Abstract (en)
[origin: WO2016109903A1] The invention relates to a heat exchanger (100) for an interior space of a combustion plant, comprising a plurality of heat exchanger pipes (11) extending in parallel over a defined length range (H), which heat exchanger pipes are altogether surrounded by a refractory protective lining (20) over said length range. Between the heat exchanger pipes (11) and the protective lining (20), at least one intermediate space (30) is formed. The heat exchanger further comprises gas supply means for supplying a protective gas to the at least one intermediate space (30). Together with webs (12) that mechanically connecting the heat exchanging pipes, the heat exchanger pipes (11) form a pipe wall (10). The at least one intermediate space (30) between the heat exchanger pipes (11) and the protective lining (20) is formed on both sides of the pipe wall (10). The gas supply means comprise a gas distribution box (40) having at least one gas inlet opening (41) for the protective gas and a plurality of gas outlet openings (42), which terminate in the at least one intermediate space (30) between the heat exchanger pipes (11) and the protective lining (20).
