Introduction. Power generation industry studies have shown that pulverized coal power plants are an area where improved equipment reliability is essential. The Electric Research Institute (EPRI) has determined that 1% of plant availability is lost on average due to pulverizer-related problems.

Pulverized coal power plants are broken down into four categories, with operating temperatures and pressures as a function of the steam temperature and pressure: •. Subcritical pulverized coal (SubCPC) plants, below the critical point of water (540°C and 170–220 bar), have an operating efficiency <38%. •.

2.Coal pulverizer/mill system One of the critical power plant components that is relied upon to convert the energy stored in coal into electricity is the coal pulverizer or mill. The coal flow is controlled by the feeder, allowing coal to flow into the pulverizer mill.

In power plants, PA fans supply air for conveying of the pulverized coal from coal mills to the furnace area. These fans produce pressure upstream of the pulverizer, to push the coal and air mixture through the pulverizer into the furnace. Backward Curved Centrifugal Fan is the most common centrifugal fan used as a PA fan in a boiler power plant.
