Can a steam extractor for the Hangqi 6MW unit be used without a drain valve?
Thread Content
In our plant, with the 6MW units operated by Hangzhou Steam Power, the vacuum level dropped from -0.090 to -0.088 after just 2 hours of operation; subsequently, the main exhaust pump was quickly shut down, and the vacuum level returned to -0.090, while the level of water in the hot well increased slightly. I wonder why a secondary hydrophobic system doesn’t have a hydrophobizer installed? Please ask an expert for help! ! !
Level 1 must be installed, while Level 2 can be left uninstalled
We installed U-tubes at the first stage, but no traps at the second stage. So what is the reason? I beg for an explanation?
