The formation of vacuum gas hot water vacuum boiler dealer provisions vacuum gas boiler set up the day there are many issues deserve attention, in the formation should have rigorous, failing that there are many hidden dangers behind, what had to be concerned about when it set up a public, make sure the gas vacuum the formation location of the boiler, if it is established businesses should have to inform the relevant departments have a license before they can install. Second, do the registration dossier, China clearly requires a vacuum gas boiler should have to register and do business related files, and second, the need for certified staff as established. Third, the study initiated by the operator often set up with the standard of credible standards and clear view of the formation of knowledge about the arrangement. Fourth, vacuum gas boiler before the formation of the first vacuum gas boiler host, with each component ignition advance detection equipment, should have to complete the notes, if there are problems, you should have instant changes made to the plant equipment. It is certainly relevant provisions of the above-mentioned gas boiler formation of a vacuum, a certain amount to the public in the early days of preparation, good planning in advance, to avoid problems such as the level of problem or placement will directly affect the progress of the formation of the back of the output.

Good hot water hot water vacuum boiler dealer which brand? Henan fast boiler hot water boiler Description; a new environmentally friendly combustion, i.e. fully premixed fuel and air, by precise adjustment and control to ensure complete mixing of gas and air, the combustion more fully, using a surface combustion technology to improve combustion efficiency and reduce NOx emissions. NOx emissions less than 18mg / Nm3. It has simple structure, convenient operation, the user simply to operate the boiler control cabinet automatically switch opening operation. Premix combustion ratio can be achieved adjusted range up to 20 to 100%. UItraten Technology - wings tube new ultra-tube heat exchanger powder - quill, energy efficient, highly advanced technology is condensed, to ensure the efficient use of energy and fully absorb the latent heat of evaporation flue gas produced after combustion, fully absorbed the vaporization latent heat of combustion flue gas generated. Thus, energy can be effectively utilized, energy conservation and improve efficiency. Use of high thermal conductivity aluminum-silicon alloy greatly extend the life of the compression element. Boiler boiler protection system has high pressure, ultra-low protection. When the supply voltage exceeds the normal range, automatically cut off the boiler supply and alarm. The boiler has a temperature sensor fault protection, each boot, boiler control system first detects (http://www.chemdrug.com/sell/76/) sensor condition, such as abnormal boiler is automatically cut off power and alarm. Boiler water alarm has the features: the boiler when the boiler water level is below the safety level, the boiler power is automatically cut off the alarm. Triple temperature protection system; over-temperature heat medium such as water protection system: Built boiler PT100 temperature sensor time monitoring the temperature of the water medium, the medium is stopped when the water temperature exceeds the set temperature of the combustor; Protection exchanger water temperature: by detecting the heat exchanger outlet temperature, controlling start and stop of the burner to protect the safety operation of the boiler, reducing fuel consumption; secondary overheat protection: overheat protection when the system is not working, the second over protection system operating in time and cut off the power boiler; a digital pressure switch: the original Japanese inlet digital pressure switch, change of the degree of vacuum in the boiler can be readily detected; when the pressure is too high, the combustion is stopped; explosion-proof valve automatic security alarm: the boiler when the internal pressure becomes slightly positive pressure explosion-proof safety valve alarm starts automatically cut off power boilers; emission automatic safety explosion-proof valve: when the boiler pressure is increasing, because EHV explosion-proof valve is broken, releasing the pressure in the boiler, to ensure safe operation of the boiler; flow switch protection; automatically detect traffic tail heating surface, ensure that sufficient cooling tail heating surface; frost protection system; burner flame failure Alarm; burner motor overload, fault protection. Key Technology vacuum leak condensing boiler embodiment is that long-term stability the degree of vacuum, the leak rate is small. Some data suggest that, if the boiler contains non-condensable gases such as air, even if the gas is weak, will have a very detrimental effect on the condensation heat transfer process. For example, air containing 1% by mass of the steam heat transfer coefficient can be reduced by 60%, resulting in serious consequences. Therefore, improving the sustainability of such a degree of vacuum of the boiler through a variety of ways is an important element. Henan fast boiler series vacuum condensing boiler is detected by a helium leak detectors, to ensure the long-term maintenance of the vacuum boiler! Vacuum automatic maintaining means introduced into the vacuum boiler operation, the interior portion of the vacuum boiler, but because of the following reasons, non-condensable gas in the boiler as the boiler operation is gradually increased. First: furnace leakage: weld seal, a slight leakage of steel. Second, no condensable gas (not prevent): water and heat medium furnace (steel plate) to release the non-condensable gases (H2 of), directly affects the degree of vacuum in the boiler. However, a chemical reaction while forming a protective film (ferric hydroxide) in the steel sheet surface, as a barrier to chemical reaction. Based on experience, the chemical reaction stops after the boiler operation two years. When the vacuum boiler non-condensable gases, the pressure will be increased, i.e., the degree of vacuum damage. Effect of non-condensable gases to the vacuum boiler heat transfer efficiency is very serious. When the non-condensable gas volume fraction of 0.2%, 20% thermal efficiency, the water temperature can not be increased, reducing the boiler output. Therefore, the non-condensable gas must be drawn vacuum boiler running.

The comparison of hot water vacuum boiler dealer 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.
