These coals are also called as metallurgical coals Coking coals form a part of the bituminous group Peat Lignite Sub bituminous Semi anthracite and Anthracite are all non coking coals So also are some of the bituminous coals Non coking coals are mainly used for power generation
·A Chinese sub bituminous Shenfu SF coal was steam treated under atmospheric pressure and the caking and coking properties of the treated coals were evaluated by caking indexes G RI and crucible coking results show that steam treatment can obviously increase the G RI of SF coal When the steam treated coals were
·Coking coal is coking coal or also known as metallurgical coal This type is an exclusive commodity in the development of the coal industry It is called exclusive because this coal has a higher quality than the coal usually produced by coal companies in Indonesia so far This coal is produced by roasting in a coking oven in a reduced state
Official Energy Statistics from the Government steam coal Steam coal Coal burned primarily in boilers to generate steam for the production of electricity or for process heating purposes or used as a direct source of process coal also known as thermal coal refers to all coal not classified as coking or metallurgical coal See coal grade

Application Coking coal is mainly used to produce high quality coke which is essential for iron and steel making Thermal coal also known as steam coal is used for generating power by heating it to produce steam to run turbines for electricity generation Physical Properties Coking coal has a higher carbon content and a greater ability to
Metallurgical coal also known as coking coal or coke is used mainly in steel production The process of making steel involves heating metallurgical coal to very high temperatures until it chemically changes into coke and then injecting the coke into a blast furnace filled with iron ore and limestone Thermal coal also known as steam coal
They usually account for about 15% ranging from 0% to 20% depending on the mill of the total coal and come mainly from the USA but Canadian and Australian LV coals are also commonly used 3 Medium volatile hard coking coals tend to be split into at least three subgroups
