Structure of the low-pressure steam inlet of the heat exchanger
Thread Content
Why is a portion of the pipe structure at the low-pressure steam inlet of the heat exchanger in the form of a conical tube, and why are guide vanes placed inside that conical tube? Why?
Haven’t seen it. Increase the flow rate to enhance gas-liquid entrainment and prevent gas-liquid separation from causing water hammer.
It is because the pipe ends of the heat exchanger are large while the piping is thin, so an elbow is inserted between them. This is common in heat exchanger piping and has no internal structure.
It’s just a change in the diameter of the interface; what’s inside isn’t a flow guide plate, but rather a shock protection plate designed to reduce erosion and corrosion caused by scouring, and it can also serve as a distribution plate.
Yes, that’s because it’s not possible to install anti-impact plates in the shell side, or there isn’t enough space; so a conical tube is used, with a tube cap inside, to prevent direct impact on the heat exchange tubes.
