Problems existing fuel vacuum boiler agent dealer which a vacuum tube bundle effect bunching effect is widely present in the heat exchanger shell, likewise, vacuum boiler is inevitable. Nusselt proposed an improved condensing heat transfer coefficient formula for 1916. However, due to many differences in bundle properties (heat medium) temperature is saturated, the surface tension outside the refrigerant, the corrected correlation will also be corrected based on experimental results. But again, the bundle effect is still inevitable. 2, it is difficult to maintain the degree of vacuum maintenance and control of the effect of vacuum, vacuum boiler born. When the vacuum boiler stability, the interior portion of the vapor in the vapor space for heat exchange bundle and condensed into a liquid, negative pressure environment part for maintaining a vacuum in the boiler. Theory, boiling and absorbing heat cold water evaporation eventually will be in equilibrium, with the actual amount of heat during operation, the vacuum pump to maintain the boiler typically require external pressure balance, control the heat required to maintain combustion stability of adjusting the water temperature. These external adjustable mechanical means to destroy the balance of the system itself, not only the vacuum boiler system more stable and unstable heat transfer process last longer. 3, exhaust loss if these two exist only in the vacuum boiler, improve energy efficiency research boiler eternal subject. Currently, most vacuum boilers are gas-fired boiler for the boiler, the exhaust gas loss of vacuum insulated with appropriate measures to become a major energy loss.

The advantages of vacuum gas fuel vacuum boiler agent dealer descriptions vacuum gas boiler itself also have more features, vacuum gas boiler matched customers were more interested in updating operations during manufacture. It can be useful for consumers to supply convenience. Well, to start that is that explanation from the people to see the vacuum gas boiler advantage. First, a high level of automation high level of automation vacuum gas boiler itself, based on the consumer's command to complete self-purging and electronic ignition and other operations, in particular, the operation is also reliable and stable, but also the occupation fire-fighting equipment troubleshooting, reduce the hidden dangers caused. Second, the occupation of the provincial natural gas flame spoiler, can improve the heat exchange, greatly reduce heat loss, as consumers save more natural gas, but also consumers, especially in the days of easy operation and does not require the use of with someone on duty, it will save time and save energy. To sum up some of the characteristics of vacuum gas boiler details, after several passes above said, there is no such public facilities and also have more understanding. When, after the selection of heating facilities, intend it can be more.

The principle of a vacuum hot water fuel vacuum boiler agent dealer, hot water boiler works vacuum: a vacuum hot water boiler had already appeared in the early 1970s, first in the finished product is available in Japan. Development of domestic hot water boiler in a vacuum there are some manufacturers in the late 1980s, but due to technical issues, has not been promoted. Now that Japan has more mature models in China has also been a joint venture factory, the author is the choice of a dual-loop vacuum hot water boiler of the plant. The structure of vacuum hot water boiler, by the combustion chamber (furnace), water, vacuum vapor chamber, heat exchanger, heat medium consisting of water or the like. Vacuum state within the body, from the outside air, a sealed state is formed. HTM furnace and covered with water in a sealed tube and within the body, by the pressure of the negative pressure in the steam chamber is maintained below atmospheric pressure, when the heat medium water confined in the inner combustion heating, boiling up immediately, generating heat medium water steam of the same temperature. Steam generated in the machine during the ascent, the contact surface of the heat exchanger is disposed in the negative pressure of the steam chamber, since the water temperature in the heat exchanger is lower than the steam temperature, steam condenses on the heat exchanger surface and release a large heat of vaporization , the water heating heat exchanger, the condensed water under the action of the policy back to the heat medium water again. Accordingly, the heat medium water is constantly "boiling evaporated = = = heat medium condensed water" in a closed loop body. No need to supplement the condensed water, no air burning danger. Water heat exchanger is supplied to the user for heated sanitary hot water and air conditioning. To ensure the reliability of the vacuum hot water boiler operation, the three manufacturers to ensure: 1. In order to ensure a degree of vacuum inside the boiler, at the factory to create a rigorous inspection, the quasi gas leak detection, to ensure that the production process boiler airtight tank. To maintain the degree of vacuum, and to prevent the event, the plant is equipped with a standard suction pump. When the vacuum tank hot water boiler body, the heat medium water is heated to 90 ℃, according to the degree of vacuum exhaust pump automatic operation of the tank, not only the air out of the tank, also the presence of dissolved oxygen in water to remove the heat medium, to keep certain negative pressure, produced inside the tank will not corrode. 2. The heating medium water through a special manufacturing plant impurity, oxygen, water softening treatment, in the production of disposable infusion, can be recycled at runtime, without generally no special filling. I visited the plant in the design of the user survey, a Shanghai Electrical Machinery Plant, 87 years put into operation a vacuum hot water boiler, use a decade overheated media never raise water, which can still work normally. 3. The heat exchanger of the boiler with special requirements, using SUS444 stainless steel tube, which requires a special process during tube processing. 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.

First Affiliated Hospital of Bengbu fully implement the national environmental protection policies, strict screening of clean fuel vacuum boiler agent dealer as the supply of medical supplies disinfection and ward heating equipment. Fast boiler with its focus on research and development of clean-type gas boiler two decades of experience in the industry favored. The partnership, to provide fast boiler First Affiliated Hospital of Bengbu Medical College, a WNS20-1.25-YQ one condensing steam boiler, in terms of design, manufacture, installation and other aspects of strict checks to enhance the thermal efficiency of the boiler as well as truly Energy saving and environmental protection.
