Abstract
A pressure container forms a shaft gasifier for receiving coarse coal in the form of a coal bed. A burner extends through the pressure container into a chamber therein and produces at least one primary gas jet directed against the coal bed, thereby gasifying the coal and generating a product gas and forming liquid slag. The liquid slag collects in a slag bath tank having an overflow weir over which the collected slag flows and falls freely toward a cooling water bath beneath the chamber. A water jet nozzle directs at least one water jet against the liquid slag as it falls freely between the weir and the cooling water bath. This atomizes the liquid slag, thereby cooling the slag and generating steam. At least a part of the steam is supplied as process steam to the coarse coal.
