Vacuum hot water boilers are a type of boiler widely used on the market. Its hot water efficiency and thermal insulation properties have been recognized by everyone. Inevitably, some friends ask, is the vacuum hot water boiler really operating in a vacuum environment? How did its name come from?
The vacuum hot water boiler uses the principle of low-pressure boiling water to generate steam, and realizes heat output by steam condensation heat transfer. Inside the unit is a closed vacuum chamber that burns the water in the heat medium and evaporates in the vacuum chamber to produce negative pressure water vapor.
The steam condenses outside the heat exchanger tubes, heating the cold water in the tubes and heating them into the hands of the user. After the water vapor condenses, water droplets are formed and flow back into the heat medium, and the water is heated and evaporated to complete the entire cycle. A vacuum boiler is a hot water boiler. Since the furnace body is a closed negative pressure environment below atmospheric pressure, it is called a vacuum boiler.
Vacuum hot water boilers are a type of boiler that is very popular on the market. It has many applications. Many friends are interested in the structure and function of their principles. The manufacturer will then provide you with detailed information. I hope everyone can increase it. Learn about vacuum hot water boilers.
The lower half of the vacuum boiler consists of a combustion chamber and a heat transfer tube, like a conventional boiler. The lower half is filled with a heat medium, and the upper half is a vacuum chamber in which a U-shaped heat exchanger is inserted. Since the boiler as a whole is under negative pressure, it is very reliable. The heat medium in the furnace does not enter, flow, increase or decrease throughout the operation of the boiler, but is only enclosed in the vacuum chamber of the boiler to transfer heat between the heat transfer tubes of the boiler and the heat exchanger.
The vacuum pressure operation of the vacuum boiler is very reliable. It can be placed on the roof and basement without scaling. long lasting. The vacuum hot water boiler is compared with other hot water boilers. The performance advantage is obvious to everyone, so it will be popular with users.
