The type of coal that burns with great heat and very little smoke is?

The type of coal that burns with great heat and very little smoke is anthracite. Anthracite is a hard, shiny, black coal that is found mainly in the eastern regions of the United States. It is the highest grade of coal and contains a high percentage of carbon, which makes it burn very cleanly with very little smoke. Due to its high carbon content, anthracite burns with intense heat and produces very little ash. It is often used in residential and commercial heating systems, such as furnaces and boilers. It is also used in the production of steel and other industrial applications. In contrast, lignite is a softer and less dense type of coal that burns less efficiently than anthracite. Steam coal is a bituminous coal that is often used to generate electricity in power plants. Peat is a precursor to coal that is formed from the decay of organic matter and is used mainly for fuel and gardening purposes.
