This paper briefly introduces the serious influence of fouling on the vacuum degree and output of power plant condensers. The principle of automatic fouling of self-rotating plastic ties is described. The simulation test proves that the cleaning fouling ability of autorotation belt is strong enough to meet the cleaning and fouling requirements of heat transfer equipment . Taking the condenser fouling cleaning of power plant steam turbines for example, quantitative analysis of the influence of fouling with different thicknesses on the heat transfer coefficient is given, and an example is given to calculate the high efficiency that can be achieved by using the rotating plastic tie cleaning technology.
