Influence of coal type on devolatilization and combustion in fluidized beds

Journal Article:

Abstract

Devolatilization and burnout times have been measured for twelve different fuels in a glass combustor. Fuel sizes varied from 250 MUm up to 8 mm and results are reported for bed temperatures in the range 775-1010C. Devolatilization could last for up to one minute and times were dependent upon coal type, temperature and particle size. The burnout times showed that the combustion process was not controlled by diffusion alone (except for a very reactive lignite), and that surface reaction rates and ash diffusion were significant.
