In essence, the performance of a pulverizer is a delicate balancing act between the hgi, fuel fineness, and throughput. 1. a typical mps89 pulverizer found in many coalfired power plants.

Coal continues to be an indispensable fuel for power plants as it is so cheap and plentiful, but because of coals high environmental impact, implementing and expanding measures to reduce co 2 is an urgent task. methods of reducing co 2 from pulverized coalfired power plants can be roughly categorized into ① reducing fuel consumption.

Coal is first fed from silos at the plant to coal mill pulverizers, which grinds the coal to a fine powder. a fan forces a flow of blended primary ambient air and preheated air into the coal mill where the air and coal powder are mixed to provide combustion air to a furnace, heating water in a boiler which produces steam to drive power.
