Pulverized coal-fired boiler - Wikipedia

A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.

A modelling study of SOFC coupled with steam and dry coal gasification indicated that the DC-SOFC system is capable of power densities >1.0 W/cm 2 with H 2 O (steam) recycle, and power densities ranging from 0.2 to 0.4 W/cm 2 with CO 2 recycle. This result also suggests that the DC-SOFC system performs better with steam than with CO 2 gasification.
