In the design of vacuum hot water boiler, the problem should be noted that the heat medium water vacuum hot water boiler, the negative pressure conditions at the maximum temperature is about 93 deg.] C, the maximum temperature of the boiler water at about 80 ℃, the water temperature and therefore require more when high, the water temperature should be used in other types of high boiler; 2) vacuum hot water boiler heat exchanger tube diameter is small, generally about 10 ~, while not fouling the inner pipe, to prevent impurities clogging the tube system , other sources should be installed or filter before the boiler return pipe inlet; 3) vacuum hot water boiler design, according to the system pressure, the pressure parameter determining unit, to ensure that the working pressure of the pressure unit to meet the system requirements. Pressure relief valve is provided at the interface of the vacuum hot water boiler system should be designed in which the unit set pressure must be less than the maximum allowable pressure, the pressure relief valve unit and the valve shall be fitted to the connecting portion based on such a design configuration of the vacuum hot water boiler , as compared with the vacuum hot water boiler pressure hot water boiler, has its own unique advantages, table 1 Comparative characteristic of both systems were schemes.
Select vacuum boiler quality four reasons for people's lives improve, they also contributed to the gradual increase of the number of required hot water, a common boiler maintenance is more troublesome because it uses large tonnage; therefore, in this case, a boiler launched a new trend that is creating a vacuum boiler, it is called the new trend in the field of civil heating, and favored by the users as well as national attention. So why are more and more users will choose to vacuum boiler it? This is mainly for the following four reasons: 1, safe and reliable operation of the boiler during operation when the vacuum pressure inside it remains under vacuum. Regardless of the heat exchanger in the boiler due to external pressure leaks, because the operation or failure can not exceed the atmospheric pressure at the outside, its various vacuum pressure switch, will automatically cut the power supply. Moreover, the stable performance of the vacuum boiler also has advanced technology, the failure of all automatic water level, low voice alarm system can automatically cut the power supply and inform the user, to avoid great losses because of excessive water caused. 2, the structure is compact and easy to install by vacuum boiler structured design, easy to transport and make the product, because of the small volume of the unit, in a small space so that multiple units can be used in parallel but it also has unique environmental features. 3, vacuum boiler applicability due to the special design of the structure is formed, may be provided at the same time hot water and the temperature difference between the multiplexer to satisfy their demands for hot water supply. And continued insulation effect is obvious, the burner is also the use of imported products, especially for low-lying areas. And from commissioning to run the whole process does not need to check, of course, does not require the holder of the Boilermakers. 4, because of its long life vacuum boiler interior is integrally sealed atmosphere, and at runtime, the intermediate oxygen precipitation medium is water, and promptly discharging furnace, the furnace so long oxygen corrosion does not occur, nor will place a long time to generate internal boiler fouling difficult to clean, thereby increasing the life of the boiler use. It is because of a variety of vacuum boiler has so many features, making it more smoothly during operation, and operator can be more time-saving, so it can be widely used in so many places, is not close there are structural aspects of the advantages of using a full-featured, in order to gain certain advantages in various industries.
(2) fuel (gas ) vacuum phase change boilers, such as vacuum phase change boilers, adopt imported burners, which have high combustion efficiency, low noise and exhaust gas emissions. Internal use of stainless steel exchanger, on the one hand to ensure high heat transfer efficiency, on the other hand, to ensure clean water quality. At the same time, the smoke tube is equipped with spiral spoiler to improve the heat transfer efficiency and reduce the operation cost. In addition, it adopts a square structure, boiler and heat exchanger designed as one, making its structure compact and small shape beauty. Through the above classification of vacuum phase change boilers, and the description of the different types of The characteristics, so that everyone to its relevant knowledge to achieve a number of.
