Relief valve discharge temperature
Thread Content
Hello everyone. Regarding safety valves, for example, as to how to determine the discharge temperature under fire conditions, is there a corresponding formula for calculation (involving parameters such as operating pressure, operating temperature, and discharge pressure)? I hope everyone will feel free to share their discussions and suggestions so that we can all improve together!
It should equal the saturation temperature at the launch pressure; there are also some other operating conditions that require special consideration.
What was said on the second floor is correct; it should be the saturation temperature of the material under pressure relief conditions.
Temperature before the safety valve at the set pressure. For liquid materials stored in front of the valve, it can be understood as described on the 2nd floor. Each case must be analyzed on its own merits.
In our work, we use the vaporization temperature of the liquid – the bubble point – as the PSV release temperature for the fire scenario
Please share your opinions on the discharge temperature of safety valves under fire conditions, and provide the most authoritative results.
