Pulverized Fuel Boilers Pulverized coal boilers fire finely powdered coal, typically with an average particle size of about 25 µm ( in). Coal burns in suspension, like the combustion in an oil or gasfired boiler. Coal is pulverized in some type of large mill Pulverized coal is fired out into the furnace
The Babcock Wilcox Company Steam 41 / Coal Pulverization 131 Chapter 13 Coal Pulverization The development and growth of coal pulverization closely parallels the development of pulverized coalfiring technology. Early systems used ballandtube mills to grind coal and holding bins to temporarily store the coal before firing.
coal is pulverized and dried. Dryer coal is easier to pulverize, and less mill power is needed to achieve the same coal fineness. Additionally, with less fuel moisture, more complete drying of coal can be achieved in the mill. This results in increased mill exit temperature (the temperature of the coal and primary air mixture at mill exit ...
