Abstract:

Fluidized bed combustion (FBC) ash from the combustion of high-sulphur fuels with limestone addition can contain from 15 to 25% quick lime content. This excess calcium oxide gives the ash numerous undesirable properties such as strong exothermicity on wetting and high-pH leachate that must be treated before discharge. It also leads to the formation of ettringite with significant deleterious expansion in the landfill. In consequence, carbonation of FBC ash is desirable in order to reduce its alkalinity and improve its disposal characteristics. The current technique to reduce the exothermic char

Abstract:

The thermodynamic behaviours in a PFBC combustor were simulated for the ash from all of the six coals with sand and limestone as bed material. Ash components determined the ash thermodynamic behaviour at high temperature, and each component had different effects. For assessment of the potential for bed material agglomeration, the temperature at which 15% of the ash would become liquid (T15) was calculated with the coal ash, the cyclone ash and the cyclone ash mixed with varying amounts of limestone. Both the bed ash and fly ash, collected from an industrial PFBC plant, consisted of limestone/l

Abstract:

Abstract Biomass, such as wood, binds CO2 as it grows, and is thus considered an environmentally friendly alternative fuel to replace coal. In Finland, biomass is typically co-combusted with peat, and also municipal waste is becoming more common as a fuel for power plants. Wood, peat and waste-based fuels are typically burned in fluidized bed combustion (FBC) boilers. Ash is the inorganic, incombustible residue resulting from combustion. The annual production of biomass and peat ash in Finland is 600 000 tonnes, and this amount is likely to increase in the future, since the use of coal for ene

Abstract:

As a carbon neutral and renewable source of energy, biomass carries a high potential to help sustain the future energy demand. The co-firing of coal and biomass mixtures is an alternative fuel route for the existing coal based reactors. The main challenges associated with co-firing involves proper understanding of the co-firing behavior of blended coal-biomass fuels, and proper understanding of advanced gasification systems used for converting such blended fuels to energy. The pyrolysis and combustion behavior of coal-biomass mixtures was quantified by devising laboratory experiments and math

Heat transfer in circulating fluidized beds was studied in both a 7.3 m high, 152 x 152 mm square, pilot-scale combustor and a 9.3 m high, 152 mm ID transparent cold model unit. Results were obtained for particles of mean size 171-299 µm at superficial gas velocities from 4 to 9.5 m/s and for solids circulation rates up to 70 kg/m².s. For the combustor, results obtained by using membrane walls and a vertical tube as heat transfer surfaces show a strong influence of the cross-sectional area-averaged suspension density on time-averaged, length-averaged suspension-to-surface heat transfer coeffic

Abstract:

Abstract Circulating Fluidized Bed (CFB) boilers are widely used for multi-fuel combustion of waste and bio-fuels. When several non-homogeneous fuels, having varying heat values, are burned simultaneously, the boiler control system can be affected by various control challenges, especially since it is not feasible to reliably measure the energy content of the multi-fuel flow. In order to fulfill energy production needs and maintain the ability to burn low grade fuels, co-firing with high heat value fuels such as gas, oil or coal is needed.

This arrangement is depend on the amount of heat released in each section of the combustor, including bubbling zone and freeboard zones. In addition, heat release rate is defined as the amount of heat released in each section of the combustor. Heat release rate can be calculated from the oxygen consumption of each section per total oxygen consumption. The purpose of this study is to investigate the relationship between in-bed heat release rate and fuel properties, such as particle

Abstract:

碩士<br>中原大學<br>化學工程研究所<br>86<br>In order to understand the combustion phenomena within a vortexing fluidized bed combustor(VFBC), an investigation is carried out in a 0.45m I.D. and 5m height pilot scale VFBC. Rice husk is used as the feeding material. Silica sand serves as the bed material. The effects of various parameters on the combustion efficiency and CO emissions are investigated. Defluidization phenomena caused by burning rice husk is also studied. Experimental results show that the concentration of CO emission increases with primary air and excess air,but decreases with the air rati
