凝汽管

The operation principle of the air cooling system is to lead the gas from the steam turbine to cooling fin which is 40 meters high, then, cool the gas using air outside the pipe and wind from the cooling fan. Change the gas to water, and now collect the water to condensational water tank.

直接空冷系统的工作原理是将凉水塔取代，将汽轮机排汽管引至四十米以上的高度，进入带翅片的管束，通过管内始终循环，再利用循环中的空气和风机向上的引风来冷却，将蒸汽凝结成水，冷凝水从管束流至收集系统至冷凝水箱，将水反复使用。

Place non-condensing steam outlet pipe on dephlegmator bundles, do the adjustment and aiming.

2.7.6 吊装不凝汽出口汇集管到逆流管束上，进行调整和对准。

Which might fall through the tube opening into the dephlegmator header if not covered. The temporary installed steel sheet is to be removed after the steam distribution duct has been installed.

建议使用 1.5 mm 钢板覆盖管口处，以避免损伤并减少掉入逆流凝汽器联箱的焊渣等，如不覆盖，焊渣可能通过管口处掉入联箱。

It has been listed in Torch Plan of 2000 by State Science Committee, the listing code is OOD231D7600709. As a new generation of steel tubes, they have been implemented in more than 100 condensers improvement projects of Hanchuan Power Plant, Victory Power Plant, Baotou First Thermal Power Plant, Datong Second Power Plant, Chongqing Power Plant, Zhongxin 541 Power Plant, Zunyi Power Plant and other plants and achieve great success.

由本公司研制开发的专利产品——高效不锈钢波螺管以其优异的传热性能已经得到了广大用户的认可，并被国家科委列入2000年火炬计划项目，立项批号为OOD231D7600709，成为钢管更新换代产品，在汉川电厂、胜利发电厂、包头第一热电厂、大同第二发电厂、重庆发电厂、中信五四一电厂、遵义电厂等单位的100多台凝汽器改造项目投入使用，并获得成功。

The water chamber takes the shape of tilting cube, in favor of uniform distribution of cooling water on tube plate surface. The tube bundle is divided into two groups of zygomorphy according to the bisection system and it has eight support clapboards. The siphonopore center of each clapboard increases a certain distance corresponding to that of two tube plates and the cooling tube takes the shape of arch. The two-way cooling water of bisection flows through the condenser in opposite direction so as to improve the distribution of heat load for tube bundle. Around the throat of condenser, the final stage low-pressure heater, air extraction tube, intake device of bypass exhaust and the like are deployed.

它的特点是：水室呈倾斜立方体形状，有利于冷却水流在管板面上均匀分布；由于采用对分制，管束相应地分为左、右对称的两组，并且管束设有八块支撑隔板，每块隔板的管孔中心相对于两端管板的管孔中心依次抬高一定的距离，以使冷却管呈拱形状；对分制的两路冷却水以相反方向流过凝汽器，从而改善管束的热负荷分布；在凝汽器喉部布置了末级低压加热器，抽汽管道及旁路排汽接受装置等。

The existing determining method of the optimum vacuum of condenser is only fit for the condition of that condenser is clean in tubes and vacuum system tightness is up to standard or the performance of air ejector is normal.

现有的凝汽器最佳真空的确定方法只适用于凝汽器水侧管壁清洁、汽轮机真空系统严密性正常或抽气设备运行性能正常的工况。

When condensers with carbon steel waterbox and titanium tube structure were protected by SACP in an ocean beach power plant,while seawater were used to be cooling water,carbon steel was under-protected and Titanium was over-protected,because their protective potential are less than-0.85Vvs.

滨海电厂常以天然海水作冷却水，其碳钢水室和钛管凝汽器在实施阴极保护过程中，要求钢电位应低于-0.85Vvs。

In view of the existing problems of the unreasonable steam distribution in condenser, optimal revamp for No.2 turbine low-pressure cylinder air-outlet channel is carried.

潍坊发电厂#汽轮机低压缸的排汽在凝汽器内分布不合理，造成凝汽器换热管热负荷不均匀。

The paper describes the reason why the 1000MW ultra supercritical steam turbine with HP single bypass valve using HP casing start-up was not applied with HP exhaust non-return valve and introduces the methods to prevent over-speed for load rejection,HP casing overtemperature and water admission.

论述了采用高压缸启动方式的带高压一级旁路的1000MW超超临界汽轮机不设高排逆止门的依据及其防止汽轮机甩负荷超速、高缸超温与进水的方法：一是在高压导汽管上加装通风阀，二是在冷再管上加装通往凝汽器的排汽管，三是在冷再管的低位加装能显示水位、自动报警及自动疏水的疏水罐。

The use of brass tubes for the air-cooled zone of a power plant steam condenser can lead to serious corrosion by ammonia,while the application of copper-nickel alloy tubes or titanium ones is associated with expensive costs.

电站凝汽器空冷区采用黄铜管会产生严重氨腐蚀，采用铜镍合金管或钛管则价格昂贵。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
