wood based panel industry natural gas vacuum fire tube boiler price

Leshan fuel gas vacuum vertical and horizontal hot water boiler choice for us in the process of vacuum hot water boiler selected, will be exposed to technical doubts. Well, small series with public elaborate. Cost vacuum boiler hot water boiler is mainly composed of the unit cost of a vacuum, burner costs associated accessories (circulation pumps, instrumentation, valve full) the cost thereof. Decided to vacuum hot water boiler cost reasons, there are more important effect of the place: the production of brand differentiation, manufacturers, manufacturing techniques, testing, industrial design, selection of iron and steel and so on. Its interior, the most should pay attention to the following reasons: Ⅰ- productivity producers productive producers of vacuum hot water boiler, largely determine the good and bad of the product. Due, a productive enterprise, remove components on the market more exclusive, we have extensive experience skills. Secondly, and of course, the level of commitment to product design. The size of the level of industrial design standards, a direct impact on the quality of the products is quite large. Affect the future security of the application products, energy conservation sex, sexual fly, and the degree of convenience. The quality of steel selected parameter B- steel, is the cornerstone of their products. Excellent specification standard steel, is to ensure the vacuum seal of the hot water boiler stable utility. Many small factories with non-standard applications or substandard steel, will cause a vacuum hot water boiler products, poor security, high energy costs, and risks exist fly, say users, although that was enough time cost savings, but Suizhudanque. ⑶- automatic production level of manufacturing process vacuum hot water boiler, fuse, coil, fuse, should be the most important skill. These three techniques, the comparison must be to, human operator, using automated manufacturing, the highlight is very obvious. Due to automated manufacturing, with higher reliability, smaller mistakes. This is also a big production of brand vacuum hot water boiler products, far better than an important reason for small-scale production of the brand. Due to its manufacturing and finally, the level closer to the level of industrial design, to achieve a good standard specification set. Some guidelines D- inspection domestic production plants, will not have a lot of time after strict vacuum hot water boiler products, factory link test. Stress test ended, even if the product is excellent. This behavior is certainly not quite fulfill its responsibilities seriously. Excellent test criteria must primarily bear: Stress test test test inert gas, seam welding inspection, the degree of sealing of the test, the relevant section of the trial period. Can be neglected, it can be neglected. Only so, to ensure that users have a good grasp of the product, allowing users to use the process in the future, reduce non-compliant products have caused, directly affect the user's daily production activities. e- repair maintenance of the quality of most of the small factory, there will be no maintenance repair and maintenance. Sale and the entire staff entrusted agent responsible. But most of the agency staff, basically no commitment level team. After the cause of non-compliance will result in delayed, or with consequences often can not handle. In summary, summed up as, because of the cost of vacuum hot water boiler, the direct impact. Generally speaking, good, excellent vacuum product cost hot water boilers, hot water boiler vacuum the unit plus burner, almost, 700KW, 10 million decision.

The principle of a vacuum hot water boiler, 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.

Commissioning of Electric Steam Boiler before it is put into OperationThere is still a series of commissioning work to be done before the steam boiler is put into operation. The two key steps are fire-raising and gas supply. It is necessary to control the temperature strictly and not to increase the ground too fast in order to avoid the non-uniform heating of every component and affect the service life of the boiler after the boiler has no loopholes in the equipment. The temperature of the boiler should be strictly controlled during the process of fire-raising and the temperature should not be increased too fast. In recent years, with the development of science and technology, sterilization equipment has been constantly updated, pulsatile vacuum pressure cooker has replaced the lower exhaust pressure cooker. And at the beginning of the gas supply, the heating operation should first be carried out, that is to say, the steam valve should be slightly opened to allow a small amount of steam to enter, thus giving rise to the effect of preheating the heating pipe. At the same time, pay attention to the normal operation of the components. After these steps, the steam boiler can be used normally. An electric steam boiler replaces an old-fashioned boiler where coal burns to produce steam. The new equipment has many advantages, but the performance has also changed. In order to ensure the safe use of the equipment and prolong the service life, after several years of research, some experiences have been accumulated in the correct installation and commissioning of the equipment. When the steam boiler leaves the factory, the staff shall carefully check whether the physical items are in full conformity with the list details, and must ensure the integrity of the equipment. Upon arrival in the installation environment, equipment and spare parts need to be placed on a flat and spacious ground Top to avoid damage to bracket, seat, etc. There is also a very important point is that after fixing the steam boiler, carefully check the boiler and the base contact place whether there is a gap, to ensure that the tight seam, there are gaps should be filled with cement and so on. At the time of installation, the most important component is the electrical control cabinet, need to connect all the wires in the control cabinet to each motor, then install it.
