Leakage in the heat exchanger heated by steam
Thread Content
There is a leak in one of the heat exchangers in the unit; steam at 3.5 Mpa is used to heat the acidic gas, and this steam leaks into the acidic gas. The temperature of the steam at 3.5 Mpa is around 280 degrees. If the amount of steam leaking is 2 tons per hour, is the temperature of the steam that leaks into the acidic gas also around 280 degrees? Does the temperature of steam at 3.5 Mpa not change depending on the flow rate? Thank you; I would appreciate it if an expert could answer this question. I’m willing to offer a generous reward
The temperature of the steam that leaks into the acidic gas is also around 280 degrees. The steam temperature at 3.5 Mpa does not change with flow rate. It is recommended to repair the heat exchanger as soon as possible; the leakage must not be allowed to persist.
Since the vapor pressure of the steam that leaks into the acidic gas decreases, doesn’t the temperature of the steam also decrease?
The leakage rate is 2 t/h, which is quite high.
If the leakage is 0.2 tons per hour, is the temperature of the leaking steam also around 280 degrees?
After a leak, the pressure will drop and the temperature will decrease.
What’s the point of asking this? Fix the heat exchanger right away; acidic gases can also penetrate to the steam side. Check your steam condensate as well.
