Continuous steam generator

A continuous steam generator, comprising:

• a combustion chamber including a plurality of burners for fossil fuel;
• a vertical gas duct, disposed downstream of the combustion chamber and mounted in an upper region on a hot gas side above a horizontal gas duct;
• the horizontal duct;
• a plurality of evaporator tubes;
• a plurality of superheater tubes;
• and
• a moisture separation system,
• wherein a surrounding wall of the combustion chamber is formed, in a lower region, from the plurality of evaporator tubes welded together in a gas-tight manner and mounted upstream of a moisture separation system on a flow medium side and in an upper region, from the plurality of superheater tubes welded together in a gas-tight manner and mounted downstream of the moisture separation system on the flow medium side,
• wherein part of the surrounding wall facing the vertical gas duct is inclined inward below the horizontal gas duct, thereby forming with a first bottom of the adjacent horizontal gas duct a projection extending into the combustion chamber, and
• wherein a boundary between the regions of the evaporator tubes and the plurality of superheater tubes is disposed directly above the projection in an essentially horizontally circumferential manner around the combustion chamber in a region of the bottom of the horizontal gas duct.
