Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Coalfired industrial boilers play a key role for process and comfort heat in the industrial, residential and commercial sectors. Currently no international world's best practice (WBP) for efficient coalfuelled industrial and commercial boilers exists. This is due to several factors including the type of coal, efficiency and size of the boiler.
