Another type of larger cyclonic separator shown in figure 5.2c is often used after wet scrubbers to trap particulate matter entrained in water droplets. In this type, the air enters tangentially at the bottom, forming vertex. Large water droplets are forced against the walls and are removed the air stream.

The calculated gas residence time varies in different designs from 1.4-1.7 seconds in systems with a separate precalciner vessel, to 4-5 seconds in extended-duct systems. Some precal-ciner designs induce a swirling or cyclonic motion to the gas stream within the precalciner vessel, which gives the solids significantly longer residence time.

The coal is feed into the coal mill through a central inlet pipe where gravity is used to lead the coal to the bottom of the mill, where the grinding table and some heavy rollers pulverizes the coal to particles. The primary air flow to the furnace is fed through the mill, with the purpose of heating and lift the coal particles out of the mill ...

at the entrance to the coal nozzle, redistributes the coal particles entering the pulverized coal burner to break up the coal "rope" that develops in any typical coal piping system. Coal ropes can contribute to high CO emissions and high flyash UBC by presenting too dense a coal stream to the combustion field.
