Beater wheel mills are designed to prepare a coal powder air-fuel mixture for combustion in furnace chambers of coal-freed power plants by coal drying, pulverizing, classifying and transport. Their multipurpose function usually results in operation instability accompanied by unacceptable vibration. This usually is a significant problem due to unplanned shutdowns. Beater wheel mill maintenance ...

The classification function plays the important role of ensuring that only fine particles of the pulverized coal are sent to the boiler. Within a rotating-type classifier, fine particles are passed through while coarse particles are eliminated by utilizing the relative balance of centrifugal force and centripetal force produced by a blade rotating at several dozen rpm and the flow of air. MHI ...

The fineness of the coal powder and the uniformity of the coal flow sent to the burners are crucial parameters to achieve an effective combustion in coal-fired power plants. Coal pulverisers or coal mills are the heart of a PCF boiler. Often, the root causes of non-optimised combustion lie with the pulverisers. Capacity, reliability, and environmental issues such as slagging, fouling, and ...
