    Operation of vacuum oil quenching furnace

    Release date: 2013-09-17 00:00 source: http://www.coberturaguaruja.com Click:

    When the non condensable gas is produced in the vacuum oil quenching furnace, the pressure will rise accordingly, that is to say, the vacuum degree will be destroyed. The effect of the non condensable gas produced in the vacuum oil quenching furnace on the heat transfer efficiency is very serious. When the volume content of the non condensable gas reaches 0.2%, the thermal efficiency will be reduced by 20-30%, the outlet water temperature will not be increased, and the boiler output will be reduced. Therefore, when the vacuum oil quenching furnace is running, the non condensable gas must be pumped out.
