  • Underground Coal Gasification netl.doe.gov

    Underground Coal Gasification (UCG) takes advantage of the same chemical reactions of coal to produce product gases, as those occurring in conventional gasifier reactors. The main difference is that in UCG the underground coal seam itself becomes the reactor, so that the gasification of the coal takes place underground instead of in a manufactured gasification vessel at the surface.1 Obviously

    01/09/2017· Underground coal thermal treatment (UCTT) is a recently proposed concept that offers the prospect of converting deeply buried coals into high-value hydrocarbon fuels that have less CO 2 emissions per energy content. In this process, the coal seam is heated by external energy and decomposition products are recovered in the form of gaseous and liquid fuels.

  • Coal-seam fire Wikipedia

    A coal-seam fire is a burning of an outcrop or underground coal seam.Most coal-seam fires exhibit smoldering combustion, particularly underground coal-seam fires, because of limited atmospheric oxygen availability. Coal-seam fire instances on Earth date back several million years. Due to thermal insulation and the avoidance of rain/snow extinguishment by the crust, underground coal-seam fires
