Abstract
A continuous-flow steam generator includes a combustion chamber with evaporator tubes for fossil fuel. The combustion chamber is followed on the fuel-gas side by a vertical gas flue through a horizontal gas flue. When the continuous-flow steam generator is in operation, temperature differences in a connecting portion, which includes an outlet region of the combustion chamber and an inlet region of the horizontal gas flue, are to be kept particularly low. For such a purpose, of a plurality of evaporator tubes capable of being acted upon in parallel by flow medium, a number of evaporator tubes are guided in the form of a loop in the connecting portion.
