Difference Between Black and Brown coal

The term 'black coal' is used in Australia to refer to anthracite, as well as bituminous and sub-bituminous coals. Brown coal is also called lignite; it contains less carbon and so has less chemical potential energy than black coal and has more moisture in it.

Is brown coal better than black coal?

Brown coal is not as efficient at burning as black coal (because of its high moisture and low carbon content) and therefore it produces up to 30 percent more greenhouse gas emissions than black coal when used to generate electricity.

Why does Victoria use brown coal?

Coal-fired generators

Unlike many other states, the major coalfields of Victoria contain brown coal. The high water content of this coal makes it less suited for combustion without specialised technology.

What is the difference between peat brown coal and black coal?

Brown coal (lignite) is classed as a low-rank coal because it has a high ash and moisture content, and less carbon, which means that it produces less energy when it is heated. ... Black coals are ranked higher because they are harder, have more carbon, less ash and less moisture and thus a higher energy content.

Is brown coal bad?

Lignite, often referred to as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed peat. ... It is mined all around the world and is used almost exclusively as a fuel for steam-electric power generation. Lignite is the most harmful coal to human health.

Which country has the cleanest coal?

Anthracite is found on the east coast in the US, South Africa, Australia, Western Canada, China and Russia. Two-thirds of Russia's coal reserves are anthracite. Because of its efficiency and thus less carbon and sulphur usage per watt of power, anthracite is also the 'cleanest' coal in the world.

Who has the best coal in the world?

What is brown coal used for?

Does Australia export brown coal?

In Australia, brown coal is currently considered unsuitable for export and is used primarily to generate electricity in domestic power stations. ... Victoria is the only State in which brown coal is mined.

How much coal does Australia have left?

Coal Reserves in Australia

Australia has proven reserves equivalent to 1,231.3 times its annual consumption. This means it has about 1,231 years of Coal left (at current consumption levels and excluding unproven reserves).

What is the highest grade of coal?

Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high percentage of fixed carbon and a low percentage of volatile matter.

Which coal has lowest carbon content?

Lignite contains 25%–35% carbon and has the lowest energy content of all coal ranks.
