摘要： A liquid-cooled cooling screen for an entrained-flow gasifier for gasification of fuels in dust or liquid form using a gasifier agent containing free oxygen, at pressures between atmospheric pressure and 8 MPa and gasification temperatures between 1200 and 1900° C. The liquid-cooled cooling screen of which the cooling pipes in the central cylindrical section have thinner walls than the cooling pipes in the lower and upper conical sections. A cooling screen design has sufficient strength under high pressure difference over the cooling screen wall, a pipe wall thickness which ensures reliable operation of the cooling screen and high heat throughput, and pressure equalization between the cooling screen gap and the reaction chamber under all operating circumstances.

摘要： Devices for a three-stage scrubbing system for treatment of hot crude gases and liquid slag by an entrained flow gasification. Crude gas and slag are conducted downward into a water bath in a central tube. The upper part of the central tube consists of a double-threaded tube screen welded in a gas-tight manner, in which water is injected directly as the first scrubbing and cooling stage in the interior thereof. In the water bath, a bubble column is formed, which simultaneously constitutes the second scrubbing and cooling stage. Surface bodies arranged in three layers increase the scrubbing effect. After leaving the bubble column, the crude gas is again sprayed with water in a cavity, wherein one or more nozzle rings are disposed. This forms the third scrubbing stage. The crude gas then leaves the quenching and scrubbing apparatus in steam-saturated form at 200-220° C. and is sent to further treatment.
