Pulverized Fuel Boiler - an overview | ScienceDirect Topics
Although stoker systems and fluidized-bed combustion units use relatively coarse-crushed coal, most coal combustion at the present time takes place in pulverized-fuel boilers. One of the objectives of the pulverizer coal in such systems is to reduce the coal particle size so that 70–80% passes through a 200 mesh (75 μm) screen (summary after Scott, 1995).

Technology comparison of CFB versus pulverized-fuel firing for …
Fluidized Bed Boilers Versus Pulverized Fuel Boilers The choice of technology of Fluidized Bed Combustion (FBC) Boilers over the conventional Pulverized Fuel (PF) Boilers has several reasons. FBC boilers can handle a wide range of fuels with low heating values (as low as 1500 kcal/kg), high ash content (as high as 55 per cent) and high sulphur content.

Mitsubishi Power, Ltd. | Pulverizers
A pulverizer (coal pulverizer) is installed for this purpose, and pulverizes pieces of coal several centimeters in diameter down to fine particles. The pulverizer includes pulverization, drying and classification functions. The classification function plays the important role of ensuring that only fine particles are sent to the boiler.
