The overall structure of vacuum furnace

Vacuum tempering furnace furnace The body consists of two parts; The upper part of the vacuum chamber (negative pressure steam room), hold the space tubular steam-water heat exchangers, used to heat flow through the circulating water heat exchanger. Operating principle: the vacuum hot water boiler is running, under vacuum negative pressure furnace absorbed heat medium water inside the fuel combustion heat release, boiling vaporization for low temperature steam, low temperature steam rising in stainless steel heat exchanger in circulating water system, circulating water heating for the user or sanitary hot water for heating. Itself is cooled water vapor condenses into water droplets fall to the heat medium water again after heated, so as to complete the whole cycle.
So it is the working principle of the interior of the vacuum furnace. HTM constantly in an enclosed body = = = = evaporation condensation = = "boiling heat medium water" in the loop, so don't need to supplement the condensed water, also do not have empty the risk of burning. Vacuum hot water boiler using soda condensation heat transfer, in all working condition of heat transfer, soda, condensation heat transfer coefficient of heat transfer is the highest.
