Abstract: An air-supplied dry cooler for the condensation of water vapor includes at least one direct-flow condenser and at least one counter-flow condenser (dephlegmator), wherein heat exchanger pipes of the counter-flow condenser are connected to an upper suction chamber, and wherein a cover reducing the discharge cross-section of at least one heat exchanger pipe is provided with cover orifices. The sum of the cross-sectional surfaces of the cover orifices corresponds to no more than the cross-sectional surface of a suction pipe connection to the suction chamber.
Abstract: An electrical circuit breaker, in particular a high-voltage circuit breaker filled with insulating gas, is described. The circuit breaker is furnished with a first contact, in particular, a contact pin and a second contact, in particular, a tulip contact that are movable in opposite directions. The circuit breaker is furnished with a drive mechanism that is coupled to the second contact. The circuit breaker is furnished with a reversing gear that produces a coupling between the second and the first contact. A first indicator element is provided that is associated with the reversing gear.
Abstract: In order to protect heat exchanger pipes (1) in steam boiler systems, special casing elements (2) made of fiber-reinforced ceramic are proposed. The casing elements prevent or reduce the formation of films and corrosion on the heat exchanger pipes and thus enable higher steam parameters of the boiler system and a correspondingly increased thermal efficiency.

Abstract: The present invention relates to a load control device for an engine and to a method for controlling the load. The load control device comprises a compressor for compressing air in an intake system of the engine; an exhaust gas line for discharging an exhaust gas mass flow from the engine; a turbine that is driven by an exhaust gas mass flow supplied by the exhaust gas line and that drives the compressor; a bypass line that branches off the exhaust gas line upstream of the turbine, wherein a first valve is disposed in the bypass line for controlling the mass flow in the bypass line; and an active cooling device that is disposed upstream of the valve.
Abstract: An air condenser with upward oriented tube bundles for condensing steam, wherein the tube bundles form sidewalls of a cell in form of a circumferentially closed, vertically extending polygon, wherein a fan is arranged above the polygon. Two of the circumferential sidewalls of the cell are formed by tube bundles, wherein these sidewalls enclose an angle smaller than 90° and wherein the at least one further side wall is impermeable to air.
Abstract: Method for setting up a condensation plant, for which two tube bundles (2, 3) are placed on a roof-shaped preassembly frame (1) and connected to one another in a first area. The tube bundles (2, 3,), along with the base plates (5, 6) thereof which hold the heat-exchanger tubes, are placed in supports (10) at a roof ridge strut (11) of the preassembly frame (1) in such a way that the mutually facing longitudinal sides (12, 13) of the base plates (5, 6) can be welded together by means of a root seam, before the preassembled roof-shaped tube bundle delta (14) is lifted from the preassembly frame (1) and brought into the installed position.
Abstract: Method for producing a heat exchanger with the following steps: a) hot dip refining a steel sheet to form a corrosion-protection layer (3), wherein the corrosion-protection layer (3) contains zinc and between 0.5% and 60% aluminum; b) removal of the corrosion-protection layer (3) from one side of the steel sheet; c) production of a heat exchanger tube (2) from this steel sheet, wherein the corrosion-protection layer (3) is arranged on the outside; d) provision of ribs (6) of aluminum or an aluminum alloy; e) provision of a flux; f) provision of a filler material (8) containing aluminum and silicon in the connecting region between the ribs (6) and the outside of the heat exchanger tube (2); g) connection of the heat exchanger tube (2) to the ribs (6) in a brazing operation.
