Types and Classifications of Industrial Boilers

There are various types of coal, from anthracite with its high carbon content to bituminous coal, subbituminous coal and lignite (brown coal), which is an even younger coal. Power generating equipment needs to be optimized for these different types of coal. Mitsubishi Power is able to supply the optimum power generating equipment to match any variety, from anthracite to lignite.

Coal-Fired Boiler - an overview | ScienceDirect Topics

Coal-fired boilers are mainly operated at either subcritical or supercritical conditions. From a thermo-physics perspective, two phase mixtures of water and steam are replaced by a single supercritical fluid when the boiler pressure increases above the critical pressure of 22.12 MPa and the corresponding saturation temperature of 374 °C (Shen and Cheng, 2004).

How to Run a Coal Fired Boiler at the Best Efficiency

Aug 28, 2018 · 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.
