Henan foam products hot water vacuum boiler which method is well known that oxygen oxygen corrosion is a key issue and safe operation of the boiler service life of impact, and with the development of the hot water boiler corrosion problems more prominent, so welcomed by the people of Henan in order to ensure the safe operation of the boiler, oxygen is imperative to take effective measures for the excellent quality of Henan boiler, the boiler Henan oxygen and what method? First, the thermal oxygen Henan boiler heat deaerator, which is the principle of the boiler water is heated to saturation temperature for the corresponding pressure of the oxygen on the water oxygen evolution revisit excluded, so as to ensure the oxygen content of boiler water reaches Henan water quality standards, and Henan boiler thermal oxygen addition methods may not only oxygen, but also to remove carbon dioxide and other gases, users need not worry about this method of oxygen will increase the amount of dissolved salt content and other gases. Second, the vacuum deaerator Henan boiler vacuum deaerator is at less than atmospheric pressure, which also belongs to the low temperature oxygen scavenging. The quality of Henan boiler vacuum oxygen effect, the key is the ability to ensure the vacuum. Will be the same time as the heat load fluctuations, airtight coupled with the entire heating system is difficult to ensure, thus oxygen in the vacuum heating system is not particularly widespread application, the user should pay attention to the selection of such a measure oxygen. Third, the oxygen resolved resolved by strong oxygen binding deoxygenated water and oxygen gas, to achieve the purpose of oxygen Henan boiler, which boiler oxygen Henan method may be performed at room temperature, heating it need not , saves energy, while parsing Henan boiler operating costs than the previous two kinds of oxygen is much lower, but not remove other gases, it also reduces the pH value. Further reliable method of oxygen Henan integrity not only more than several boiler, there is another hydrazine, sodium sulfite and the like oxygen chemicals, resins, and greater investment and oxygen oxygen steel scraps smaller investment, short when the user takes oxygen method for Henan boiler, good to weigh the pros and cons of various methods of oxygen, combined with the economic and budgetary requirements, select the most appropriate, most oxygen methods.

What are the characteristics of vacuum foam products hot water vacuum boilers?

Vacuum phase change boilers in the industry are usually referred to as vacuum boilers. Professional vacuum boilers form a negative pressure vacuum environment within the enclosed furnace body. There is no danger of expansion and explosion because a vacuum boiler creates a low-pressure environment with little air, and then uses water to boil at a low temperature to produce steam. As a result, it is now commonly used in higher elevations. Let's find out what the features of the vacuum boiler are.

1, the vacuum boiler will not corrode because the internal structure of the vacuum boiler is negative pressure vacuum state, so it is completely isolated from the atmospheric pressure, so the pump pumps configured by the various units of the boiler will continuously discharge the steam from the unit. It does not corrode the internal structure, so vacuum phase change boilers perform fairly well in terms of durability.

2, safety and reliability are different from ordinary atmospheric pressure boilers. Because vacuum boilers pump air out of the inner container to form a vacuum environment, the furnace body does not work under the vacuum body in the course of use and will not be expanded by heat. It is not a pressure vessel, so there is no risk of explosion. At the same time, if the pressure increases due to faults or other perceived factors, the vacuum pressure switch automatically cuts off the power supply, so vacuum boilers are more reliable than other types of boilers in terms of safety.

Vacuum hot water foam products hot water vacuum boiler on those points we need to know: we usually refer to the hot water boiler is divided according to different ways, have different classification; wherein if in accordance with the boiler pressure points, then, can be divided into atmospheric hot water boilers, pressure hot water boiler, vacuum hot water boiler; for atmospheric pressure and we may be more understanding, that comparison, for vacuum boiler maybe not so familiar with, then, as far as it relates to the problem, we have to carry out simple doubts, let us better understand its characteristics, uses, etc. 1. What is a vacuum? Divided into physical vacuum and vacuum industrial vacuum two kinds. Physical vapor space means no presence of particles, industrial vacuum pressure refers smaller than a standard atmospheric gas space, refers to the state of the lean gas, usually obtained with a special vacuum pumping machine, the vacuum in the vacuum are industrial boiler vacuum. 2. What is a vacuum hot water boiler? The so-called vacuum boiler, also known as vacuum phase transition boiler. When the normal operation means, the boiler pressure below atmospheric pressure inside the medium, the cold water is heated by the boiler phase change heat mode. 3. What are the key technology of vacuum boiler is? Key technology is the degree of vacuum vacuum boiler to maintain long-term stability, leakage rate is minimal. 4. What is the vacuum hot water boiler heat exchanger the material is? Heat exchanger disposed in the vacuum boiler SUS304 stainless steel tube. 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. The vacuum hot water boiler temperature control temperature control two ways:? Media outlet water temperature control and temperature control. The default for the water temperature control medium. When the water temperature is selected to control the combustion temperature is automatically adjusted with the water, but if the water medium temperature exceeds set limit on the medium water, burner heating was stopped, the water continues to be lower than the medium by the burner outlet temperature regulator when a temperature of 5 degrees limit status. 6. A vacuum boiler safety device which has a safety device for a vacuum boiler:? ① heat medium water temperature control, may control the temperature inside the furnace heat medium water; ② the heat medium water level control, may control the heat medium inside of the furnace body the level of water; ③ the beginning of the pressure, when the abnormal pressure rise within the furnace operation, the combustion is automatically stopped; ④ hot water temperature control, when the over-temperature water temperature, the combustion is automatically stopped; ⑤ destructive protection: explosion-proof valve. When abnormally high pressure furnace, steam furnace body is released to the atmosphere, to ensure that the unit never danger of explosion. 7. What are the main features ① vacuum boiler pressure vessel does not require local authorities to monitor, installation needed to use;? ② do not need to pay, no good water resistance, long life; ③ low energy efficient, operation and management costs; ④ reduce auxiliary, saving investment; ⑤ high safety performance. 8. Why ① vacuum boiler can be small energy radiative heat loss, the furnace is sealed vacuum vessel, itself has good thermal insulation properties; ② high heat exchange efficiency, the furnace body steam - water heat exchanger thermal efficiency is water - water? 10 times the thermal efficiency of the heat exchanger; ③ small thermal inertia: small boiler size, low water heat medium, the heat capacity is small, small thermal inertia and therefore, the reaction is sensitive to load variation. The boiler is turned on, i.e., 5 to 8 minutes with a hot water. ④ heating surface does not scale, energy saving. 9. Why vacuum hot water boiler blast furnace will never work in a vacuum, not a pressure vessel;? Body sealing of certain heat medium water, air will not burn in any state; the body with multiple self-protection device (anti-overheating, freezing, water shortage bit too high anti-pressure, shock, anti-gas fuel supply enough water, etc.). ? 10, vacuum boiler boiler host large investment it though the price is higher than ordinary vacuum hot water boiler, but it can save a lot by vacuum boiler auxiliary equipment investment: plate heat exchanger, a circulating pump, expansion tank soft water treatment equipment and so on, can also be save the corresponding pipeline installation fees, accommodation fees auxiliary power system control fees, investment is still lower than the average integrated hot water boiler system.
