Vacuum chain restaurant vacuum-fired hot water boilers on those points we need to know: we usually refer to the hot water boiler is divided according to different ways, have different classification; wherein if in accordance with the boiler pressure points, then, can be divided into atmospheric hot water boilers, pressure hot water boiler, vacuum hot water boiler; for atmospheric pressure and we may be more understanding, that comparison, for vacuum boiler maybe not so familiar with, then, as far as it relates to the problem, we have to carry out simple doubts, let us better understand its characteristics, uses, etc. 1. What is a vacuum? Divided into physical vacuum and vacuum industrial vacuum two kinds. Physical vapor space means no presence of particles, industrial vacuum pressure refers smaller than a standard atmospheric gas space, refers to the state of the lean gas, usually obtained with a special vacuum pumping machine, the vacuum in the vacuum are industrial boiler vacuum. 2. What is a vacuum hot water boiler? The so-called vacuum boiler, also known as vacuum phase transition boiler. When the normal operation means, the boiler pressure below atmospheric pressure inside the medium, the cold water is heated by the boiler phase change heat mode. 3. What are the key technology of vacuum boiler is? Key technology is the degree of vacuum vacuum boiler to maintain long-term stability, leakage rate is minimal. 4. What is the vacuum hot water boiler heat exchanger the material is? Heat exchanger disposed in the vacuum boiler SUS304 stainless steel tube. The tubing is difficult to furring, high heat transfer efficiency, will not rust, the heat exchange tubes in a more than ordinary quality restrictions, flow rate. The vacuum hot water boiler temperature control temperature control two ways:? Media outlet water temperature control and temperature control. The default for the water temperature control medium. When the water temperature is selected to control the combustion temperature is automatically adjusted with the water, but if the water medium temperature exceeds set limit on the medium water, burner heating was stopped, the water continues to be lower than the medium by the burner outlet temperature regulator when a temperature of 5 degrees limit status. 6. A vacuum boiler safety device which has a safety device for a vacuum boiler:? ① heat medium water temperature control, may control the temperature inside the furnace heat medium water; ② the heat medium water level control, may control the heat medium inside of the furnace body the level of water; ③ the beginning of the pressure, when the abnormal pressure rise within the furnace operation, the combustion is automatically stopped; ④ hot water temperature control, when the over-temperature water temperature, the combustion is automatically stopped; ⑤ destructive protection: explosion-proof valve. When abnormally high pressure furnace, steam furnace body is released to the atmosphere, to ensure that the unit never danger of explosion. 7. What are the main features ① vacuum boiler pressure vessel does not require local authorities to monitor, installation needed to use;? ② do not need to pay, no good water resistance, long life; ③ low energy efficient, operation and management costs; ④ reduce auxiliary, saving investment; ⑤ high safety performance. 8. Why ① vacuum boiler can be small energy radiative heat loss, the furnace is sealed vacuum vessel, itself has good thermal insulation properties; ② high heat exchange efficiency, the furnace body steam - water heat exchanger thermal efficiency is water - water? 10 times the thermal efficiency of the heat exchanger; ③ small thermal inertia: small boiler size, low water heat medium, the heat capacity is small, small thermal inertia and therefore, the reaction is sensitive to load variation. The boiler is turned on, i.e., 5 to 8 minutes with a hot water. ④ heating surface does not scale, energy saving. 9. Why vacuum hot water boiler blast furnace will never work in a vacuum, not a pressure vessel;? Body sealing of certain heat medium water, air will not burn in any state; the body with multiple self-protection device (anti-overheating, freezing, water shortage bit too high anti-pressure, shock, anti-gas fuel supply enough water, etc.). ? 10, vacuum boiler boiler host large investment it though the price is higher than ordinary vacuum hot water boiler, but it can save a lot by vacuum boiler auxiliary equipment investment: plate heat exchanger, a circulating pump, expansion tank soft water treatment equipment and so on, can also be save the corresponding pipeline installation fees, accommodation fees auxiliary power system control fees, investment is still lower than the average integrated hot water boiler system.

Characteristics of different types of vacuum vacuum phase transition phase transition boiler fuel boiler according to the classification method is the most important, this approach allows people to buy the right. With the increase in the degree of industrialization and deepen people's needs, vacuum phase transition boilers in the market accounted for an increasing share of different types of boilers vacuum phase transition characteristics determine the most suitable location for it. Based on this situation, we should understand its classification and a variety of other features to facilitate proper purchase. Here we will tell you different types of vacuum phase transition characteristics of the boiler. Vacuum phase transition boilers and boiler can be called a vacuum, it works and focus on the vacuum phase transition. The fuel can be divided into four categories, but may be three and wherein a category is thus divided into the following two categories, and describes the characteristics of the major categories. When (a) an electrically heated vacuum heating boilers vacuum phase transition phase transition into the operating electric boiler, inside a vacuum environment. At this time, the intermediate medium oxygen in water will be discharged to the outside electric boilers vacuum phase transition, and therefore does not cause oxidation corrosion in the boiler, cause damage to the device. Meanwhile, vacuum chain restaurant vacuum-fired hot water boilers heating heat exchanger portion of the material used is stainless steel, corrosion will not occur. Further, the electric vacuum hot water boiler only once was added a small amount of the heat medium water, increase nor decrease is running, the internal no scaling. (B) Such a phase change in vacuo fuel (gas / coal) boilers vacuum phase transition is the import burner, its high combustion efficiency, low noise and exhaust emissions. Internal exchanger made of stainless steel, in this regard to ensure high heat transfer efficiency, on the other hand can ensure a clean water quality. At the same time, its smoke tube interior spiral spoiler, in order to improve heat transfer efficiency, and lower operating costs. Further, it is the overall use of square configuration, the boiler and the heat exchanger is a one-piece design, so that a small volume of its structure compact shape the United States. On the face of vacuum phase transition boiler rough classification, and describes the different categories with the characteristics, so that we can be aware of their knowledge. This knowledge is part of the basics when buying a vacuum phase transition boiler, we need to keep in mind, so that in the selection of purchase, to make the most appropriate choice, to choose the most desirable machine.
