What are the characteristics of vacuum boilers?

Vacuum phase change boilers in the industry are usually referred to as vacuum boilers. Professional vacuum boilers form a negative pressure vacuum environment within the enclosed furnace body. There is no danger of expansion and explosion because a vacuum boiler creates a low-pressure environment with little air, and then uses water to boil at a low temperature to produce steam. As a result, it is now commonly used in higher elevations. Let's find out what the features of the vacuum boiler are.

1, the vacuum boiler will not corrode because the internal structure of the vacuum boiler is negative pressure vacuum state, so it is completely isolated from the atmospheric pressure, so the pump pumps configured by the various units of the boiler will continuously discharge the steam from the unit. It does not corrode the internal structure, so vacuum phase change boilers perform fairly well in terms of durability.

2, safety and reliability are different from ordinary atmospheric pressure boilers. Because vacuum boilers pump air out of the inner container to form a vacuum environment, the furnace body does not work under the vacuum body in the course of use and will not be expanded by heat. It is not a pressure vessel, so there is no risk of explosion. At the same time, if the pressure increases due to faults or other perceived factors, the vacuum pressure switch automatically cuts off the power supply, so vacuum boilers are more reliable than other types of boilers in terms of safety.

Note 7 mw vacuum hot water boiler vacuum boiler running what is the formation of a negative pressure in the vacuum environment inside a closed furnace, widely used in hotels, residential, commercial applications such as heating, sanitary hot water heating, and other fields. Since the inner pressure when the furnace is always working in a vacuum, and so the higher heat exchange efficiency. At the same time, the unique design of the vacuum boiler safer. During use, if the pressure exceeds the external atmosphere, the unit will automatically cut off power, when the water level will fail alarm. In order to better protect the boiler, ensure that the boiler safety, should pay attention to the following aspects: caveats vacuum hot water boiler 1, before each run vacuum boiler boiler gas pressure conditions must be checked to ensure that pressure is normal if you have to pay attention to water pressure can only keep a small fire, because the fire under the pressure of six thousand mpa run stagnation pressure may be due to lack of time - 6000 mpa. 2, when using the vacuum boiler, water is also noted that the heat medium and the home heating medium water pressure and temperature, and to ensure that the pipeline valve is opened to prevent any valve out of the water heat exchanger branches off, because the resulting expansion E principle and the principle of thermal expansion will shrink far more than the quota. Determine the scope of work, resulting in an explosion, resulting in serious accidents boiler scrapped. 3, vacuum boilers in all normal operating conditions, we must first pay attention to the normal operation of the pump, carefully observe the vacuum pump outlet pressure and sound, and then open the boiler control power in the case of confirming that no abnormal operation. Be careful not to turn off the power of the vacuum pump. 4, when the vacuum boiler operation, to be noted that the parameters set on the sensor screen to ensure that the water temperature of the boiler, an outlet temperature control, control of the temperature difference between the flame and the conversion temperature can meet application requirements.

Exhaust gas has been plagued by sewage paper industry, paper industry pollution problems of the country very seriously. Fujian Heng paper packaging company has been committed to the use of clean-type boiler paper processing. October 22, 2016, David Carse, the paper with my company, signed a 6 tons of steam an integral condensing steam boiler for the production of corrugated cardboard and other paper products. I provided the boiler greatly solve the problem of sewage wastewater Heng paper. After the boiler operation, both to meet local environmental requirements, but also reduce operating costs for the constant boiler paper products.
