Vessel pressure relief valve for slurry gasification; the vessel punching valve suffers from cavitation due to the large pressure difference before and after (6.0 MPa)
Thread Content
For the lockhopper pressure relief valves used in water-coal slurry gasification, these valves are often damaged due to cavitation caused by the large pressure difference before and after them (6.0 MPa). What are some solutions? How to overcome cavitation under such a high pressure difference?

Reply to 4# liyijun19681003: I’m not sure which type of four-stage pressure reduction method you guys are using. In some designs, pressure relief valves are employed, and pipelines as well as flow control orifice plates are taken into consideration. Could you let me know which pressure reduction method is being used?
