Compare the amount and pressure-type coal-fired hot water boiler vacuum boiler: a boiler, hot water boiler of this kind, their learning, will be continued, so, so that we can know and understand how some of the and at the same time, also can further increase their expertise in this area, and thus, to increase their amount of knowledge in this area, so it will not be nothing, thus, wasted such a good learning opportunity. , Then the hot water boiler 1. What are the advantages of factory set sealed vacuum hot water boilers and boiler, the boiler compare these two words? The hot water boiler vacuum boiler compared needle, then, the advantages of hot water boiler, a pressure type for water temperature is 95 degrees, but the vacuum boiler is not, it can only reach the upper limit of 80 degrees. In addition, hot water boiler in the production process, unlike the less stringent vacuum boiler, its quality is not difficult to compliance. 2. pressure hot water boiler type, if its coal-fired hot water boiler, so that the amount of coal, mainly related to what? Pressure hot water boiler type, if it is the type of coal, so that the amount of coal, mainly coal and thermal efficiency and heat boiler related, and that is a great relationship. As for how to calculate, there is a corresponding calculation formula, it is possible to control the formula, in order to obtain accurate results. 3. The pressure hot water boiler, the boiler water level at gauge that shows whether or not zero? As well as its product model, there are several parts? Pressure hot water boiler this kind of hot water boilers, water level gauge line, which is a display of zero, because the boilers is apertured to communicate with the atmosphere,

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, factory set sealed vacuum hot water boilers; 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.

To further reduce emissions of air pollutants and improve air quality of the environment, the Shanghai Municipal People's Government Office issued the "Opinions on accelerating the transformation of the city mentioned standard boilers of small and medium" (hereinafter "Opinion"), to accelerate the introduction of Shanghai City small boilers mentioned standard transformation respond positively.

Before the end of 2018, the district in conjunction with boilers and industrial distribution block, complete the development and revision of the Gas Pipeline Network Planning in this area. City, district authorities, according to the unit Gas Pipeline Network Planning and excavation plan, speed up the construction of natural gas pipeline network.

Variety of boiler fuel to replace natural gas, natural gas pipeline network (municipal pipe network to users outside the red line pipe) 50% of the cost of laying borne by the gas company; the remaining 50% by the district government and users each pay half, and encourage qualified district to provide more support. On the outskirts of the gas pipeline construction is temporarily unable to reach enterprises in the region, while ensuring security compliance cases, it can be in the form of non-natural gas pipeline, and implement an orderly transition after the completion of the pipe network. Encourage alternative gas supply business enterprises to provide gas price discount for the gas boiler.

10KV for the implementation of alternative electric boiler, 35KV and other business expansion project, to which the power supply capacity of the electrical part of the boiler, according to the city's non-resident business expansion project quota standards, engineering fees charged by half.

Environment departments to strengthen law enforcement and inspection of boiler units, fuel use, operation and maintenance, equipment maintenance, inspection, non-functioning facility once found, according to the law severely punished; at the same time, strengthen supervision and monitoring, if it is found excessive emissions, according to law strict punishment.

Boiler units and boiler mentioned standard transformation service units bear the main responsibility for the boiler safety issues involved. Site construction unit must have the appropriate boiler manufacture or installation (reconstruction) qualification, boiler commissioning personnel must have the appropriate special equipment operator certificate. Prior to the construction site mentioned standard boiler units to implement the transformation, boiler location should be informed in writing of special equipment regulatory authorities.

The district government is the responsibility of the main boiler to mention the transformation of the standard, according to the "ground principles" to promote the transformation of the boiler. Combined with the actual circumstances of the district reform implementation plan, accelerating the construction of facilities to ensure timely completion of the task of transformation, to ensure that policies and financial support in place.

(1) the internal environment of electrically heated vacuum phase change boiler is vacuum state when it is operated by electric heating vacuum phase change boiler. In this case, the oxygen in the intermediate water will be discharged to the outside of the electro-thermal vacuum phase change boiler, so the oxidation corrosion will not be caused in the boiler and the equipment will be damaged. At the same time, the heat exchanger part of electro-thermal factory set sealed vacuum hot water boilers is made of stainless steel and will not be corroded. In addition, the electro-thermal vacuum hot water boiler only needs to add a small amount of heat medium water at one time, it will not increase or decrease during operation, so there will not be scaling in the interior.
