Combustion chamber shaft with heat exchanger formed by serpentine pipe with bends and discs

摘要

The pipe bends (5) of the heat exchanger (2) run inside the combustion chamber lining (1). The pipe bends are equipped with star-form or meander-form filling pieces (6). The combustion chamber lining in the direction towards a burner supplying the heat exchanger has an area (7) with a reduced cross-section. It is in this that a cooling hose (10) fitted on the outer side is located.
