Hospital Gas Vacuum Fire Tube Boiler Dealer

High and sometimes low when the boiler manufacturers to teach you how to deal with gas boiler and tempering from the fire boiler manufacturers now teach you how to deal with gas boiler and fire off phenomenon of tempering gas boiler backfire and from the fire, there will be vacuum furnace , rather unstable; observe the test flue gas CO2 and O2 instruction sheet change significantly; the color of the flame is also changing moment. Gas steam boiler manufacturer to tempering occurs and causes a gas boiler fire off phenomenon, summarized as follows: the gaseous fuel in a gas boiler combustion within the limits, if the ratio of the flow rate of the combustible gas concentration than the burner air low burning speed, the flame will spread towards the fuel source direction, the emergence of the so-called backfire. According to gas steam boiler manufacturers found that the higher the gas-fired boiler furnace, the faster will be the speed of flame propagation, flashback will be easier. Since tempering phenomenon occurs in the burner, so that damage to the burner is relatively large, serious, explosions occurred in the burner. Tempering phenomenon and compared, with the proviso that fire off phenomenon occurs: the combustible gas in the burner outlet is higher than the flow rate during combustion, resulting in the original direction of the fuel toward the burner starts combustion, a phenomenon known as off-firing. The study found that, when the gas boiler is under low load conditions, the boiler is more prone to fire off phenomenon. Tempering treatment from the fire and gas boiler: 1, by detecting if it is due to the low gas pressure caused, which requires gas pipeline gas boiler thorough examination. If it is caused by the gas pressure is too high, you need to run normally throughout the regulating valve on the gas pipeline, high and low pressure air duct before the total pressure and burner, throttle opening size of the burner to do a rigorous inspection. 2. If it is the total gas boiler room gas supply pipeline pressure drop caused by the need for timely contact with the gas supply station, rapid increase in gas pressure to solve. By checking if the intake pressure is normal, it is necessary to detect the pressure regulating valve is normal. After checking the above aspects, if no problem, we need to leak gas pipeline to be checked.

At the same time, the vacuum hot water boiler also has many advantages, fast boiler as well-known vacuum hot water boiler manufacturers, research and development of production capacity has been an industry leader.

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.

School education is the foundation for development of our country, to provide environmental and healthy living environment for students is our top priority school. Winter is fast approaching, fast boiler heating and for us to solve the problem of the coexistence of environmental protection, give us tremendous help provide heating in winter. --customer feedback
