For a given coal, at least drying and proper grinding (with regard to the combustion technology used) can help to minimize UC content in ash, . Optimisation of coal mills using a dynamic classifier can help to solve this problem . As for the operating conditions, the type of the combustion technology is a fundamental factor.

4. Pulverized fuel Fired Boilers (PF Fired B) In boilers with pulverized firing systems, about 80% of ash released is fly ash, and the rest gets collected as bottom ash. Since Indian coal has a significantly higher amount of ash, it needs an efficient ash handling system.

Thermal-based power plants can produce electricity from coal or other fuel sources. The coal-fired process requires three different steps to turn energy released from burning coal to generating electricity for consumption. Coal fired power plants, while producing power, require a lot of water and produce a lot of pollutants like ash and CO2. Learn how the …
