automatic vacuum hot water boiler

The advantage vacuum boiler of vacuum boiler is also called negative pressure boiler. The thermal dielectric water of vacuum boiler is high purity water which is deoxidized and descaled and sealed into vacuum chamber. Multiple sets of heat exchangers can be arranged on the upper part of the boiler main body to achieve multiple loops and bear different system pressures. Vacuum boilers do not need to be equipped with plate heat exchangers and volumetric heat exchangers. The heat transfer mode between hot water and cold water in this machine is steam-water condensation heat transfer. The heat transfer coefficient is 4000~4500kcal / m ~ 2 ·℃, which is higher than that of pressure boiler. 50-450kcal / m2 ·℃. More than 10 times. Therefore, the thermal efficiency of the ordinary vacuum boiler can reach over 94%, and because the vacuum medium of the vacuum boiler is not connected with the external atmosphere, the problems of oxygen corrosion and scaling are completely solved, and the service life is long. Vacuum boilers can last up to 20 years or more. Gas-fired boilers in northern residential areas usually use atmospheric or hot water boilers for heating. However, due to its complex system, high operating cost and high risk of scaling and oxygen corrosion, the practical application is less and less. In recent years, the automatic vacuum hot water boiler is getting more and more The more widely used, and because of their excellent safety and pressure heating, they are very suitable for building heat source. The main advantages of vacuum boiler are: there is no explosion danger under negative pressure operation; because of small heat capacity, short heating time, small start-stop heat loss and high actual heat efficiency, the heat transfer of the body not only realizes the pressure operation of the heating system. Moreover, the heat loss of the heat exchanger and the power consumption of the pump are avoided. Compared with the indirect heating system of the boiler heat exchanger, the investment and land area are greatly saved, and the boiler body has a long service life in the closing operation.

Which models the steam boiler steam boiler are generally divided by pressure, not by dividing the vapor temperature, and pressure divided by the water vapor temperature is different matches, the matching relation to particular listed below: a general boiler pressure: less than 3.8 MW, two 450 degrees, the high pressure in the boiler: 9.8 MPa or less, 510 to 540 degrees three, an extra high pressure boiler: 13.7 MPa, 555 degrees is less than four, subcritical boiler pressure greater than 16.7 MPa, 555-570 ℃ Xuchang picking vacuum gas boiler note things are what some of the gas-fired boilers | oil-fired boilers | steam boiler environmental equipment Co., a lot of users when picking vacuum gas boiler, because there is no way, often do not know how to sell. Because a lot of series of vacuum gas boiler, not the same layout, different manufacturers, most people do not know by what means of picking, and later continued to teach you their pick of some small knowledge. First, pick the right vacuum gas boiler, we must understand the layout of the vacuum gas boiler, which should set up the equipment debugging in the selection, which should also check and maintenance, and therefore the normal layout must be appropriate to initiate. Secondly, each vacuum gas steam boiler pressure part of the money to have, but when we choose has spent part of this unit which should be picked when the gas boiler series vacuum pay more attention to the needs of another good summary be picking. And then, equally importantly vacuum gas boiler equipment have used a lot, there is a good part complementary efficacy, cost reduction can be more good savings. Therefore, in the days of picking vacuum gas boiler, summary said earlier this something we must pay more attention to, so to be able to pick the right product, good operating more good choice.

In early November, the annual "Technology Innovation Award" announced by the Chinese Ministry of Science and Technology Venture Association. Fast Boiler Co., Ltd. With strong R & D strength and strong R & D hardware infrastructure was awarded The "Technology Innovation Award (business)," the honorary title.

In the use of vacuum gas boiler, need to understand what matters vacuum gas boiler also needs to complete its operation in accordance with the guidelines in the use of gas boiler using a vacuum today's increasingly wide following for us to come together to figure out the vacuum gas boiler in the selection as are those who need to understand the summary. First, employees need to understand the use of vacuum gas boiler quality employees use vacuum gas boiler need for quality vacuum gas boiler outstanding figure out, and I too understand the safety rules that are part of the employee does not belong to the unit is not operating, on the way transfer classes also need to do the transfer of records. Second, the gas detection engine vacuum boiler needs to be done before launching also detected in various fields, for example, looked at gas load value is not normal, vacuum gas boiler is not possible through routine gas, followed by the pump is not in normal use, etc., these are all employees need to use the contents of the intentions of detection. If the use of employees exposed to failure, also need to reach accurate disposal, failing that can easily lead to serious danger, the company's employees can also use time and counseling to improve the professionalism of the staff in the use of vacuum gas boiler start.
