Wood ash, which is recognized as an environmental pollutant, is tried as a new material for CO2 capture in this work. Five wood ash samples obtained from different raw materials were chosen, and an experimental demonstration of the CO2 capture performances of these wood ash samples was present...

Single coal particle ignition behavior was studied in a two-dimensional (200mm×20mm×400mm) fluidized bed under O2/N2 and O2/CO2 atmosphere with O2 volume concentration in the range of 0–40%, by a combination of visual observation of the volatile flame and measurement of the particle center...

Coal sludge is a by-product of coal washing, whose production is huge. Burning it in Circulating Fluidized Bed (CFB) boiler can both recover the heat and reduce the pollution. However, the combustion performances of CFB boilers burning coal sludge are generally not high because the particle size...

During oxy-coal combustion process, limestone desulfurization may change from indirect into direct sulfation due to the high partial pressure of CO2. When the wet flue gas is recycled, the water vapor will also be enriched in the furnace and affect the desulfurization reactions. In the paper,...

This paper reports the results of an investigation into the practical and economic viability of an integrated combined heating and cooling system in a supermarket. This system consists of a direct-drive screw compressor, which is powered by a throttle controlled gas engine. The waste heat from...

In recent years, it has become standard practice to consider Combined Heat-and-Power (CHP) systems for commercial buildings. CHP schemes are used, because they are an efficient means of power generation. Unlike conventional power stations, they produce electricity locally and thus minimise the...
