  • What is the use of a PA fan in a thermal power plant? Quora

    Primary Air Fans are used to lift the pulverized coal from mill to boiler in a power plantFurther, the air from PA Fan is preheated using air preheaters so that the fluidity of coal flow can be maintained in coal pipes and also preheat the coal tIn 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 In power plants the PA fans play an important role inPA Fans, ID Fans, Draught Fans, FD Fans, SA Fans in
