what do you know about vacuum hot water boilers?

1. What is a vacuum hot water boiler? Answer: so-called vacuum hot water boiler, also called vacuum phase change hot water boiler. When the boiler is working normally, the inner medium pressure of the boiler is lower than the atmospheric pressure, and the cold water is heated by phase change heat. Vacuum sealing inside the body of vacuum hot water boiler, negative pressure combustion of heat medium water, steam exchange between steam and heat exchanger, high heat efficiency, one-time treatment and perfusion of heat medium water in factory, no need to replenish water in operation. The unique design of vacuum hot water boiler has formed the characteristics of safety, stability and so on.

2. The composition and structure principle of vacuum Hot Water Boiler? Answer: the furnace body of a vacuum hot water boiler is divided into two parts: the upper part is a vacuum chamber (negative pressure steam chamber), and a tubular steam-water heat exchanger is installed in the space to heat the circulating water flowing through the heat exchanger. Operation principle: during the operation of vacuum hot water boiler, the heat medium water inside the furnace under negative pressure of vacuum absorbs the heat energy released from fuel combustion, boiling vaporizes into low temperature steam, and the low temperature steam rises to meet the system circulating water in stainless steel heat exchanger. Heating circulating water to the user for heating or sanitary hot water. The water vapor itself is cooled and condensed into droplets falling onto the surface of the heat medium and then heated again, thus completing the whole cycle. Heat medium water The cycle of "boiling = evaporation = condensation = heat medium water" is constantly carried out in the enclosed body, so there is no need to replenish condensate water and there is no danger of empty burning. The condensation heat transfer coefficient of steam-water condensation in vacuum hot water boiler is the highest in all heat transfer conditions.

3. What is a vacuum? Answer: vacuum state does not mean absolute pressure is zero, as long as lower than external pressure, can be called "vacuum". For example: vacuum boiler operating inside the shell is debugged as vacuum and maintained between-375pxHg--76mmHg.

4. What is vacuum? A: vacuum refers to the degree of gas rarity in vacuum, usually expressed as "high vacuum" and "low vacuum". High vacuum means good vacuum, low vacuum means poor vacuum. The value of vacuum degree indicates that the actual value of system pressure is lower than that of atmospheric pressure, that is, vacuum degree = atmospheric pressure-absolute pressure. International standard unit of vacuum: Pa (Pa).

5. Why is heat medium water in vacuum hot water boiler heated in vacuum? Answer: the boiling temperature of water is different under different pressures. Under an atmospheric pressure (0.1Mpa), the boiling temperature of water is 100 ℃, while the boiling temperature of water is 4 ℃ under 0.8Kpa pressure. The vacuum hot water boiler works within the pressure range of vacuum degree 2.67Kpa~66.6 Kpa, and the corresponding saturation temperature is 15 ℃ ~ 85 ℃. Therefore, in vacuum, heat medium water is easy to boil and vaporize.

6. The origin of vacuum hot water boiler? A: the basic principle of vacuum hot water boiler was born in 1972 at Zurich University of Technology. In 1975, Japan's TAKUMA Company developed a vacuum hot water boiler on the basis of the principle, which was patented for invention, and was gradually popularized all over the world. This technology has been developed and developed by Korean enterprises, and South Korean TAKUMA, has appeared one after another.

To design environmentally friendly products, what environmental protection boiler boiler host long-running zero fault, thermal efficiency up to 84%, when Sheng Mei reliable hydraulic drive required to heat that started pumping station motors, rose to open the door first place, pushed coal in place after pushing kerosene cylinder return, complete a coal (slag), immediately shutting the door, stop the pump with a time of 20 seconds, fireman worry and effort. Energy-saving, noise-free, natural ventilation technical specifications, without drums, Fan (eliminating the power consumption and acquisition costs), the net efficiency of the boiler high environmental standards, smoke and dust emissions in line with GB13271-2001 standard environmental requirements Class I areas. Indoor heated 24 hours to ensure compliance Heating, fireman just press "boiler instructions" will be a good tune the size of the throttle opening, you can easily reach the innovative "weight off" cleaning door, you can very easily at any time clean tubes inside the product gray, helps maintain high thermal efficiency of the boiler life. A wet slag, the slag cover and seal means ensures that no ash and reliable control of the wind, fireman clean, stable operation "backwater ejector" technology combined circulation boiler water circulation rate up to several times as much as the host to ensure safe operation of the boiler, reliable, as long as the use and maintenance, the service life of up to ten years by "random technical documents" provisions above. Environmental protection boiler widely used in all types of building standards thermostatic heating, central air conditioning, bath and other heating. Supplemented unique supporting the installation, ie fuel "vacuum boiler" as to ensure clean and free of rust bathing water, technical and economic effects are particularly significant high-grade bath, ideal for swimming, yesterday grade hotels, hotels and other heating of the update replacement product of choice.

What are the advantages of vacuum hot water boiler in the heating aspect?

Winter heating has been one of the most important projects in northern China, some of the longer residence time residential district heating boilers generally use pressure or pressure hot water boiler, but most of these boiler systems there are complex, high operating costs, easy scaling, seriously affect the oxidation corrosion and other defects, residential areas, it will bring a lot of adverse effects. In recent years, it is widely favored by vacuum hot water boiler heating industry, and due to its excellent safety performance and minimal footprint and other advantages, is very suitable for building a heat source.
