How Does A Vacuum Hot Water Boiler Work


A vacuum hot water boiler because of its small size, high thermal efficiency, the system is simple, reliable, stable operation, high security features, making the gas fired vacuum boiler has been more and more use, especially in civil heating field to meet the increased demand for hot water. In this article, we will get know of how does a vacuum hot water boiler work.

Vacuum hot water boiler work principle

Vacuum hot water boiler structure is determined by the combustion chamber, water pipes, vacuum steam room, heat exchangers, hot water and other components of the media. A vacuum state inside the body, isolated from the outside air, to form a closed state. The heat transfer medium covered with water and airtight stove and water pipes inside the body, due to the negative pressure steam chamber pressure was maintained at atmospheric pressure under heat medium, including when sealed combustion heating water immediately after boiling up, generating heat medium water same temperature steam.
The steam generated inside the rising process, the contact to the configuration of the heat exchanger in the negative pressure surface of the steam chamber, since the heat exchanger temperature is lower than the steam temperature, the steam will be condensed on the heat exchanger surfaces and emit a lot of heat of vaporization heating the water in the heat exchanger, condensate role in the policy again back heat transfer medium water.
Therefore, the heat medium water continuously in a closed machine body engaged in “Boiling — evaporation — condensation — heat medium water” cycle. No added condensate, and no danger of air burning. The water is heated in the heat exchanger after the delivery to the user for air conditioning and sanitary hot water.
