Pulverised Coal - an overview | ScienceDirect Topics

Pulverized coal combustion includes wall-fired, tangentially fired, arch-fired, and roof-fired systems. Wall-fired and tangentially fired systems are the most common type of boilers. PC firing uses pulverizers to grind the fuel to particle sizes of typically >70% passing through 200 mesh or 74 μm [33] .

Pulverised Coal - an overview | ScienceDirect Topics

A cyclone-fired boiler uses large crushed coal particles (typically 4 mesh size), which must be burned at a slower rate than PC 1 to complete the combustion process. This slower rate of combustion requires a unique burner design. 2 The burner's assembly is a long, round chamber (6- to 10-ft. diameter) formed by water wall tubes attached to the outside of the boiler…
