China gas fired vacuum boiler

Vacuum gas china fired vacuum boiler what type of boiler equipment? Vacuum gas boiler is very popular in recent years, a new type of boiler, and Henan as a domestic first began manufacturing and sale of vacuum hot water boiler and the given area, vacuum gas hot water boiler manufacturers is more, especially in Zhengzhou, all kinds of boiler plants are not there are nearly one hundred dozens technology for manufacturers, vacuum gas hot water boiler is very simple, because these are common, in addition to some of the core components, other principles are similar, then how do we distinguish so much Which is good in the factory in the end? This chapter will give buy gas hot water boiler under vacuum explain all skills. Zhengzhou Gas vacuum hot water boiler plant based on qualifications, experience, technology, patent number can be divided into two kinds of brand manufacturers and sales of manufacturers, most of the manufacturers are small manufacturers sales, meaning only the sales of qualified no manufacturing qualification, but also they can not do when it came to the boiler, they will go to the brand boiler manufacturers and other customers to order and then pay later make the difference, so these small boiler plant is not have the technical conditions, not to mention the after-sales service and the attitude! So to remind our customers that the purchase be sure to look for the brand in the purchase, at least allow customers at ease in the latter part of the sale, then the situation would not admit to buy does not occur.

Third, vacuum hot water china fired vacuum boiler to take automatic intelligent control mode, can be realized when using the remote or unmanned intelligent network control can be used to manipulate the device, and the inner stainless steel boiler provided with a heat exchanger so as not to appear rusty phenomenon and not pollute the water.

Vacuum hot water china fired 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.

It is understood that, recently, the ecological environment Department of Henan Province issued the "Henan electricity in 2019 non-standard governance program industry" and six special programs, mainly to further promote the campaign of air pollution control, to ensure that the province's ambient air quality continues to improve. Meanwhile, the "plan" also made clear this year Henan Province industrial air pollution control in key tasks.

The province meet the conditions of steel, coke, cement, carbon (including graphite), flat glass (including electronic glass), aluminum and other six major industries and enterprises, the requirements before the end of this year to complete the mentioned standard treatment, the required limits for reducing pollutant emissions. Carry closed down or banned brick kiln, lime kiln, tunnel kiln, firing kiln and a variety of smelting furnace, roaster and so on nine categories of Kiln, upgrading, restructuring and integration work. Before the end of October this year, all kinds of industrial furnaces to achieve discharge standards.

Before the end of June this year, the province's petrochemical, oil refining, industrial coating, packaging, printing, chemicals, pharmaceuticals and other industrial enterprises, the full completion of volatile organic compounds pollution control; before the end of August, the province's petrochemical, oil refining companies to complete volatile organic compounds depth governance and leak detection and repair of governance; before the end of December, the provincial cities of built-up areas phasing out the open dry-cleaning machine.

Before the end of October this year, in addition to undertaking tasks and will not have the alternative livelihood conditions, the province completed 35 steam tons / h coal-fired boilers and the removal or clean energy transformation, provincial cities and county (city) district built 4 tons of steam and above gas-fired boiler, fuel (including alcohol-based fuel) boiler low nitrogen transformation complete, the provincial municipality to build a biomass boiler area (including biomass power plants) completed the first ultra-low emissions transformation. Before the end of June this year, the completion of the provincial cities to build coal-fired facilities Chaigai all industrial areas.
