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).

Circulating Fluidized Bed Combustion - an overview | …

For a bed burning bituminous coal, the carbon content of the bed is only 1%, while the rest of the bed is made up of ash, together with sand and/or lime and calcium sulphate. Because of the small particle size and recycling of solids back to the combustor, the CFBC boiler is able to achieve a combustion efficiency over 98% and a Ca/S ratio of 2.5 for 90% sulfur capture ( Figure 5.11 ).
