  • Types of Boiler Coal PulverizersBright Hub Engineering

    Thermal 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.
