Coal is primarily made of Carbon, Hydrogen, Oxygen, Nitrogen, Sulphur and varying quantities of aluminium, zirconium and many other minerals. In terms of increasing carbon content, hardness, heat content and decreasing moisture coal is of three types viz. Lignite, Bituminous and Anthracite.

Called Brown Coal, vast reserves of lignite are available in limited areas of the world. Australia, US and China have the major reserve of Lignite. Germany leads the pack with the largest number of power plants burning Lignite. In US, most of the reserves are located in the North Dakota province.
Brown coal is pulverised and then burned in largescale boilers. The heat is used to boil water and the steam is used to drive turbines that generate electricity. Brown coal forms the basis for 92 percent of electricity generation in Victoria.
SubBituminous Coal Subbituminous coal is about 100 million years old. It contains more carbon than lignite, about 3545%. In many parts of the world, subbituminous coal is considered "brown coal," along with lignite. Like lignite, subbituminous coal is mainly used as fuel for generating electricity.
Jul 30, 2009· Lignite is the second of six stages of coal maturity. Black coal is generally at least subbituminous in grade (the next higher grade than lignite). However sometimes even bituminous coal is brown.
The Coal Facts: thermal coal vs. metallurgical coal By Paula Baker FILE In this Dec. 3, 2009 file photo, workers load coal into a truck outside a coal mine in Dadong, Shanxi province, China.
Dec 06, 2008· Best Answer: The main similarity is that all three fuels are derived mostly from plants. Peat grows in swamps or bogs. When the plant dies, it falls into the water. The water slows down the rate of biological decay, a lot.
The bulk density of coal depends on the specific type of coal. It can range from 40 to 58 pounds per cubic feet, or 641 to 929 kilograms per cubic meter. The three types of coal are anthracite coal, bituminous coal and lignite coal.
What is the difference between cocopeat and mined peat? ... What is the difference between this two in terms of physical, chemical and biological characteristics? ... Brown coal, lignite 60 75 4 ...
subbituminous coal. generally dark brown to black coal, intermediate in rank between lignite and bituminous coal according to the coal classification used in the United States and Canada. In many countries subbituminous coal is considered to be a brown coal.
In Great Britain and other countries, the term brown coal is used to describe those lowrank coals (lignite and subbituminous coal) that generally have a brown colour. In Germany lignite, subbituminous coal, and some highvolatile bituminous coal s are classified as brown coals ( .
The difference is that subbituminous is the transition stage from lignite to bituminous coal. Bituminous coal is widely used in the United States and across Europe.
Lignite or brown coal is even poorer than bituminous coal but it is still extensively mined. Width of the sample from Germany is 6 cm. Peat is the source material of all the other coal types shown above. It accumulates in wetlands and is composed of plant remains.
The bulk density of coal depends on the specific type of coal. It can range from 40 to 58 pounds per cubic feet, or 641 to 929 kilograms per cubic meter. The three types of coal are anthracite coal, bituminous coal and lignite coal. Anthracite coal has a bulk density of 50 to 58 pounds per cubic feet, or 800 to 929 kilograms per cubic meter.
As nouns the difference between charcoal and lignite is that charcoal is (uncountable) impure carbon obtained by destructive distillation of wood or other organic matter, that is to say, heating it in the absence of oxygen while lignite is a lowgrade, brownishblack coal.
