  • Method of and apparatus for in situ gasification of coal and the capture of resultant generated heat
    Patent number: 4010801
    Abstract: A method of in situ gasification of coal includes the steps of releasing reactant materials in a coal bed in a manner such that the reactants are directly exposed to the burning face of a coal bed under preselected temperatures and pressures whereby the incomplete combustion of the coal is affectively controlled. In one preferred form of the method, the heat generated from the combusted materials is captured and separated from the recovered gas so that the heat can be converted to other forms of energy separately from the recovered gas.
