摘要： A regenerative air preheater with guide devices serving the supply and exhaust of flue gas as well as air to be heated from at least two separated partial streams and with a heat exchanger body, which heat exchanger body, by means of a relative movement between the guide devices and the heat exchanger body, alternately has passed through it heat emitting flue gas and air to be heated, whereby the temperature of the separated partial streams is regulatable. On the side of the flue gas outlet from the heat exchanger body between the dome-like guide devices for the air to be heated, a cover cap is arranged in the vicinity of one exhaust gas partial stream, which cover cap is provided with individual exhaust channels for transporting of the one exhaust gas partial stream into the other exhaust gas partial stream.

摘要： The method for manufacturing heat exchanger elements includes the steps of forming an open tubular base body having a longitudinal extension having a width that is substantially greater than the height thereby defining narrow and wide sides of the tubular base body. In the longitudinal extension of the tubular base body a longitudinal opening with longitudinal edges remains. Two strips of sheet metal are removed from a supply roll and corrugated to form corrugated sheet metal strips. The open tubular base body and the corrugated sheet metal strips are advance continuously and parallel to one another in the direction of the longitudinal extension through a fastening device such that the wide sides face the corrugated sheet metal strips. The corrugated sheet metal strips are pressed onto the wide sides and then fastened to the wide sides at some locations of contact between the wide sides and the of corrugated sheet metal strips. Subsequently, the longitudinal edges of the opening are joined to close the opening and form a closed tubular structure. During fastening of the corrugated sheet metal strips onto the wide sides, the wide sides of the open tubular base body are supported from the interior by a support structure.

摘要： A method of securing tubes between tube sheets of a heat exchanger, with the tube sheets being interconnected via a housing. The tubes and/or the tube sheets of are made of a steel that has to be annealed after a welding process. To be able to provide a stress-free connection between the tubes and the tube sheets, and to enable simple repair of the tubes, the length of at least one end of each tube is extended by welding thereto a tubular piece that is made of a material that can be welded without subsequent thermal treatment being required. Sleeves that extend the length of the holes in the tube sheet are welded onto the outer surface of at least one of the tube sheets. At least the free end of each sleeve is made of a material that can be welded without subsequent thermal treatment being required. One end of each tube, if such end is not provided with a tubular extension, is welded onto a tube sheet. A final thermal treatment is carried out after all welding steps that require a subsequent thermal treatment are concluded. The tubes are indirectly connected to those tube sheets that are provided with sleeves by welding the free ends of the tubular extensions of the tubes to the sleeves.

摘要： The present invention relates to a method and devices for mixing at least two individual streams having different variables. In order to produce a low-loss, effective mixing within a short flow section, at least one eddy impulse is produced in the cross section of flow of at least one individual stream, which impulse spreads out downstream transverse to the direction of flow to form a discrete eddy system whose components transverse to the main direction of flow overlap into the other flow cross section of the other individual stream. This eddy impulse can be produced either by at least one curved surface or by at least one edge of a surface or of a body. The eddy impulse is preferably produced by two burble (flow break-away) edges of a delta-shaped insert element which extend at an acute angle to each other.

摘要： An adjustably operable heat transfer system for cooling tower installations, the heat transfer units consisting of a section of only "wet" operating evaporative heat exchanger units and a section of dual-purpose heat exchanger units which are adapted for alternative or simultaneous wet evaporative heat transfer and "dry" convective heat transfer.
