Pulverizer - Wikipedia

The pulverised fuel continues its journey towards the coal burners for combustion. The coarse particles rejected in the classifier are returned to the mill for another cycle of grinding. In order to avoid excess sweeping of coal from the mill, only part of the primary air, directly proportional to the boiler load demand, is passed through the mill.

Cofiring is achieved in these systems through different methods, but the principles of combustion are similar. In wall firing, the fuel is mixed with combustion air in individual burners. Coal is pulverized in the coal mill to a very fine particle size. The coal and primary air are then introduced to the coal nozzle.
