Coal is a typical conventional solid fuel that has been exploited as an important source of fuel by humankind for thousands of years. The main use of coal is as fuel for electric power plants for which more than 50% of the coal produced in the world is used. The simplest use of coal is to burn it for heat.
The former can produce 22000 MT per annum, while the latter produces 6500 MT. Jharkhand has reserves of more than 13.5 billion tonnes of coal and is used in various industries. The types of coal used in the iron and steel industry differ. Coal and steel industry Coal industries in Jharkhand
interest in India is the use of a coal gasification plant in combination with a Direct Reduction plant. The coal gasification plant would use local Indian coals to generate a synthesis gas (or syngas) that can be an acceptable reducing gas source for producing DRI in a shaft furnace. Coal Gasification There are three general types of coal ...
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. The rank of a coal deposit is determined by the amount of pressure and heat that acted on the plants ...

Met coal encompasses a wide range of quality grades including hard coking coal, semi-hard coking-coal, semi-soft coking coal and pulverised coal for injection (PCI). All are used to make steel. Met coal typically …
Coke. Coking coal is converted to coke by driving off impurities to leave almost pure carbon. The coking coal is crushed and washed. It is then ‘purified or ‘carbonised in a series of coke ovens, known as batteries, where the coking coal is heated to 1000-1100ºC in the absence of oxygen for 12-36 hours.
Coking coal must be low in sulfur and requires more thorough cleaning than coal used in power plants, which makes the coal more expensive. In 2022, the average delivered price of coking coal to coke producers was about $196 per short ton—about 4.4 times higher than the average price of coal delivered to the electric power sector.
Coal is a sedimentary deposit composed predominantly of carbon that is readily combustible.

Key terminologies. Coking coal: a type of coal that is used in the production of steel. Anthracite: a hard and compact type of coal that has a high carbon content. Pulverised coal injection (PCI coal): a method of injecting pulverized coal into a blast furnace to improve the efficiency of the iron-making process. Met coke: a type of coke …
Coal is mainly used as a fuel for production of electric power plants for which over 50% of the coal produced in the world is used. Another significant application of coal is cement production, steel manufacturing, and as liquid coal. Coal is also used to burn for heat as a cooking and heating fuel in Western nations.
Currently, there are two primary means of DRI production in India: small-scale rotary kilns using local coal and iron ore lump, and large-scale shaft furnace plants using natural gas …
India will probably account for ∼ 25% of the increased energy demand from 2017 and 2040. Coal-based energy would meet ∼ 42% of the incremental demands (Ray 2021). These trends indicate that fossil fuel will be continued to be used as a power source well into the 2040s, with projected emissions reaching their peak in 2043 (Frank 2015).

Coal is primarily used as fuel to generate electric power in the United States. In coal-fired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into high-pressure steam, which drives a turbine, which produces electricity. In 2019, about 23 percent of all electricity in …
