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). Pulverizing is accomplished in

Pulverised Coal an overview ScienceDirect Topics

It is predominantly adopted in large coal-fired utility boilers. The finer the grinding of coal, the more efficient its combustion. The total time required from entry of a coal particle to a furnace to combustion of the particle is very short. This time, however, is dependent on various factors. The heart of a pulverized coal-fired boiler is the pulverizer, also known as the mill. Depending on
