摘要： A deaerating and degassing system for a power plant condenser, comprising a condensate collector and optionally an air cooler, whereby the deaerating and degassing system includes a suction aggregate and a suction line for a steam-inert gas mixture and the suction line connects the condenser or, in case an air cooler is present, the air cooler of the condenser, to the suction aggregate. In the suction line, there is a direct-contact condensation device, for example, a packing column or a tray contact apparatus, through which the steam-inert gas mixture can flow in direct contact in a countercurrent to the chilled condensate from the condensate collector.

摘要： A power plant, from which large amounts of process steam are removed and to which large amounts of make-up water are supplied continuously, has a degassing system (5) for the make-up water supplied, which as part of the condensation system is connected to the condenser (10) of the power plant. Bleed pumps (25) are connected to the condenser (10) via a first suction line (15) and to the degassing system (5) via a second suction line (16) and remove a mixture of steam and non-condensable gases from the power plant. A control member (22, 23), such as for example a regulating valve, a regulating diaphragm or a readjustable restrictor, is arranged in at least one of the two lines (15, 16), with the result that the suction capacity in that line and the distribution of the suction capacity to the two lines (15, 16) can be adjusted during operation of the power plant.

摘要： A low-pressure turbine is provided with stationary and rotating blades, and the blades have a coating that is hydrophobic or water-repellant and has a smooth surface. The coating preferably contains amorphous carbon. The hydrophobic property of the coating has the result that small droplets contained in the steam phase, upon impacting a coated blade, roll off across the blade in the form of small droplets and further follow the steam path. This prevents moisture losses and increases the efficiency of the turbine. It also prevents the small droplets on the blades from coalescing into larger droplets or into a fluid film. This prevents droplet impingement erosion caused by the impact of large droplets on the blading and other components of the turbine.
摘要翻译：低压涡轮机设置有固定和旋转的叶片，并且叶片具有疏水性或防水性且具有光滑表面的涂层。涂层优选含有无定形碳。涂层的疏水特性使得蒸汽相中包含的小液滴在撞击涂覆的刀片时以小液滴的形式滚过叶片，并进一步跟随蒸汽路径。这防止了水分损失并提高了涡轮机的效率。它还可防止叶片上的小液滴聚结成较大的液滴或流体膜。这防止了由大液滴对叶片和涡轮机的其它部件的冲击引起的液滴冲击侵蚀。

摘要： In a hydraulic method, tubes (3) of an heat exchanger are rolled in in tube plates (1), and rounded tube inlet pieces are formed from the same tube (3) by means of the same device in the same work operation. For this purpose, the tubes (3) are inserted into the bores (2) of a tube plate (1) and cut off with an excess length. The tube (3) is widened by means of a widening machine over the entire depth of the bore (2), so that the tube (3) adheres to the inner wall of the bore (2). At the same time, the projecting tube end (10) is pressed on the mandrel (4) of the widening machine in the direction of the tube plate (1) by means of a further hydraulic shaping device (11) with a swept-back shape (12) until the tube end (10) achieves a trumpet shape. The advantage of the method resides in shortening the operating time with a device which executes both widening and formation of the tube inlet piece hydraulically. Given that the tube inlet piece is produced from the same tube (3), no seam is produced between the tube (3) and tube inlet piece, thus avoiding a site of faltering flow.
