Apparatus for impinging with a second fluid a reaction space through which a fluid flows

摘要

In an apparatus for impinging with a second fluid a reaction space through which flows a first fluid, which apparatus is composed of a tubular element (2), which can be impinged with the second fluid, having at least one nozzle (4) for the outlet of the second fluid from the tubular element (2) into the reaction space and at least two tubes (coolant tubes) (7) which extend in parallel to the tubular element (2) and through which coolant can flow, in which apparatus the tubular element (2) and the coolant tubes (7) have shared wall parts (7A) simpler manufacturability and stability and improved efficiency are achieved by the coolant tubes (7) or the tubular elements (2) being constructed as profiled tubes formed in one piece having outer tubular parallel bridges (8) and the free longitudinal edges (8A) of neighbouring bridges (8) being welded together directly or indirectly with the insertion of tubular parallel metal sheet strips, forming the tubular element (2) or the coolant tubes (7). <IMAGE>
