Abstract: A method for producing a housing for electronics in which the housing is formed by a first housing element and a second housing element and in which the housing elements are composed of aluminum or an aluminum alloy. The method further includes connecting the housing elements to one another by welding so that the housing elements are held tightly together. The method also includes producing at least one of the housing elements by a die casting method in which gas that is created in the die-casting method is evacuated from the housing element by helium gas.

Abstract: A method for operating a steam power plant having a water-steam circuit, according to which method the process wastewater produced is collected from the water-steam circuit, in a separated manner according to the degree of contamination thereof, in a number of partial wastewater quantities is provided. At least a first partial wastewater quantity having a first degree of contamination and at least a second partial wastewater quantity having a second degree of contamination are formed in the process. The second degree of contamination is higher than the first degree of contamination. The first partial wastewater quantity and the second partial wastewater quantity are mixed together in such a manner that a combined process wastewater is produced, which is fed to a wastewater treatment plant.

Abstract: The invention relates to a method (5) for producing a housing (1) for electronics that are used to control an electric motor, wherein the housing (1) is formed by a first housing element (30) and a second housing element (40). According to the invention, the housing elements (30, 40) are composed of aluminum or an aluminum alloy. Furthermore, at least one of the housing elements (30, 40) is created by means of a die-casting method (52). The housing elements (30, 40) are connected to each other tightly, in particular in a fluid-impermeable manner, by means of welding (60).

Abstract: A fossil-fueled steam power plant and method, the plant has a water-steam circuit, cooling water circuit, flue gas cleaning system and cooling tower. A fossil-fueled steam generator, steam turbine and condenser are connected to the water-steam circuit. In the cooling water circuit, a cooling tower and condenser are connected such that expanded steam is condensed by the exchange of heat with the cooling water circuit. The flue gas from the generator is cleaned in the flue gas cleaning system, and the cleaning system is supplied with process water. Process wastewater leaves the cleaning system. The cleaning system is connected to the cooling water circuit such that process water required for cleaning system is drawn from the cooling water circuit. To remove contaminated process wastewater, the cleaning system is connected to a wastewater treatment system having an evaporator, where system purified process wastewater is generated.
