mill coal fineness produced and to calculate pulverizer performance We perform isokinetic coal sampling after the dirty air velocity probe traverses are completed This is done to match the sampling extraction velocity with the actual coal particle velocities in the coal pipThermal power plants use different types of coal pulverizers The method used is attrition impact or a combination of both This article explains the characteristics of the three main types attrition impact and attrition and impact or hammer Selection of the type of pulverizer depends on the grindability of the coal the capital costs and maintenance costs and considerations for licensing

The presence of combustible materials in the pulverizer is usually the largest contributor to pulverizer fir In most cases pulverizer fires begin in the under bowl area of the pulverizer that is a very hot environment with an abundance of air Accumulations of debris or coal anywhere in the pulverizer will increase the chance of a mill fireA pulverized coal fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup that is blown into the firebox The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels
