Streszczenie:

Conversion of biomass into gas suitable for further exploitation is one of the valuable renewable energy pathways due to the wide distribution and availability of raw materials. Biomass gasification is a thermochemical process of partial combustion in a reduced oxygen environment that aims to produce hydrogen-enriched syngas. Updraft gasifier design, with its advantages of high efficiency, produces syngas with higher hydrogen yield compared to other gasifier designs. The main drawback of the updraft gasifier is high yield of tars in the outflow gas decreasing its lower heating value. Recently,

Biomass gasifiers are equipment’s that can generate producer gas which is a renewable, alternate source of energy that can be employed for power generation and thermal applications. In this experimental study the gasifier is tested in updraft and downdraft modes and performance analysis was carried out. For both the studies, casuarina wood and ambient air were used as feed stock and gasification agent respectively. From the experimental analysis it was inferred that the performance of the biomass gasifier was higher in downdraft mode than updraft mode.

Several research has investigated and operated different types of gasifiers, with updraft gasifiers being a widely used variant. However, this type of gasifier faces a significant challenge due to the high tar content in the produced gas. The issue arises because tar produced in the pyrolysis zone exits the reactor directly without decomposition, which typically occurs at high temperatures. Therefore, this research aimed to modify the updraft gasifier and conduct initial tests to evaluate the new characteristics. The main modification was carried out by moving the gas outlet from the top to th

Abstract Nowadays, the consumption of non-renewable energy is high. As a result, the availability of this energy is decreasing. Because of this, other energy alternatives are needed. One example of another option is the use of biomass. An example of using biomass is the gasification process. This process was carried out in a device called a gasification stove, namely a gasifier. A gasifier has been developed to produce an optimal combustion system. The constraints in this development are costs for manufacture and the potential for failure. Therefore, simulations using Ansys Computational Fluid

In this paper, numerical investigation and optimization is conducted upon an improved updraft gasifier which is expected to overcome the weakness of conventional updraft gasifier. The comprehensive Aspen Plus model of the improved updraft gasifier is based on the RYield and RCSTR reactor. The tar prediction model is constructed, and the yield of tar is determined by the volatile of biomass and gasification temperature. The Aspen Plus simulation results agree very well with experiment results for the product yields and gasification efficiency, which shows the accuracy of the Aspen Plus model. T

Biomass, the world's largest renewable energy source, will continue to grow in the following energy markets. As a result, small biomass conversion systems are more competitive than large stand-alone converters because most of the biomass sources have low energy density and are widely distributed in space. The current study offers a small solid biomass power generation system to examine the possibility of direct connection of updates fixed bed gasifiers and a Stirling engine. The fixed bed updraft gasifier uses a combustion burner built into the gasifier to completely burn the synthetic gas pro

Most of the thermodynamic modeling of gasification for updraft gasifier uses one process of decomposition (decomposition of fuel). In the present study, a thermodynamic model which uses two processes of decomposition (decomposition of fuel and char) is used. The model is implemented in modification of updraft gasifier with external recirculation of pyrolysis gas to the combustion zone and the gas flowing out from the side stream (reduction zone) in the updraft gasifier. The goal of the model obtains the influences of amount of recirculation pyrolysis gas fraction to combustion zone on combusti

This work presents the development of an updraft biomass gasifier stove which has been shown to apply the use of biomass fuels for the production of combustible gases. The updraft biomass gasifier stove designed was modified in order to ease the disposal of ashes, which is subsequently constructed using locally available material resources. The gasifier applies the principles of updraft producer gas flows, whereby the stove utilizes rice husk as it useable fuel. The modified gasifier stove was experimentally tested using rice husk as fuel, which was selected base

Energy plays a significant role in a country’s development. Usage of an improved stove that produces biochar could help to reduce the pressure of deforestation, amend soil productivity, and provide cleaner technology for cooking. In Kwale, a county located on the south coast of Kenya, firewood is still used as the primary cooking fuel followed by charcoal. This research aims to investigate the improvements for a Top-litUpDraft (TLUD) biochar-producing gasifier stove, which the users aspired through co-designing.

Biomass is an important source of energy and the most important fuel worldwide after coal, oil and natural gas. Biomass does not add carbon dioxide to the atmosphere as it absorbs the same amount of carbon in growing as it releases when consumed as a fuel. Its advantage is that it can be used to generate electricity with the same equipment or power plants that are now burning fossil fuels. However, the low energy density of the biomass requires developments and advances in conversion technologies in order to increase process efficiency and reduce pollution.
