Abstract: The waste heat recuperator can be used in horizontal flue ducts for flue velocities exceeding 25 m/s. The tube headers are made of plane tube plates with welded-on semi circular feed heads. The recuperators are mounted in the flue duct without rigid connections in a free standing manner on the flue duct base. The sealing between the heat exchanger sections on the heat duct base is effected by the weight of the element only with inserted soft sealing material. The tubes of the heat exchanger are expanded in or welded onto square plane tube plates. Sealing of the exchanger elements on the top part of the flue duct is carried out by solid buckling with parallel structure enabling to remove quickly any damaged element and replace it by a new one from stock.
