1. What is a vacuum? Divided into physical vacuum and vacuum industrial vacuum. Vacuum means that no physical space of any particle. Industrial vacuum means a pressure lower than the atmospheric gas space standard. It refers to a thin gas state. It is usually obtained by a special pump. Vacuum vacuum boilers are industrial vacuum.
2. What are vacuum hot water boiler? Vacuum boiler is a vacuum environment, the sealed furnace body negative pressure, so that the furnace body is filled with heating medium water. The heating medium water heated by burning or otherwise, and then evaporated by the heat medium and condensed water into a heat exchanger, then heating the water to be heated by the heat medium water. Vacuum heat boiler indicated: oil, gas, natural gas, natural gas, electricity -> combustion (heat conversion)> heat medium water -> steam condensation heat after boiling -> heat -> Heat Conduction -> vacuum boiler water working principle: the use of water at low pressure characteristics of a low boiling point, rapid heating of the heat medium water sealed furnace body, the heat medium temperature steam generated by the boiling water, the steam condenses on the heat transfer tubes within the heat transfer tubes heating the cold water, to supply hot water purposes. Vacuum boiling point of water and the corresponding table: structural diagram of the degree of vacuum (Kpa) 0-31-54-70-81-89-94-97-99-101 boiling point of water (℃) 10090807060504030200 vacuum hot water boiler:
Ensure gas boiler can maintain a stable long-term working condition of the gas boiler is one of the more common applications in industrial production equipment, many are relied on to solve the water problem, in order to ensure long-term gas boiler can maintain a stable working condition of the boiler proper maintenance is essential to go. If the gas boiler in the past has been shut down for a long time, how to restore normal? The first is the gas boiler thoroughly cleaned, since when not used for a long time, then gas boiler from inside to outside is bound to accumulate a lot of dust, only to be cleaned before you can use a clean, clear to check out the actual condition of the boiler . After completion of the gas boiler cleaning, be sure to use hot air to dry them, but not both for heating the furnace walls and other accessories, this is likely to have adverse consequences. Right way is to place an electric heater in the bottom of the gas boiler, heated. When the gas boiler has just put into use when the need to place the desiccant should also pay attention to corrosion on the tray, the tray holding good drying effect, contribute to its normal use, so as to promote the effectiveness of its full potential gas boiler. In addition to long pauses use of gas-fired boilers to note the above operations, the daily maintenance is also very important and must be inspected once every few months we should note that the desiccant, promptly added; and each periodic inspection of boiler parts usage, have something to damage should be repaired or replaced. On this basis, gas boiler to regain the good performance to the previous, to provide the necessary heat for industrial production, its value can be fully tapped. What should you watch gas boiler feed water? Gas boiler water quality requirements, boiler water hardness is too high if the site should be supporting the hardness of the water treatment, water treatment package of softened water can reduce scaling in the boiler tubes, thereby enhancing the life of the boiler to reduce operating costs. Sheung Shui time should slowly add water to the inside steam boilers, water temperature is not too high. Add water, not too much, as the temperature of the water will continue to increase expansion, resulting in waste. Generally, add water to the normal water level of the water line also is the middle line on it, now supporting the boiler above all intelligent devices in Sheung Shui, simply open the smart addition of water it can be had. To put inside the boiler economizer and air inside the boiler duct excluded when water was added. Hot boiler water treatment equipment must go through a thermal efficiency of the process water boiler is very high, can be quickly heated, and there is no dust, of course, no smoke is generated, so that the surrounding environment will not be made cause any harm. Hot water boiler operation is very simple, he has a very novel appearance, this novel shape can play a decorative role, then there is the structure of the wns fire tube vacuum hot water boiler for hospital is also very unique. Hot water boiler water must be processed through water treatment equipment, there is no reliable water treatment measures, water quality testing, boilers are not allowed to put into operation. Evaporation rated greater than or equal 1T / h of steam boilers and thermal power is greater than or equal to the rated boiler hot water boiler should be set 0.7MW sampling device, when the quality requirements of the steam, the steam is also provided the sampling device. Water quality testing for not less than once every two hours, and do a good job records, water quality laboratory abnormalities should take appropriate measures to increase the number of tests. Evaporation rated greater than or equal 6T / h boiler deaerator device should be configured. Hot water boiler is a thermal energy released by the fuel combustion to heat the water in the vessel, the temperature of the water reaches the desired (hot water) of the heating equipment. It is a whole consisting of boiler accessories instrumentation and ancillary equipment. While the boiler furnace and boiler in two portions, after the raw water into the boiler, the boiler heating surface of the heat transferred to the water absorption, the water heated to a certain temperature to heating using user productivity. Continuous fuel combustion burner constantly emit heat, high temperature flue gas produced by combustion heat propagation, can transfer heat to the heating surface of the boiler, while the temperature was gradually lowered itself, and finally through the chimney. Pot and furnace division of work, a endothermic, exothermic, perfect fit is closely linked to the device as a whole, are indispensable. Hot water boiler in operation by the circulating pump for power. The aqueous continuous circulating flow, stop the heat absorbing heat receiving surface to transfer all the raw water, the heated surface to give good cooling, heating water accelerated the foot, thus ensuring the safety of the boiler heating surface under high temperature conditions jobs. To ensure the quality and safety of the boiler, be sure to choose a regular gas boiler over hot water boiler manufacturers, so the quality can be guaranteed, in order to have service guarantee.
Because the inside of the furnace is a vacuum, the heat medium condenses onto the heat exchanger after it is heated and evaporated, so the heating medium is no more than the heating medium in the process of use. At the same time, it is more energy-saving and environmental-friendly than other types of boilers. Do you know what are the main advantages of the most reliable vacuum boiler? Here is a brief introduction to the advantages of vacuum boilers.
1, high efficiency and energy saving because the vacuum negative pressure hot water technology is used in the production design of the vacuum boiler, so it can make the boiler run in the vacuum state, and its boiling point is low, and it can carry on the latent heat exchange of vaporization (condensation latent heat). And using the three-way wet back design, the heat transfer performance is good and can effectively improve the radiation and convection heat transfer area, so it is more efficient and energy-saving.
2, multi-purpose because vacuum boilers are not only divided into vertical, horizontal, fuel and gas and many other models that are freely available to the user, but also because its heat exchanger and header are a separate state. Therefore, the load of heating water and hot water can be switched at any time according to the actual needs, which can fully meet the different requirements of users for heating water and clean hot water, and ensure that hot water is clean and stable so as to realize multi-use of one machine.
3, the installation is simple because the vacuum boiler is manufactured with modular design and high-performance heat transfer components, so the unit size of the boiler is smaller. It is not only convenient for transportation and storage, but also simpler and more convenient in installation method. In addition, it can also be conveniently installed in a small space or can be used in parallel operation of multiple units according to the actual needs. These three parts are the main advantages of vacuum boilers.
