PA Fans, ID Fans, Draught Fans, FD Fans, SA Fans in

Jan 10, 2017 · In power plants, the PA fans supply air for conveying of the pulverized coal from coal mills to the furnace area. These primary air fans produce a high pressure to push the coal and air mixture through pulverizer into the furnace. The most common configuration of the draught fans used as a PA fan is the backward curved centrifugal fan.

Pulverizer Wikipedia

Similar to the ring and ball mill, the vertical spindle roller mill uses large "tires" to crush the coal. These mills are usually found in utility plants. Raw coal is gravityfed through a central feed pipe to the grinding table where it flows outwardly by centrifugal action and is ground between the rollers and table.

Local steam temperature imbalances of coalfired boilers

Due to an unfavourable coal mills configuration, the local temperatures in the combustion chamber can differ. This can affect the temperatures in two parallel steam lines so much that even a shutdown of the entire system would be necessary. The modelling and subsequent simulation of the plant is a proven way to identify problems and to show
