Uses For Pulverizing Coal

Pulverised Coal an overview ScienceDirect Topics

Pulverized coal is used in many utility boilers. Due to the small particle size, pulverized coal can be transported pneumatically. Coal particles contain four major components: moisture, volatiles, char, and ash. When heated, the moisture is dried and the volatiles are devolatized.

Pulverized coal-fired boiler

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 furnacefor the combustion of solid fuels. Coal is ground to the size of a fine grain, mixed with air and burned in the flu
