Pressure setting standard for boiler safety valves
Thread Content
The design pressure of the boiler in our facility is 1.25 MPa. It turns out that the pressure of steam used in production is 0.8 MPa. The set operating pressure for the safety valve of the boiler is 1.05 MPa, while its tripping pressure is 1.08 MPa. Currently, the pressure of steam used in production is 1.0 MPa. May I ask experts what setting would be appropriate for the safety valve at this point? Thank you! ! ! :handshake
According to Article 141 of the \"Regulations on Safety Inspection of Steam Boilers,\" for boilers with a rated pressure of 1.25 MPa, if the operating pressure is 1.0 MPa (in the case of boilers without superheaters), then the setting pressures for the boiler safety valves should be 1.04 MPa and 1.06 MPa. The setting pressures of the safety valves are adjusted based on the actual operating pressure.
