凝汽器阻垢除垢的意义及方法探讨

Brief Discussion on the Meaning and Methods of Scale Removal and Scale Inhibition of Condenser

在热力发电厂中凝汽器结垢是一种普遍现象,当垢结积到一定程度后,使凝汽器换热情况减弱,造成汽轮机经济运行受损,增加运行成本,因此,在许多电厂都采用了不同的方法进行阻垢除垢,同时也花费了不少的财力物力。本文对目前一些热力发电厂采用的阻垢除垢的方法进行比较探讨。

Condenser scaling is a common phenomenon in thermal power station. When the fouling accumulates to a certain degree, the condenser heat transfer decreases, and cause damage to turbine economic operation, which will increase operating costs. Thus, many power plants use different methods for scale removal, but also spend a lot of material and financial resources. This paper discusses some scale removal and scale inhibition method that took in some thermal stations.
