What is pf fired boiler?

For getting better efficiency from boiler, coal is pulverized in mills (powder form)

before entering into boiler along with hot air. This is done in order to control

damage to boiler tubes and plates due to high (but cheap) sulphur content

in coal. These types of boiler are usually called super critical boiler and

works on high pressure (3600psi) and temperature (610 degree C)

unlike sub critical boilers.
