Coal Preparation Systems for Boilers
Depending on the characteristics of the coal and the particular boiler application, the designer may chose pulverized coal (PC) firing, cyclone firing, stoker, or fluidized bed firing methods. Whatever method is applied, raw coal should be prepared before being fed into the furnace.

Coal Pulverizers
Raw coal is fed to pulverizer from the coal feeder via a center feed pipe. The coal is grounded between the three grinding rollers and the rotating table in the pulverizer. Pulverized coal is simultaneously dried by the drying gas fed from bottom part of pulverizer and carried into the separator fixed at the top of pulverizer.

Pulverised Coal Combustion
Pulverized coal (PC) combustion is presently the system of choice for coal-fired power-generating plants. In PC combustion, the coal is dried and is ground to a specified fineness, with a maximum particle size of 250–300 μm, depending on the reactivity of the coal.

Improving Coal Pulverizer Performance and Reliability
Pulverization is currently the favored method of preparing coal for burning. Mechanically pulverizing coal into a fine powder enables it to be burned like a gas, thus allowing more efficient combustion. Transported by an air or an air/gas mixture, pulverized coal can be introduced directly into the boiler for combustion.

Grinding and combustion characteristics of woody biomass for co-firing
One is co-firing where wood powder and pulverised coal are injected into the boiler furnace from the same burner. In most cases, raw fuels are fed together into the mill and ground fuels are transported together to the burner. This method is called "co-firing of mixed fuels" hereafter. Another way is in-furnace co-firing, which is ...

Grinding and combustion characteristics of woody biomass for co-firing
Tamura et al. [10] evaluated the co-firing characteristics of alternative fuels with pulverised coal and also researched the coal blending characteristics [11]. The following results were obtained. The volatile release profile of woody biomass with pulverised coal was additive and predictable while the char burnout behaviour was non-additive.
