Waste heat boiler drum
Thread Content
There is a pipe under the steam drum of the waste heat boiler that connects to the inlet of the waste heat boiler economizer; I’m not sure what its function is Could all my friends please help? If you know, let me know!
It should be a circulation tube. To protect the economizer, during startup and shutdown, when little or no water is supplied to the boiler drum, if there are no circulation pipes, the water in the economizer tubes can easily be heated into steam, causing the tubes to overheat and get damaged. A circulation pipe is installed, allowing the heated water to circulate naturally to the boiler drum, and the water in the boiler drum to circulate naturally to the economizer.
Then it’s possible that the deoxygenated water didn’t make it into the deoxygenator, but went directly to the steam drum via a short circuit.
