preparation pulverized coal

Pulverized coal-fired boiler - WikipediaA 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.preparation pulverized coal,17 Coal PreparationCoal preparation. Pulverizers. Unit 17. Pulverized coal system. 1.
