Bench scale fluidized bed combustor

Abstract EN

A Fluidized bed combustor (FBC) is designed and set-up to investigate the combustion processes of sub-bituminous Egyptian coal particles and wood.

The effect of changing the coal particles size on the values of : (a) gas temperature, (b) heat flux to the combustor wall, (c) radiant-convective overall heat transfer coefficient and (d) combustion level of coal particles are investigated.

The highest combustion level is found to be for coal particles size of 17mm.

The heat transfer coefficient in the case of coal combustion is extremely greater by 500 % than that of wood combustion.
