Abstract
A steam generator has a combustion chamber which is configured for an approximately horizontal main direction of flow of the fuel gas and which is followed on the fuel-gas side, via a horizontal gas flue, by a vertical gas flue. The containment walls of the combustion chamber are formed from evaporator tubes. Temperature differences between adjacent evaporator tubes of the combustion chamber are to be kept particularly low in all the load states of the steam generator. For this purpose, a first group and a second group of evaporator tubes can be acted upon in each case in parallel by a flow medium. The first group of evaporator tubes is connected in series with the second group.
