Abstract
A method and device for cooling hot crude gas and slag from entrained flow gasification of liquid and solid combustibles at crude gas temperatures ranging from 1,200 to 1,800° C. and at pressures of up to 80 bar in a cooling chamber disposed downstream of the gasification reactor by injecting water. The cooling water is distributed, with a first portion being finely dispersed into to cooling chamber and a second portion being fed at the bottom into an annular gap provided between the pressure-carrying tank wall and an incorporated metal apron for protecting said pressure-carrying tank wall. The second portion of the cooling water flows upward in the annular gap and trickles down the inner side of the metal apron in the form of a water film.
