There are different streams for transporting of coal. The streams are operated as per requirement. Some of the CHP's are now days are operating beyond their design lives. Working conditions in CHP are dusty, dirty and often ...
Crushing the coal into fine powder makes it easier to burn it more completely (in fact, powdered coal is explosive when airborne!) This is important, because the act of burning coal requires the use of energy, so by making the coal easier to burn, less heat energy is being used to access the energy locked within the coal. It is also important to ensure the coal can be burned more .
Lignite: Lignite coal, aka brown coal, is the lowest grade coal with the least concentration of carbon. Lignite has a low heating value and a high moisture content and is mainly used in electricity generation. The precursor to coal is peat. Peat is a soft, organic material consisting of partly decayed plant and mineral matter. When peat is placed under high pressure and heat, it .

· GRADING OF INDIAN COAL For grading of NonCoking coal useful heat value is used, which is calculated by HU= 8900 138(ash + moisture) kcal/kg 1. if M<2% and VM< 19% then deduct 150 kcal/kg for each 1% reduction in VM 2. M at 40 c and 60% RH Grading does not include coal from North East India Grading of coking coal is done as per their ash content 25. .
The coal formation process involves the burial of peat, which is made of partly decayed plant materials, deep underground. The heat and pressure of burial alters the texture and increases the carbon content of the peat, which transforms it into coal, a type of sedimentary rock. This process takes millions of years. Types, or "ranks," of coal are determined by carbon content.
