摘要

A continuous flow steam generator with a double-flue construction has a vertical gas flue with an ascending conduction of fuel gas. The combustion chamber rear wall is inclined inwards and towards the combustion chamber in an upper part region and thereby forms, with the bottom of an adjoining horizontal gas flue, a nose which projects into the combustion chamber. Some steam generator tubes of the lower part region of the combustion chamber rear wall are led upwards, uninclined, as supports for the combustion chamber rear wall, as far as a supporting structure located outside the conduction of the fuel gas.
