Types of Coal Peat Peat is not typically considered actual coal but is the very first step in making coal where the decaying plant material is beginning to be compressed and heated. It can still go through the same coal drying process to help it burn, and is used for fuel in some regions of the world. Lignite

The following types of coal have been identified according to their physical properties: (i) Peat Coal: This is the first stage in the change of wood to coal. It is light brown and friable. Producer gas is manufactured from peat. It is also known as brown coal. (ii) Lignite Coal: Lignite burns with much smoke and flame.

There are four different types of coal: Anthracite – contains between 86% and 98% carbon by weight and it burns in boilers slowly Bituminous – contains between 69% & 86% carbon by weight Sub-bituminous – contains less carbon, more water and is a less efficient source of heat for boilers Lignite – contains up to 70% water by weight.

Carbon and energy content determine the four major types of coal and how they are classified. Bituminous coal or subbituminous coal is used by the majority of US power plants to generate electricity. A fifth type of coal is used in the steel industry, known as metallurgical coal. When coal seams are close to the surface, strip mining is used.

What are the 4 different types of coal? Coal is classified into four main types, or ranks: anthracite, bituminous, subbituminous, and lignite. The ranking depends on the types and amounts of carbon the coal contains and on the amount of heat energy the coal can produce. What is coal in BYJU's? Coal is a black hard rock, flammable in nature.

Anthracite is a hard, black, shiny coal form which contains pretty much no moisture. It also has a very low volatile content and because of these factors coupled together, it burns with little or no smoke, meaning it is marketed as a smokeless fuel. Here at Pearson Fuels, we are the leading coal merchants for all your coal related needs.

What are the types of coal? There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalification," during which buried plant matter changes into an ever denser, drier, more carbon-rich, and harder material. The four ranks are: Anthracite: The highest rank of coal. Read More
