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.

• peat – has low carbon and high moisture content.
• anthracite – highest rank of coal and had low sulfur and high carbon content.

• bituminous – it is soft and dense and sometimes has band of dull or bright material in it.

What are the 4 types of coal and what is the difference between the types?

The four types of coal are peat, lignite, bituminous, and anthracite. … Lignite has a higher heat content than peat but is still not the most desired form of coal. However, lignite makes up almost half of our known coal reserves. Bituminous coal is formed as more pressure is applied to lignite coal.
