Pulverized coal-fired boiler Wikipedia

A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal 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. Coal is ground to the size of a fine grain, mixed with air and burned in the flue gas flow. Biomass and other materials can also be added to the mixture. Coal

Pulverizer Fire and Explosions

All efforts must be taken to prevent coal from accumulating or settling in any of the pulverizer components. Dry coal that is allowed to remain in the pulverizer system can spontaneously ignite. Raw coal to the pulverizer must be uninterrupted and controllable. Precise feeder control and minimal stoppages above and below the feeder are crucial.
