摘要
A method of generating gas and coke dust by means of rapid degasification and rapid vaporization, with simultaneous extensive desulfurization, of coal ground into dust. In a first step, one portion of coal is subjected to complete or partial vaporization. In a second step, which immediately follows the first step, another portion of coal is subjected to degasification in the same or in associated reaction chambers. In the degasification, the solid and gaseous products obtained during the vaporization which are at a higher temperature level than that of the degasification step, transfer heat directly to the coal introduced into the degasification step, thus for covering the heat required for the degasification.
