Operating principle of vacuum atmosphere furnace

Vacuum atmosphere furnace is used for heating equipment in vacuum environment, mainly used for ceramic firing, vacuum refining, electric vacuum parts degassing, annealing, metal parts brazing, and ceramic - metal sealing.

The vacuum atmosphere furnace forms a vacuum environment of negative pressure inside the closed furnace body, and fills the body with heat medium water. The heat medium water is heated by combustion or other means, and then the heat medium water evaporates - condenses to the heat exchanger, and then the heat exchanger heats the water that needs to be heated.

Vacuum atmosphere furnace body is divided into two parts; The upper part is a vacuum chamber (negative pressure steam chamber), in which a tubular steam-water heat exchanger is installed to heat the circulating water flowing through the heat exchanger.

Operating principle of vacuum atmosphere furnace: When the vacuum hot water boiler is running, the heat medium water in the furnace body absorbs the heat energy released by the fuel combustion under vacuum negative pressure, boils into low-temperature steam, and the low-temperature steam rises to meet the system circulating water in the stainless steel heat exchanger, and the heating circulating water is sent to the user for heating or sanitary hot water. The water vapor itself is cooled and condensed into water droplets, which fall to the surface of the hot medium and are heated again, thus completing the whole cycle.
