what do you know about vacuum hot water fired vacuum boilers prices?

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.

Yesterday we learned that the Guangdong Province to increase pollution control efforts by the provincial people's government approval, Guangdong Province Market Supervisory Authority, the ecological environment of Guangdong Province, Guangdong Province, recently issued jointly approved by local standards "fired vacuum boilers price air pollutant emission standards." Compared to the original standard, including contaminant particulate matter, sulfur dioxide, nitrogen oxides, etc. received strict emission limits help to further reduce the total emissions of air pollutants.

Provincial Department of environment-related offices responsible person, the current Guangdong Province "Boiler Air Pollutants Emission Standards" promulgated and implemented more than eight years, with advances in pollution control technology, emission control requirements of its apparent leniency. Meanwhile, Guangdong air pollution control task is arduous, urgent need to close strict standards, further reducing the total emissions of air pollutants.

Guangdong "boiler air emission standards" in the context of the implementation province domain for coal, the material forming the fuel oil, gas and raw fuel 65 tons of steam per hour and less steam boilers, hot water boilers of various capacities and Heat Transfer Material Heater; stoker various capacities, stoker furnace.

The new "boiler air pollutant emission standards" (DB44 / 765-2019) to adjust six major areas.

A clear the raw fuel material forming air pollutants emission limits fuel boiler;

Second, the received strict emission limits boiler air pollutants, increasing the emission limits coal boiler mercury and its compounds;

Third, the abolition of provisions different emission limits by functional area and boiler capacity;

Fourth, in particular an increase of atmospheric pollutant emission limit requirements;

Fifth, increase the fugitive emission control requirements;

Sixth, the excess air ratio conversion flue gas pollutants to the atmosphere of pollutants emission concentration of the reference oxygen content conversion, the oxygen content of the clear reference atmospheric pollutants fired boiler burning biomass.

The new standard in the province gamut execution, the execution time of the specific step-wise: new boiler effect since April 1 this year; the transformation of boilers give some time, depending on which region, from 1 July 2019 2020 or the date of July 1 implementation of the new standards.

Leshan fuel gas vacuum vertical and horizontal hot water fired vacuum boilers price choice for us in the process of vacuum hot water boiler selected, will be exposed to technical doubts. Well, small series with public elaborate. Cost vacuum boiler hot water boiler is mainly composed of the unit cost of a vacuum, burner costs associated accessories (circulation pumps, instrumentation, valve full) the cost thereof. Decided to vacuum hot water boiler cost reasons, there are more important effect of the place: the production of brand differentiation, manufacturers, manufacturing techniques, testing, industrial design, selection of iron and steel and so on. Its interior, the most should pay attention to the following reasons: Ⅰ- productivity producers productive producers of vacuum hot water boiler, largely determine the good and bad of the product. Due, a productive enterprise, remove components on the market more exclusive, we have extensive experience skills. Secondly, and of course, the level of commitment to product design. The size of the level of industrial design standards, a direct impact on the quality of the products is quite large. Affect the future security of the application products, energy conservation sex, sexual fly, and the degree of convenience. The quality of steel selected parameter B- steel, is the cornerstone of their products. Excellent specification standard steel, is to ensure the vacuum seal of the hot water boiler stable utility. Many small factories with non-standard applications or substandard steel, will cause a vacuum hot water boiler products, poor security, high energy costs, and risks exist fly, say users, although that was enough time cost savings, but Suizhudanque. ⑶- automatic production level of manufacturing process vacuum hot water boiler, fuse, coil, fuse, should be the most important skill. These three techniques, the comparison must be to, human operator, using automated manufacturing, the highlight is very obvious. Due to automated manufacturing, with higher reliability, smaller mistakes. This is also a big production of brand vacuum hot water boiler products, far better than an important reason for small-scale production of the brand. Due to its manufacturing and finally, the level closer to the level of industrial design, to achieve a good standard specification set. Some guidelines D- inspection domestic production plants, will not have a lot of time after strict vacuum hot water boiler products, factory link test. Stress test ended, even if the product is excellent. This behavior is certainly not quite fulfill its responsibilities seriously. Excellent test criteria must primarily bear: Stress test test test inert gas, seam welding inspection, the degree of sealing of the test, the relevant section of the trial period. Can be neglected, it can be neglected. Only so, to ensure that users have a good grasp of the product, allowing users to use the process in the future, reduce non-compliant products have caused, directly affect the user's daily production activities. e- repair maintenance of the quality of most of the small factory, there will be no maintenance repair and maintenance. Sale and the entire staff entrusted agent responsible. But most of the agency staff, basically no commitment level team. After the cause of non-compliance will result in delayed, or with consequences often can not handle. In summary, summed up as, because of the cost of vacuum hot water boiler, the direct impact. Generally speaking, good, excellent vacuum product cost hot water boilers, hot water boiler vacuum the unit plus burner, almost, 700KW, 10 million decision.
