Factors affecting boiler efficiency indicators vacuum which specific? Of coal are carrying vivid motion to natural gas, the use of a vacuum boiler, greatly reduces the fouling of infection, while discharging nitrogen oxides and other hazardous gases obtained press. Power navigation key goal is to measure vacuum boiler, behind a discussion of a number of incentives under the influence of vacuum boiler power goals. Well, the following fast boiler company Xiaobian for everyone to share, with a look:

Compare the amount and pressure-type coal-fired hot water boiler vacuum boiler: a boiler, hot water boiler of this kind, their learning, will be continued, so, so that we can know and understand how some of the and at the same time, also can further increase their expertise in this area, and thus, to increase their amount of knowledge in this area, so it will not be nothing, thus, wasted such a good learning opportunity. , Then the hot water boiler 1. What are the advantages of vacuum hot water boiler and boiler, the boiler compare these two words? The hot water boiler vacuum boiler compared needle, then, the advantages of hot water boiler, a pressure type for water temperature is 95 degrees, but the vacuum boiler is not, it can only reach the upper limit of 80 degrees. In addition, hot water boiler in the production process, unlike the less stringent vacuum boiler, its quality is not difficult to compliance. 2. pressure hot water boiler type, if its coal-fired hot water boiler, so that the amount of coal, mainly related to what? Pressure hot water boiler type, if it is the type of coal, so that the amount of coal, mainly coal and thermal efficiency and heat boiler related, and that is a great relationship. As for how to calculate, there is a corresponding calculation formula, it is possible to control the formula, in order to obtain accurate results. 3. The pressure hot water boiler, the boiler water level at gauge that shows whether or not zero? As well as its product model, there are several parts? Pressure hot water boiler this kind of hot water boilers, water level gauge line, which is a display of zero, because the boilers is apertured to communicate with the atmosphere,

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 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.
