industry fuel vacuum water tube boiler price

Learn vacuum hot water boiler vacuum hot water boiler is a safe and reliable boiler varieties, developed since 1975, gradually became popular worldwide. Also for his safe and reliable operation, long life, adaptability, and efficient energy-saving features, the annual market share has gradually increased. Vacuum hot water boiler furnace divided into two parts; the upper half portion of a vacuum chamber (vacuum vapor chamber), which is provided with a tubular interior space of the vapor - water heat exchanger for heating circulating water flowing through the heat exchanger . The operating principle: vacuum hot water boiler is running, the negative pressure in the vacuum furnace body heat medium water absorbs heat energy released by burning fuel, Boiling water circulating system encounters a stainless steel heat exchanger of the low temperature steam, low temperature steam rises, heating recycled water to users for heating or hot water. Itself is cooled steam condenses into water droplets fall to the surface again after the heating medium is heated, thereby completing the entire cycle. Heating medium water constantly in the body with a closed circulation heating evaporation == == == heat medium condensed water, condensed water without added thus, no danger of burning air. Vacuum hot water boiler using soda condensation heat, all heat exchangers operating condition, soda condensation heat transfer coefficient is the highest.

Nowadays, the heating of many residential areas is supplied by uniform boiler burning hot water, so the performance of hot water boiler plays an increasingly important role in consumer heating. The most common boilers on the market are vacuum hot water boiler and atmospheric pressure hot water boiler. However, many consumers do not have a thorough understanding of the two hot water boilers may have a certain deviation in understanding, the following is to understand the difference between vacuum hot water boiler and atmospheric pressure hot water boiler. One, the safety is different now professional hot water boiler is mainly vacuum hot water boiler, the inside of boiler is negative pressure energy At the same time, vacuum hot water boiler can be changed into normal pressure hot water boiler by correlation structure, so the safety is more obvious than that of vacuum hot water boiler. However, the normal-pressure hot-water boiler is safe and reliable as long as it is partially ventilated when it is used in the hot-water boiler, which is easy to use, so the normal-pressure hot-water boiler is especially safe and reliable. Second, the heating efficiency is different because the water volume of the vacuum hot water boiler is less, so the primary water quantity is less, so it is necessary to recycle and use burners for many times to heat the boiler. But the atmospheric pressure hot water boiler container only needs one time to open the burner can achieve the better heating effect, can effectively put the hot water boiler in the hot water boiler. When circulating water is heated, the thermal efficiency of atmospheric hot water boiler is higher than that of vacuum hot water boiler. Third, vacuum hot water boilers with different equipment complexity must be equipped with a series of basic facilities, such as vacuum pumps, in order to ensure vacuum degree, and atmospheric hot water boilers do not need to adopt control equipment to maintain vacuum degree. Therefore, it is easier to operate without complicated control equipment personnel, and the complexity of boiler equipment has the advantage of meeting the needs of more consumers when it is used. Nowadays, the hot water boilers with high sales volume are mainly vacuum hot water boilers and normal pressure hot water boilers. There are great differences in the use of these two points, both in Ann. The overall thermal efficiency or equipment complexity is different, so if you want to install the relevant boiler equipment, you can choose different machines and equipment according to your needs for hot water boilers.

Vacuum hot water 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.
