(2)透平排汽溫度降低,真空度上升。防垢器安裝后,透平真空度一直維持在0.085～0.087MPa范圍內,與安裝前相比,抽汽量不變,盡管透平排汽量增大,但排氣溫度平均下降了10℃,真空度上升了0.015MPa。

4. 結語

超聲波除垢具有既能防止積垢的形成,又能破壞已有積垢的雙重作用。超聲技術在石油化工等領域中的成功運用,可提高產品質量,保障生產和設備的安全運行,降低成本,提高生產效率[8]。超聲波防除積垢技術操作簡單、成本低,是今后電力行業防除積垢技術的發展方向。

Abstract

In this paper, starting from the point “energy-saving and cost-reducing”, an overview of the seriousnessand the economic losses caused by power plant fouling are carried out. The paper investigates themechanism and the benefits of ultrasonic used in cleaning fouling, as well as its application in powerplant heat exchangers. It is possible to come to the conclusions that ultrasonic cleaning is the rightdirection of cleaning fouling technology development in the future, but also fouling control technologyin power industry.
Keywords: ultrasonic; scaling; heat exchanger; application
