A continuous steam generator including a combustion chamber with a plurality of burners for fossil fuel is provided. A vertical gas duct is connected downstream of the combustion chamber on the hot gas side, in an upper region via a horizontal gas duct. The outside wall of the combustion chamber is formed from evaporation pipes which are welded together in a gas-tight manner and mounted upstream of a water separator system on the flow medium side and from superheater pipes which are welded together in a gas-tight manner and mounted downstream of the water separator system. The water separator system includes a plurality of water separation elements, each element includes an inlet tube which is connected to the respective upstream evaporation for tubes, which extend into a water evacuation tube. A distributer element is arranged on the evaporator side between the respective water separator element and the inlet collector.

A method for operating a directly heated, solar-thermal steam generator is provided. As per the method, a nominal value {dot over (M)}s for the supply water mass flow {dot over (M)} is conducted to an apparatus for adjusting the supply water mass flow {dot over (M)} wherein, at the adjustment of the nominal value {dot over (M)}s for the supply water mass flow {dot over (M)}, account is taken of a correction value KT, by which the thermal effects of storage or withdrawal of thermal energy in an evaporator are corrected.

A forced-flow steam generator includes first and second steam generator pipes which form a surrounding wall, wherein the first and second steam generator pipes are welded in a gas-tight fashion and are traversable by flow in a vertical direction. A passage collector is arranged within the surrounding wall, wherein the passage collector connects the first steam generator pipes with the second steam generator pipes. The first steam generator pipes are connected at an outlet side to an inlet side of the second steam generator pipes, wherein the second steam generator pipes are connected in series with the first steam generator pipes. Each of the second generator pipes has a restrictor device. Further, a power plant with a forced-flow steam generator is provided.

A method for producing steam generator tubes is provided. The method is intended to allow a technically particularly simple production process and at the same time allow particularly high flexibility with regards to the materials that may be used to achieve a particularly high efficiency of a steam generator. For this purpose, an insert is fixed in slots of a former shaft, the former shaft with the insert is introduced into a steam generator tube, the fixing of the insert on the former shaft is released and the former shaft is removed again from the steam generator tube.
