Turbine exhaust pressure
Thread Content
The turbine exhaust pressure is high, and the condensate temperature is also high. Does anyone know how to solve this problem?
If the exhaust pressure is high, check the pump to see if the pressure in the wheel housing has increased, and inspect the vacuum system for leaks. The pressure and temperature of the cooling water play a role, as does whether there is any blowing effect, and whether the final-stage nozzles are functioning properly.
Clean it during the surface cooler maintenance.
Inspection items: 1. Has the amount of steam used increased? 2. Have the water pressure and flow rate of the condenser (or air-cooled unit) decreased? ； 3. Has there been any change in the vacuum pumping situation (vacuum pumping system failure, leakage points)?
Hello, we are using a condenser rather than an air cooler, and the condenser was cleaned last December. Could there be any other possible reasons?
We don’t use an air cooler; instead, we use a condenser, which was cleaned last December.
The increase in steam volume is not significant; the water pressure and flow rate in the condenser are normal. After identifying the problem, a backup exhaust pump was switched in, but the pressure still did not decrease. Are there any other possible causes?
All these have been checked, and no abnormalities were found
