Pulverized Fuel - an overview | ScienceDirect Topics

Boiler Types. Traditionally, solid fuels are burned in centimeter-size particles in grate-fired stokers or milled to a powder of < 100 μm for combustion in pulverized fuel (PF) boilers. At present, stokers are less common, whereas PF is the dominant boiler type, especially in electric utilities.

Pulverized fuel boilers have good fuel flexibility, but there are limitations too. • Normal hard coals are ground to powder and fired. They will burn as long as there is — Adequate VM to overcome the cooling effect of the moisture to provide ignition — Flame temperature high enough to sustain combustion

SAACKE Firing Plants for Pulverized Fuels

Although pulverized fuels represent a very profitable alternative to natural gas or fuel oil, they have not attracted widespread attention. This is especially unfortunate if dust accumulates as by-products in industrial processes and could be directly utilized to replace valuable (and expensive) standard fuels.

Depending on speed pulverizers are classified as low-speed, medium-speed, and high-speed mills. Pulverized coal burners may be located on the front or opposed walls or in the corners of the furnace. There are two types of fuel-firing systems: bin system and direct-firing system. Coal feeders are either the volumetric or gravimetric type.
