Degassing of heating water

摘要

The pressure in the pressure vessel (1) is lowered by cooling of the heating water in it. The heat released from the heating water is used to heat up the heating water outside the vessel. The pressure vessel containing the heating water is cooled down by the use of circulating air. The pressure vessel is installed in a heating water tank (2) which is connected to the heating system by at least one heating water pipe (21).
