Gasification of Coal Process. The coal used for gasification is normally about 75 mm pieces which have been subjected to grinding or ball mills. Gasification of the coal basically consists of loading these small uniform pieces by conveyor onto a moving grate located about a quarter of the way up the gasifier.
Feedstocks enter the gasifier at the top, while steam and oxygen enter from below. Any kind of carbon-containing material can be a feedstock, but coal gasification, of course, requires coal. A typical gasification plant could use 16,000 tons (14,515 metric tons) of lignite, a brownish type of coal, daily.

Coal is now being injected into blast furnaces at the rate of 80--200 kg/t of hot metal and this results in a coke saving of 72--180 kg/t of hot metal. The pulverized coal needed for coal injection is produced in coal grinding and drying plants and at present these plants range in capacity from 15 to 240 t/h.
Coal gasification is the process of producing syngas–a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), natural gas (CH 4), and water vapour (H 2 O)–from coal and water, air and/or oxygen.. Historically, coal was gasified to produce coal gas, also known as "town gas".Coal gas is combustible and was used for municipal lighting, and heating ...

The Gasification Unit employs the GEE Gasification Process to convert feedstock coal into syngas. Facilities are included for scrubbing particulates from the syngas, as well as for removing the coarse and fine slag from the quench and scrubbing water. The Gasification Unit includes the following sections: Coal Grinding/Slurry Preparation ...
An integrated gasification combined cycle (IGCC) is a technology that uses a high pressure gasifier to turn coal and other carbon based fuels into pressurized gas—synthesis gas ().It can then remove impurities from the syngas prior to the power generation cycle. Some of these pollutants, such as sulfur, can be turned into re-usable byproducts through the Claus process.
