ray directions and bagasse particle tracking represented by Schiller- Naumann model. The results showed good agreement with expected behavior found in literature and equipment design. The more detailed results view in separated parts of flue gas system allows observing some flow behaviors that cannot be represented by usual simplifications like bagasse supply under homogeneous axial and rotational vectors and others that can be represented using new considerations like the representation of 26 thousand grate orifices by 144 rectangular inlets.

Full textAbstract:
A comprehensive CFD model is developed to represent heterogeneous combustion and two burner designs of supply sugar-cane bagasse into a furnace. The objective of this work is to compare the insertion and burning of a Brazilian south-eastern sugar-cane bagasse using a new swirl burner design against an actual geometry under operation. The new design allows control the particles penetration and scattering inside furnace by adjustment of axial/tangential contributions of air feed without change their mass flow. The model considers turbulence using RNG k-, combustion using EDM, radiation heat transfer using DTM with 16 ray directions and bagasse particle tracking represented by Schiller-Naumann model. The obtained results are favorable to use of new design swirl burner because its axial/tangential control promotes more penetration or more scattering than actual design and allows reproduce the actual design operation without change the overall mass flow supply.

In the White Crystal Sugar processing industry from sugar cane plants, the boiler is the main station in the steam production process. The steam produced by the boiler is used for the sugar making process and also as a turbine driver for power plants. In the steam production process, PT GMM-BULOG Blora utilizes dregs from the sugar cane milking process or called bagasse to be used as boiler fuel. So the boiler is called Bagasse Boiler. In this study, an analysis of the efficiency of the PT GMM-BULOG Blora bagasse boiler was carried out to determine the actual performance of the bagasse boiler during operation during the 2024 sugar cane grinding season. The method used for this analysis is Direct Method Efficiency. In this direct method, the analysis is carried out by directly comparing the energy produced by the boiler with the amount of energy required for the combustion process. With the direct method, this study collected data including: steam capacity, steam temperature, feed water pressure, feed water temperature, amount of fuel, and fuel calorific value. From this study, the results of the analysis of the efficiency of the PT GMM-BULOG Blora bagasse boiler using the direct method were 61.1%, with an average consumption of bagasse fuel of 15.02 tons/hour, and an average steam production of 45.9 tons/hour. These results indicate that the bagasse boiler is working inefficiently because the standard efficiency of the bagasse boiler based on the boiler specifications from the manufacturer is 84.6% with the amount of steam produced being 60 tons/hour.

Full textAbstract:
Sugar cane bagasse ash (SBCA) is a fibrous waste-product of the sugar refining industry. It is generated as a combustion by-product from boilers of sugar and alcohol factories. This is composed mainly by silica and this by-product can be used as a mineral admixture in mortar and concrete. This waste product is already causing serious environmental pollution which calls for urgent ways of handling the waste. On the other hand, the boost in construction activities in the country created shortage in most of concrete making materials especially cement, resulting in an increase in price. This study examined the potential use of sugarcane bagasse ash as a partial cement replacement material. In this paper, Bagasse ash has been chemically and physically characterized, in order to evaluate the possibility of their use into concrete.

Full textAbstract:
Concerns have been raised that many sugarcane varieties in the development pipeline, particularly in the Central and Southern regions of Australia, have fiber quality classified as soft, with some soft enough to cause processing problems in the factory. The main issues have been feeding off the cane through the milling train and high bagasse moisture contents, causing subsequent combustion issues and low steam pressure at the boiler station. These cane varieties are usually designated as ‘soft-canes’, and their presence had been noted for at least 60 years. An attractive trait is their relatively high sugar yield per hectare. Some other general characteristics have been reported as often (but not always) having relatively low fiber content and being easier to prepare by the shredder, resulting in a larger number of smaller sized particles in the prepared cane. During the development of new cane varieties, Sugar Research Australia carries out tests for ‘fiber quality’. Experiments were carried out at Isis Central Mill to understand and improve the processing of existing soft-cane varieties. During the 2019 crushing season, a pilot-scale shredder was used to simulate the effect of shredder settings (speed and grid setting) that are known to affect preparation levels. Four existing soft-cane varieties (SRA1A, SRA4A, SRA11A and QN04-1643) were tested, along with Q208A that provided a reference as a middle-of-the-range variety (perceived to be neither a soft nor hard cane). The prepared cane produced was tested for fiber quality at the SRA fiber quality laboratory in Bundaberg. As measured at the factory, the preparation level and two physical properties (compression and permeability) were identified as important for the milling process. All the cane varieties responded similarly to speed and grid setting, with the soft-canes being part of a continuum, not a separate subset. The overall conclusion was that adjusting shredder speed and grid setting can control preparation and potentially address feeding problems at the milling train through improved control strategies.

El azúcar en México ha sido el principal y único producto comercial obtenido de la caña de azúcar (Saccharum officinarum) desde su introducción en el siglo XVI. De su procesamiento tecnológico se obtienen coproductos y subproductos (sacarosa, etanol, bagazo, residuos de cosecha cañera, melazas, lodo de filtros o cachaza, vinazas y cenizas de combustión), los cuales tienen gran potencial como materias primas en diversos procesos extractivos, químicos o biotecnológicos en un proceso de diversificación productiva. Sin embargo, la diversificación, la competitividad y el establecimiento de biorrefinerías de la industria azucarera es compleja, y se ve limitada por la productividad del cultivo, derivada a su vez de condiciones biofísicas y socioeconómicas y de la participación de múltiples actores con diferentes objetivos, estrategias y percepciones. Muchos trabajos han demostrado el potencial de la industria como biorrefinería (producción combinada de azucares, etanol y cogeneración eléctrica). Sin embargo, pocos estudios a nivel regional se han focalizado, a través de la integración de indicadores productivos, socioeconómicos y ambientales, a determinar qué zonas de abasto cañero tienen la potencialidad, en función de su aptitud edafoclimática y los recursos y capacidades de las unidades productivas, de expandir la productividad regional sin el incremento de la frontera agrícola para la producción de azúcar, etanol y otros derivados. Mexican Sugar Cane Bio-refining in the Twenty-first CenturySince its introduction in the sixteenth century, the only commercial product obtained from sugar cane (Saccharum officinarum) has been sugar in Mexico. As a means of diversification, the by-products obtained during processing (sucrose, ethanol, bagasse, sugarcane crop residues, molasses, filter mud, vinasse combustion and ashes) have great potential as raw materials in several chemical or biotechnology industries. However, establishing bio refineries, and embracing these alternative products while maintaining competitiveness is no simple task. It is limited by crop productivity, biophysical and socioeconomic conditions, and the problem of incorporating multiple stakeholders with different objectives, strategies and perceptions. Many analysts have demonstrated the potential of the industry and bio-refining (mixed production of sugars, ethanol and power cogeneration); but few regional studies have integrated production, socioeconomic, and environmental factors in such a way as to determine which sugar cane zones have the potential (in terms of their edaphoclimatic characteristics y the resources and abilities of the economic units) to expand local productivity without increasing the agricultural frontier in order to produce sugar, ethanol and other derivatives.

To meet the growing energy needs of the world’s population, international governments have turned to biomass energy from agricultural waste as a form of renewable energy. To this end, this study is based on the experimental and practical determination of certain physicochemical properties of three agricultural residues (cocoa cortex, oil palm fibres and sugar cane bagasse) using approximate and structural analysis methods. Then, using a METERK electronic detector, the small quantities of CO2 emitted during combustion in 0.5 g boilers of each of these waste products used to produce energy (heat and/or electricity) were determined. The gross and net calorific values of these biomasses were also determined. Here are some of the results obtained for these three agricultural residues: variable moisture content (from 3.6% to 43.12%), variable organic matter content (from 76.12% to 90.31%), cellulose content (from 32.74% to 55.91%), lignin content (from 8.26% to 27.05%), variable net calorific values (from 6.581 kWh/kg to 10.461 kWh/kg) and low CO2 gas emissions (from 439 ppm to 447 ppm). This proves that these three agricultural residues are very good potential sources of energy that can be used as fuel in boilers to produce large quantities of heat that can be converted into electricity by turbines connected to alternators using electromagnetic induction phenomena. Finally, this work provides credible information for public and private decision-makers in the field of electricity production from the combustion of these agricultural residues in boilers.
