Is anti-freezing necessary during the maintenance of winter slurry steam generators?
Thread Content
At temperatures around minus 10 degrees, when cleaning the core of an oil slurry steam generator, is it necessary to use steam to prevent freezing of the equipment casing during the removal of the head?
During disassembly, there is no need to take anti-freezing measures for the shell side.
Yes, the purpose of passing steam through the shell side is to prevent water remaining in the tube side from freezing and damaging the piping. When the temperature is below freezing point, it is necessary to take anti-freezing measures; don’t be careless! After all, the heat exchanger core is expensive, and there’s also a production time involved; this can cause problems if it affects manufacturing.
How is freezing generally prevented, during the pressure release process or after the pressure has been released and the temperature has dropped?
