what do you know about vacuum hot water fuel hot water vacuum 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.
Desuperheaters gas steam fuel hot water vacuum boiler of the role and use of gas steam boiler desuperheater utility with negative pressure combustion process, why not suitable for heating gas steam boiler? This is because the pressure of gas steam boiler is very high, and the requirements of its pipes and accessories is relatively high. So, on this invisible, it will increase costs and expenses. In addition, the installation of a steam boiler is not very simple. Therefore, based on these factors before reaching this conclusion. What is the role of gas steam boiler desuperheater that? Desuperheaters gas steam boiler is generally in the supply pipe, its main role is to reduce the steam temperature, so as to achieve the desired requirements. Desuperheater in kind, type, and the main surface of the two water-jet. For the surface mounting of formula U-tube is a cylindrical tube body, or a recuperative heat exchanger. Water quality which cooling water is no special requirements, mainly in the scope of the low-pressure steam boiler. Gas-fired steam boiler vacuum boiler combustion whether beneficial? If the negative pressure combustion gas steam boiler, specifically refers to a combustion chamber of the boiler, i.e. the furnace, is less than one atmosphere. The means to achieve it, it is achieved by balancing the ventilation system. Pressurized combustion, which does not improve the speed of the combustion gas steam boiler, or to maintain combustion stability. If the conditions are bad, then seal the furnace, combustion positive pressure will increase insecurity, the work environment is unfavorable. Therefore, only the negative pressure combustion to avoid the above problems.
