horizontal vacuum hot water boiler
Fast boiler was informed that Harbin City People's Government Office recently issued a "Harbin in 2019 to win the Battle of Blue Sky embodiment" (hereinafter referred to as "Notice"), referred to "notice" to implement the transformation of ultra-low emissions , with the transformation of the coal power plant conditions and the conditions of the urban built-up areas and over 65 tons of steam coal-fired boilers basically soot (particulate matter) ultra-low emission, all of the conditions of the energy saving and ultra-low emissions (particulate matter, sulfur dioxide, nitrogen oxide), substantially gas boiler low NOx combustion technologies. In particular implementation the conditions do not have emission limits, preferred embodiment of the grid or switch to clean energy. Increase Condensing units and cogeneration units technological transformation efforts, speed up the heating pipe network construction, improve the heating capacity and the full release. Cogeneration area does not have central heating conditions, the existing multiple small coal-fired boilers, to replace the principle of construction of large-capacity coal-fired boilers in accordance with the same volume.
Since January 1, 2019, the full implementation of thermal power plants and boilers in particular air pollutants emission limits. The development of industrial furnaces comprehensive remediation plan, establish management classification list. Carry iron and steel, building materials, thermal power and other key industries and fugitive emissions of coal-fired boilers investigation, the establishment of management accounting.
Good implementation of ultra-low emission coal-fired plants green electricity, coal-fired boiler out of grant funds to develop policy, research and comprehensive utilization of straw Jinshao, out of old cars, coal-fired boilers ultra-low emissions and energy efficient building renovation and other key tasks to support policy and actively for the central and provincial special funds for air pollution control.
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 horizontal 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.

Vacuum hot water boiler manufacturer tells you the trend of its development before the start of the first digression, say thirty blink of an eye we have to go to 80 after the thirties, we tend to consider the issues are becoming increasingly cost-effective, the same way use in a vacuum boiler body is the same, then our future horizontal vacuum hot water boiler should gradually toward which direction to meet the needs of consumers it? Xiao Bian gave you about the river south of the shares of fast production of vacuum boilers cost-effective reasons: 1, vacuum hot water boiler there is no swelling, explosion, risk of rupture, safe and reliable 2, a multi-purpose machine, can provide a boiler for heating water, domestic hot water, pool heating at the same time. 3, the design life of more than 20 years, can be placed in the basement and roof, the state authorities are not limiting. 4, efficient, low cost. 5, no scaling, corrosion and other phenomena. 6, than ordinary boiler small size. Modular and arranged in parallel, more efficient and reasonable operation of the boiler. You can only open when a willfully without having rated heat. 7, high degree of automation, building automation connection, unmanned management. Even if guarded, guards and without an operating license. Minimal training. 8, vacuum hot water boiler is slowly being accepted by all, mainly for civilian use, such as hotels, residential, office, bath centers, schools, shopping malls and other places. So the future of the vacuum boiler trend will gradually be applied to large and small areas, hotels, bathing, or a layer of building only need a small modular vacuum boiler can achieve the effect of four tons of coal-fired boilers, so What is still hesitant to inquire quickly it!
