Refined coal Wikipedia
Refined coal is the product of the application of a coalupgrading technology that removes moisture and certain pollutants from lowerrank coals such as subbituminous and lignite (brown) coals and raising their calorific values. Coal refining or upgrading technologies are typically precombustion treatments and/or processes that alter the characteristics of a coal before it is burned.Get Price
Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed if dead plant matter decays into peat and over millions of years the heat and pressure of deep burial converts the peat into coal.Get Price
