Abstract

Waste heat steam generator for hot, dust-loaded gases under overpressure, with a gas feedline, with a gas exhaust line as well as with heat exchanger elements through which a coolant flows. The gas feedline is conducted inside a gas exhaust line, which opens from above into heat exchanger space which is concentrically arranged in a pressure vessel. The heat exchanger space is open at the lower end and in it the heat exchanger elements are supported. The space between the containment walls of the heat exchanger space and the pressure vessel wall at the upper end of the pressure vessel is connected to the gas exhaust line. The pressure vessel bottom in the form of a funnel is connected to an ash removal device. The containment walls of the heat exchanger space are provided with heat exchanger tubes.
