Abstract (en)
[origin: ES8307885A1] This invention relates to the gasification of coal. An oxygen jet having a pointed flame is engendered in situ, so as to strike the coal with a sheath of steam. The resultant fuel gas is drawn off while flowing in counterflow with the jet of oxygen and is brought to the surface through the same bore which had served the purpose of supplying oxygen. The invention is particularly applicable to the underground gasification of coal in situ.
