  • Pulverized coal-fired boilerWikipedia

    A 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. 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.
