What are the advantages of vacuum hot water industry vacuum boiler for sale in the heating aspect?

Winter heating has been one of the most important projects in northern China, some of the longer residence time residential district heating boilers generally use pressure or pressure hot water boiler, but most of these boiler systems there are complex, high operating costs, easy scaling, seriously affect the oxidation corrosion and other defects, residential areas, it will bring a lot of adverse effects. In recent years, it is widely favored by vacuum hot water boiler heating industry, and due to its excellent safety performance and minimal footprint and other advantages, is very suitable for building a heat source.

Vacuum hot water industry vacuum boiler for sale 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.

The comparison of industry vacuum boiler for sale failure rate: 1, vacuum degree of vacuum boiler in vacuum boiler * important index of stable operation of furnace, and four main factors that often affect vacuum degree: 1) whether there is leakage point in boiler body and valve, instrument, and so on. At present, including imported valves and meters can not ensure that there is no leakage within 3 years. 2) it is inevitable that failure of control part, boiler controller and negative pressure, pressure controller will also happen in operation, for example, the failure rate of domestic controller is even higher. 3) vacuum pump, three-way solenoid valve is working normally or not. As a result of the vacuum pump, the three-way solenoid valve is not operating very often and is originally installed Mouth also easy to appear the card dead and in the operation occurs the fault. 4) the load can not change abruptly, the boiler load change is very normal for the boiler, generally, the boiler can meet the load regulation of 30% ~ 100%. The above faults will cause the change of the vacuum degree of the boiler. At this time, the gas tightness of the boiler, whether the control part is normal or not, the vacuum pump, the three-way solenoid valve are normal or not, and the change of load should be checked. If all normal should be checked negative pressure and pressure controller settings, all normal vacuum recovery boiler can still be normal, otherwise the boiler should be shut down and overhauled all-round inspection. The failure maintenance rate of vacuum boiler in actual operation is higher than that of existing boiler. Pressure steam boiler, control requirements are higher than steam boiler. 2. The normal pressure boiler only has the basic time, temperature, water level control, hot water boiler controller selected the original inlet, the failure rate is relatively low. There is no need to maintain vacuum control equipment, without complex control equipment, personnel operation requirements are simpler than vacuum boilers, the probability of downtime maintenance is less, the actual operation of hot water boiler is much more stable. The comparison of boiler safety: 1. If the vacuum degree of the vacuum boiler is not guaranteed due to the above four factors, it may cause the boiler pressure to rise rapidly, and the boiler body is a closed structure, and the operator may cause the boiler pressure to rise rapidly. If paralyzed, it is possible to become the danger of pressured steam boiler, the vacuum operation of vacuum boiler is more safe based on the premise that the vacuum degree of boiler can not appear problem. 2. The atmospheric hot water boiler of atmospheric pressure boiler is as simple as boiling water, and no fault will cause boiler pressure. The boiler www.boilermanufactory.com is more safe and reliable, and it is really free of any danger.
