Analysis of the reasons for the decrease in vacuum level in the turbine air cooler?
Thread Content
As the title suggests, there are various reasons for a decrease in the vacuum level of a turbine air cooler; these include flange leaks, insufficient cooling capacity, and pump failures, among others. Please analyze it – are there any other reasons?
Improper control of the surface cooler liquid level leads to inadequate cooling
①Insufficient circulating water volume, rising water temperature, or interruption in the circulating water flow. ②The power steam pressure of the ejector drops or the steam supply is interrupted. ③Fluctuations in the condenser liquid level (too high or too low). ④Scaling on the condenser tubes reduces heat exchange efficiency. ⑤The condensate pump has insufficient displacement and is not operating properly. ⑥The main injector is blocked. ⑦The vacuum system has obvious leaks.
