Pulverised Coal - an overview | ScienceDirect Topics

Pulverized coal firing is the method of choice for large industrial boilers (e.g., > 250,000 lb steam/h) and coal-fired electric utility generators since pulverized coal-fired units can be constructed to very large sizes (i.e., up to ≈ 1300 MW or ≈ 9.5 million lb steam/h) and unlike stoker units, where some designs have coal restrictions ...

Previously, sulfur transformation in pulverized coal combustion between air-fired conditions and oxy-fuel conditions was mainly studied at atmospheric pressure. According to Croiset [34], the net conversion of fuel-S to SO 2 in the flue gas was reduced from 91% in air-fired combustion to 64% in oxy-fuel combustion with recycled flue gas.

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.
