Abstract (en)
[origin: EP0922913A2] The water in a preset part of the double-walled combustion chamber flows more rapidly through a constricted part (64) in a flow duct (46d). The narrow point in the flow duct is formed by a peripheral circle-arc shaped weld seam (48a) and a single weld seam (48f). The two side walls (14,16) and the back wall (12) of the combustion chamber form a U-shaped unit.
