Household Gas Vacuum Fire Tube Boiler

The main features of the vacuum boiler (1) vacuum suction run, really not explode boiler, security is excellent. (2) steel boiler force the high temperature region, successful isolation of the high-pressure zone, so that the service life of the boiler prolonged 2-3 times, the design life of 30 years. (3) the overall design of scientific, rational, compact footprint saving 50-70%. (4) by heat exchange in a boiler body, overall efficiency of up to 91%, after starting the hot water may be provided within 70-80 deg.] C for 2-3 minutes, greatly reducing the warm-up period and reduce energy waste. (5) automatic control, can be implemented intelligence, or unmanned remote network control. (6) built-in stainless steel heat exchangers, water quality without any contamination. (7) Indirect cf. (boiler EHE + + + + the circulating pump installation costs) in the form of heat, the installation cost savings of more than 30-40%. High (8) efficiency, fast heating, good heat transfer, fuel cost savings of 20-30%.

Vacuum hot water boiler operating gas: a gas hot water boiler operating under vacuum: the vacuum gas hot water boiler utilizing the different characteristics of different boiling point of water at ambient pressure. At normal atmospheric pressure, the boiling point of water is 100 deg.] C, vacuum gas hot water boiler operating pressure in the range -0.07Mpa less. Corresponding boiling temperature of water is less than 93 deg.] C, vacuum gas at the operating pressure of the hot water boiler, the combustion temperature rises to the water boiling temperature, the steam boiling surface to produce the same temperature, volatile vapors absorb large amounts of heat. At this time, water is injected into the heat exchanger of the boiler. After the inner tube was heated to an outer cold administered heated steam flows out through the steam pipe outside the cold water cooled heat exchanger is condensed into water droplets, the water cycle is completed in vacuo. 1. smoke tube was added in the process, improve the heat transfer effect of making the arrangement more concentrated. With a square overall structure independent spray, beautiful shape of the separation. three. Large furnace techniques: effectively increasing the heat radiation area of ​​the unit, to reduce the nitrogen oxide emissions. 4. Boiler water using a high water to ensure that water does not furnace fouling and oxidation. All wet back shell type three-way structure, static heating, excess heat .6, actively control the whole system, it does not require special duty. 7. Unique pulse level detection circuit reliable performance. 8. inlet / outlet temperature display easier to control the operation of the vacuum and hot water boiler operating segment. 9, receiving advanced multilayer insulated glass wool, heat loss is small. Vacuum gas hot water boiler with three pressure safety system: automatic safety explosion-proof valve in the discharge control: when the internal pressure of the boiler continues to rise, the explosion-proof valve due to EHV broken, releasing the pressure in the boiler, to ensure safe operation of the boiler; Digital Pressure Switch: imported from Japan digital pressure switch, detecting a change in the pot at any degree of vacuum, when the pressure is too high, side off: opening vent automatic safety alarm: the boiler when the internal pressure becomes slightly positive pressure, vibration proof safety valve automatic alarm , cut off the power boiler.

The recent good news story: Union Square soon Group was named the provincial Federation of factory affairs leading group as "micro-small and medium private enterprises in Henan workers' congress building demonstration units" honorary title. Win the title, is inseparable from the efforts of all labor union workers, they work with their own solid foundation, effective operational mechanism and splendid achievements successfully nominated and award winning. Over the years, the Labor Union under the correct guidance of urban levels of trade unions, under the correct leadership of the Party, Comrade rely on the staff, smooth internal management channels, good to play the democratic management of conflicts "relief valve" business "stabilizer" and developing the "catalyst".

Gas-fired steam boilers of different types and their advantages on the common market gas steam boiler model, what does? According to data accumulated over the years, the statistics, the results are as follows, for your reference to understand. WNS fuel gas steam boiler, low cost, the implementation of the pipeline, so that lower gas prices, fuel cost decreases; the model of high boiler combustion efficiency, fuel savings, investment buying low fuel costs; the whole side pull butt welds, boilers the use of safe, long life, low maintenance costs. High efficiency, there is arranged a tail flue gas condensation recovery, can effectively control the exhaust gas temperature, high thermal efficiency of the boiler; using automatic burner, water continuous electric adjustment, high combustion efficiency. SZS fuel gas steam boiler, with international popular three-pass shell type, all wet back structure, large volume combustion chamber design, burning more fully. Internationally renowned burner, combustion chamber all-corrugated furnace structure, both to strengthen the flue gas disturbance, but also increases the radiation heat transfer area. Not only increases the stiffness of the furnace, and effectively weaken the expansion stress of the furnace; enhance both heat transfer, but also to promote the fuel combustion within the furnace. Vacuum gas hot water boiler, high safety, vacuum boiler because the phase change medium flow system below atmospheric pressure, absolute pressure inside the unit is running is 0.02 ~ 0.08MPa, the unit is in a vacuum state, and thus the explosion does not occur. Long life, internal boiler fouling does not occur, increasing the life of the boiler use. Heat exchanger portion with stainless steel, corrosion-resistant, the design service life of 20 years. High degree of automation, the use of the control device and mechatronic joint control programmable logic controller. Long life, scientific product design, advanced processing technology and strict quality control, all factory production of boiler equipment. The advantages of gas steam boiler in recent years reflects the more comprehensive. Exacerbate air pollution causes the gas steam boiler into the market faster. Gas-fired steam boiler is a clean energy, natural gas fired industrial boilers, and with the traditional burning of fossil fuels such as coal boiler has unparalleled advantages in comparison. Natural gas boiler steam boiler market development trend in the future, the future market development of industrial boilers except by factors affecting the pace of development of our national economy and the scale of investment, etc. In addition, more and more restricted energy policy and energy-saving, environmental protection requirements.
