commercial 200 bhp vacuum hot water boiler

Sources of air and air vapor hazards of what? Air and non-condensable source gas: after a boiler shut down, a vacuum generating suction air; feed water into the boiler; feed water and condensate in the intake air is exposed to the atmosphere. Air hazards: there is an air steam heating system, not only can cause corrosion of pipes and equipment, but also reduce the heat transfer performance of heating equipment, the impact of condensate recovery, resulting in waste of energy.

what do you know about commercial 200 bhp 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.

The high price vacuum boiler efficiency gas boiler: commercial 200 bhp vacuum hot water boiler with three return structure, a unique wet combustion chamber structure back to back, so that the heat loss down to the limit unit, the whole thermal efficiency of 92% or more.

The company set up production bases in Qiandao Lake in Zhejiang, Jilin Changbai Mountain, Danjiangkou, Hubei, Guangdong Evergreen Lake, Baoji Taibai Mountain, Xinjiang Tianshan Manas, Emei Mountain in Sichuan and Guizhou Wuling Mountain Eight high-quality natural source of drinking water, all the water sources in the production process complete, with practical action to practice the "we do not produce water, we just nature's porter," the corporate mission. 2017, party fast one condensing steam boiler Nongfu Spring Co., Ltd. won the bid for procurement, stationed in the factory, the production of drinking water to help hand. The winning bid farmer spring production base, covers an area of ​​about 60,000 square meters, with an annual output of 140 million bottles of fruit juice drinks and 180 million bottles of drinking natural water production line.
