ABSTRACT:
An improved waste-heat boiler for cooling and recovering heat from the hot gaseous product of a partial combustion process is disclosed. The waste-heat boiler contains gas tubes, the straight parts of which protrude through the separation plate between the cooling chamber and the gas inlet chamber into the gas inlet chamber. The straight parts of the gas tubes are surrounded by cooling jackets, which are connected with the inlet ends of the gas tubes. In the ring-shaped spaces between the straight parts of the gas tubes and the cooling jackets axial tubular conducting bodies are present. The axial tubular conducting bodies are connected with coolant supply lines wherein water is pumped for cooling the gas inlet ends.
