coal based thermal power plants coal mills for thermal A higher Hardgrove index indicates the coal is easier to grind. 50 HGI normally is taken for calculating the base capacity of the mill. When coal with HGI higher than 50 is fed to the pulverizer the output will be higher than base capacity and below 50 HGI the output will be lower.

Working Principle Of Wind Energy

Working Principle of Wind Energy. Wind is simply defined as moving air. When the earth heats up from sunrays it releases wind, this is a balanced reaction meant to cool the earth. The sun heat is felt more on dry land than on the sea. The air expands and easily reaches maximum high altitudes, then cool air drops down and moves as wind.
