Abstract

DC60 (31/07/57) Gasification reactor for entrained-flow gasification of powdered solid carbon fuels, having a first reaction chamber provided at the top of the reactor, the top of which is used for a feedstock, the side walls of which are provided with internally cooled membrane walls or coils which permit the liquid slag to flow freely without solidifying the slag surface, and the bottom of which is provided with openings for a slag outlet and a syngas outlet, having a second chamber connected to the bottom of the openings in which the raw gas is kept dry and cooled by radiant cooling and a device provided for creating a water curtain, the bottom of the second chamber connected to a third chamber which is used for a feedstock, a containment device for a water bath connected to the third chamber, a device also provided with a discharge device for the water/slag mixture, and a discharge device for Raw gas from the reactor arranged at the bottom or side of a third chamber, having symmetrical projections along the axis, which cause the transition from the first to the second chamber, and the lower edge of which is arranged at the same level or above the level of the free-falling water curtain outlet.
