PPT PERFORMANCE ANALYSIS OF COAL MILLS PowerPoint

There are basically four different types of pulverizing mills which are designed to reduce coal with a top particle size of about 50 mm to the particle size range necessary for fairly complete combustion in a modern pulverized coal fired boiler. Each type has a different grinding mechanism and different operating characteristics.

What are the types of coal? USGS

There are four major types (or “ranks”) of coal. Rank refers to steps in a slow, natural process called “coalification,” during which buried plant matter changes into an ever denser, drier, more carbon rich, and harder material. The four ranks are:

Coal mill pulverizer in thermal power plants

Nov 17, 2012 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. The pulverized coal and air mixture is then transport to the boiler burner
