Underground coal gasification UCG is a method of converting unworked coal - coal still in the ground - into a combustible gas UCG technology allows countries that are endowed with coal to fully utilise their resource from otherwise unrecoverable coal deposits UCG uses a similar process to surface gasification...
Gasification is different than combustion of coal to make heat for electric power Instead of burning the coal, the feed coal is combined with water in a slurry The slurry is heated into steam, and oxygen is added in a thermal-chemical process which breaks down the matrix molecules in the coal...
Underground coal gasification UCG is one of the clean coal technologies being investigated by Eskom Conceived in the late 1800s, it is a process where coal is gasified in situ, and has been developed in various countries across the world A matrix of wells is drilled into the coal...
Underground Coal Gasification UCG is one of several clean coal technologies being investigated by Eskom UCG, a process where coal is gasified in place, was conceived in the late 1800s and has been developed in various countries across the world A matrix of boreholes is drilled into the coal seam....
It further introduced a definition for gasification that reads a process applied to non-mined coal seams, using injection and production wells drilled from the surface, which enables the coal to ,...
