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. The volatile vapor mixes with oxygen and the mixture burns.
