Failure Of Low Pressure Heater And Measures

Nov 26, 2016

Troubles and measures
1, steam control steam flow at the entrance of erosion damage.
Adding special protection before the steam inlet tube baffles to distribute steam flow, reduce its impact. 2, heating water heater heats water in the gasification and cause water hammer.
To prevent this behavior, water pressure to be heated should be higher than the heating vapor pressure. 3, non condensed gas holding.
Installed in the heater air outlet pipe should be kept open.
Water supply system Step by step artesian and drain pump circulation equipment difference is there is no drain pump. General plant shaft seal heater directly to the low pressure setting of water (series of different systems are not the same, 125MW, 300MW, say, level 4)
