type crushers have choke points, but this does not necessarily mean that choking is likely to occur. Choking — Stoppage of the flow of material through the crusher, usually the result of wet and sticky material clogging exit points. Circulating Load — The amount of oversize returned to the crusher from a screen in a closed-circuit system.
Pulverized coal boilers fire finely powdered coal, typically with an average particle size of about 25 µm (0.001 in). Coal burns in suspension, like the combustion in an oil- or gas-fired boiler. Coal is pulverized in some type of large mill Pulverized coal is fired out into the furnace volume using burners that look somewhat like oil

Coal is composed primarily ofcarbon and hydrogen, but all coal also contains some mineral mat ter (for example, clays, shales, quartz, and calcite); the percentage varies by coal type and source. Coal ash is the mineral maner that is collected after the coal is combusted, along with some un burned carbon.
As shown in Figure 2, coal and preheated primary air first enter the crusher section. Here the coal is im- pacted on a grid section by swing hammers, reducing the coal to a nominal 1/4" size. Drying of the coal also occurs in this section. After the coal passes through the grid section, it enters the two-stage pulverizing sec- tion.
