mill at coal-fired power plant in Malaysia. Coal flow distribution were sampled from the vertical straight PC pipes just after the pulverizer by using Dirty air pitot (DAP) and Pulverized Fuel Sampler (PFS) to measure the flow velocity and extract coal samples [8]. To ensure isokinetic sampling, the sampling gas velocity is maintained at the

Pulverizer Performance & Capacity Improvements

Clean air balancing is an integral part of fuel line air-to-fuel ratio balancing. Establish similar system resistance for each coal line on a balanced air flow basis. Provide a correlation between fuel line "dirty air" and clean air velocities. Ensure the minimum fuel line velocity is maintained after optimization of primary air flow.

Pulverizer Wikipedia

A control circuit monitors the coal level in the mill, and controls the speed of the raw coal feeder to maintain it. Maintaining the coal level in the mill offers a built-in capacity cushion of pulverized fuel to take care of short interruptions in the raw coal circuit. The mill is pressurized and the air-tightness is ensured by plenum chambers
