Vacuum boiler parameters

The vacuum boiler parameters include rated heat supply 1.75MW, outlet water temperature 60°C, return water temperature 50°C, and rated working pressure -0.02MPa.

A 350kw vacuum hot water boiler with an outlet water temperature of 60°C and a return water temperature of 50°C is what we often call a half-ton gas-fired vacuum hot water boiler. Under full load operation, it can produce 300,000 kcal per hour. heat. This boiler is a boiler that operates under negative pressure and has high safety. It is widely used in hotels, guesthouses, bathing centers, schools, hospitals and other places.

The 350kw gas-fired vacuum hot water boiler with a rated working pressure of -0.02MPa uses water to boil in a vacuum state to generate low-temperature steam, and then heats the system circulating water through steam condensation and heat exchange, and finally meets the requirements Boiler equipment for hot water required. It can be configured with multiple heat exchangers and can supply hot water of different temperatures and uses to meet the different needs of customers.

Structure of vacuum boiler

Vacuum boiler The lower half of the vacuum hot water boiler has the same structure as an ordinary boiler, consisting of a combustion chamber and a heat transfer tube; its lower half is equipped with a heat transfer tube. medium, the upper part is a vacuum chamber in which a U-shaped heat exchanger is inserted. Since the entire boiler is under negative pressure, it is absolutely safe. The heat medium in the furnace does not enter, exit, increase or decrease during the entire operation of the boiler. It is only enclosed in the vacuum chamber of the boiler and transfers heat between the heat transfer tubes and heat exchangers of the boiler.

The heat medium in the furnace is completely deoxygenated pure water, which is non-corrosive and free of scale, making the boiler have a service life of more than 20 years. To sum up, the natural development trend of boilers with such performance is to replace traditional drum-type and shell-type boilers; the replacement rate in Japan is as high as over 85%, and in South Korea it has reached over 43%.
