The working truth of vacuum hot water boiler:
The
vacuum hot water boiler consists of two parts: the evaporation zone and the
heat exchanger. The evaporation zone is in the lower half of the boiler. It is
a three-way boiler structure; the upper part is a steam-water heat exchanger.
When the vacuum hot water boiler is running, the vacuum pump is used to pump
the boiler first, so that the internal pressure of the boiler is in a state of
vacuum negative pressure, and the air inside the boiler is exhausted by using a
thermal exhaust method.
