commercial 5000 kw vacuum hot water boiler for sale

The principle of a commercial 5000 kw vacuum hot water boiler for sale, 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.

Steam electric boiler maintenance and fast boiler pump classification Henan Xiao Bian told you about the company's steam boiler maintenance and electrical vacuum pump steam boiler maintenance classification should pay attention to 1, boiler maintenance, must be cut off and must relief. 2, the burner every two months to be removed from the boiler, carefully remove foreign bodies such as dust and soot. Photocell light-receiving surface wipe once a month, fuel filter should always be kept clean and filtering capabilities; carefully clean the filter in the pump, do not break the seal. Oil-burner not idle, so as not to damage the pump. 3, the water level gauge should always be kept clean, rinse the purge valve is opened, the water level in order to ensure a clear day. 4, pulling the safety valve once a day, to prevent rusting failure. 5, the boiler stops longer running time, cut off the power, and do maintenance work: (1), dry maintenance, shutdown after the release came out water, dirt clean the furnace, slow fire the pot with a burner after drying (burn time not too long, to avoid damage to the boiler), then drain all of the gas boiler, all pipe valve closed, checked every three months. (2), wet maintenance for a period not exceeding one month shutdown of the boiler, furnace shutdown after water release, discharge and clean fill with water, cut off the power, close the valve. The vacuum pump is divided according to use: a roughing pump starts to decrease from atmospheric pressure to a vacuum pump system to work the other pumping systems. 2. High vacuum pump operating in a high vacuum range. 3. The main pump in the vacuum system, the vacuum pump used to obtain the desired degree of vacuum. 4. foreline pump foreline pressure is maintained for a further vacuum pump in which a pressure below the critical backing. 5. coarse / low pressure pump starts from the atmosphere and for obtaining a low degree of vacuum of the vacuum pump. 6. The booster vacuum pump is mounted between the low and high vacuum systems to improve the efficiency or reduce the vacuum foreline pump capacity requirements. 7. The ultra-high vacuum pump works in the ultra high vacuum range. 8. A pump is maintained in a vacuum system, when the gas amount is small, can not be effectively utilized master, before the pump, In this case, with a smaller capacity auxiliary backing pump to maintain the main pump containers or maintain a desired degree of vacuum . Henan is committed to fast boiler steam boiler manufacturing, product quality, reasonable prices and widespread industry praise, if you have any needs, please contact us!

Jiangmen City, Guangdong Province issued 2019-- 2020, winning the Battle of Blue Sky embodiment, as follows.

1, a ban on new or expanded coal-fired thermal power units of fuel oil or coal-fired captive power plant business. A ban on new 35 tons of steam per hour of coal-fired boilers. Not the implementation of clean energy transformation and more than 35 tons of steam coal-fired boilers to complete the transformation of ultra-low emissions or shut down independent choice by the end of 2020.

Select vacuum boiler three major reasons vacuum boiler is a hot water boiler, which is mainly used to provide heat for the masses. Like hotels, living cell, and so in some places, need to use a vacuum boiler, vacuum boilers indeed be said to be an expert in people's lives. However, although many people buy a variety of vacuum boiler, but there are a few friends do not know why the use of a wide range of vacuum boilers, now Xiaobian bring everyone to look at the reasons for choosing the vacuum boiler. One. Runtime secure good quality of the vacuum boiler during operation, the pressure within it is artificially set within a range, so that the gas in the interior of a vacuum state, even if the internal pressure is due to a fault cause is not greater than the external pressure , the vacuum boiler can be automatically cut power, to prevent water overflow. This design not only ensures the safety of electrical appliances, but also so as to avoid unnecessary losses and a series of troubles caused by lack of water. two. Energy efficient operation of the boiler performance and stable vacuum in the vacuum state, effectively improve the thermal efficiency of the conversion. Application of vacuum boiler body is wet back three-pass design, a large amount of area to improve the radiation and convection heat transfer area, such that the energy intensity of the vacuum boiler once again increased. Vacuum boilers not only to reduce the pressure on his own life, but also to achieve the environmental protection concept proposed by the national government, it would be to make a contribution to environmental protection. three. Easy to transport vacuum boiler modular design, not only high-performance heat exchanger, and a small volume units, more easily during transportation, and because of its small size, even in a small area of ​​the space where it is possible to multiple units connected in parallel use. When long-distance transport needs, vacuum boilers occupy a lot of advantages. Good quality vacuum in the boiler during operation than traditional boiler more safe and reliable, and it is built of stainless steel heat exchanger, without any pollution on the water quality, but also a longer life than conventional boilers and enables efficient energy saving, due to the use easier when modular design makes transport. These are the three major reasons for selecting vacuum boiler, vacuum boilers popularity and good reputation in the market are generally higher, the reason why it is loved by consumers because it sells these vacuum boiler can have more than these advantages, these advantages have vacuum boiler is really reassuring products.
