brown coal processing

brown coal processing,Lignite - WikipediaLignite, often referred to as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed peat. It is considered the lowest rank of coal due to its relatively low heat content. It has a carbon content around 60–70 percent. It is mined all around the world and is used almost exclusively as a fuel for.brown coal processing,The conversion of brown coal to a dense, dry, hard material .Advantages of this densified brown coal process are that a hard, dense, fuel product can be manufactured from a raw brown coal of high initial water content without the need for, or prolonged, expensive drying conditions at elevated temperature. The resultant product is suitable either as a briquette equivalent fuel, or as.
