Pulverized Fuel Firing of Boiler | Electrical4U
On the other hand, the pulverized fuel firing system is universally accepted method of boiler firing in the modern age, mainly because it increases the thermal efficiency of solid fuel to a great extent. In the pulverized fuel firing system, we make the coal in fine particles with the help of grinding mills.
