Abstract
A steam generator is provided. The steam generator has a combustion chamber having a peripheral wall formed at least partially from gas-proof, welded steam generator pipes, at least two additional inner walls formed at least partially from additional steam generator pipes which are arranged inside the combustion chamber. The inner walls are connected one behind the other on the flow medium side by an intermediate collector. The steam generator has a high service life and is reliable. The flow medium on the inlet of the inner wall upstream of the intermediate collector has a lower temperature than that of the flow medium on an inlet of the peripheral wall.

A steam generator, comprising:
- a combustion chamber having a peripheral wall formed at least partly from gas-proof, welded steam generator pipes;
- an inner wall and a further inner wall formed at least partly from additional steam generator pipes,
- wherein the inner wall and the further inner wall are arranged inside the combustion chamber,
- wherein the further inner wall is connected downstream from the inner wall on a flow medium side by an intermediate collector, and
- wherein a flow medium has a lower temperature at an inlet of the inner wall than a flow medium at an inlet of the peripheral wall.
A method for operating a steam generator having a combustion chamber with a peripheral wall formed at least partly from gas-proof, welded steam generator pipes, comprising:
- forming an inner wall and a further inner wall at least partly from additional steam generator pipes;
- arranging the inner wall and the further inner wall inside the combustion chamber;
- connecting the further inner wall downstream from the inner wall on a flow medium side by an intermediate collector, and
- supplying a flow medium having a lower temperature at an inlet of the inner wall than a flow medium supplied at an inlet of the peripheral wall.
