Pulverized Fuel Boilers Pulverized coal boilers fire finely powdered coal, typically with an average particle size of about 25 µm (0.001 in). Coal burns in suspension, like the combustion in an oil- or gas-fired boiler. Coal is pulverized in some type of large mill Pulverized coal is fired out into the furnace

Excess Air. A boiler's excess air supply provides for safe operation above stoichiometric conditions. A typical burner is usually set up with 10-20% excess air (2-4% O2). NOx controls that require higher excess air levels can result in fuel being used to heat the air rather than transferring it to usable energy.

Fossil Fuel Fired Boiler Water-Steam System

Coal-fired units require ignition with either oil or gas, and many are designed to fire oil or natural gas as a backup fuel. Excess air is necessary for proper combustion, but too much can be detrimental to the performance of the combustion system.
