摘要： 摘要：针对华电国际电力股份有限公司十里泉发电厂凝汽器铜管频繁泄漏、凝汽器背压升高问题，通过对比，选取了管束置换法改造方案。介绍了Tepee排管的特点及改造的具体内容，改造前、后的性能对比试验表明，有效解决了凝结水硬度超标、凝汽器背压升高的问题。凝汽器换型改造后，经济效益明显，投资回收期只有1.79年，极大地提高了设备运行的可靠性。

Abstract: Abstract:In Huadian International Shiliquan Power Plant, the copper pipe of the condenser leaked frequently, and the condenser backpressure was increased. Aiming at above problems, according to the comparison, the reformation scheme of tube bundle displacement was selected. The features of the Tepee tube bank and the concrete reformation items were introduced. The contrast test of the performances before and after reformation shows that the problems of larger condensate hardness and higher condenser backpressure were solved effectively. After the condenser had been remodeled, obvious economic benefit was obtained, the investment payoff period is only 1.79 years, and the reliability of the equipment operation was improved greatly.
