Bathroom Gas Vacuum Water Tube Boiler Dealer

For increasingly strict emission limits of air pollution, low nitrogen introduced condensing gas hot water boiler, premix gas hot water boiler fully condensed, ultra-low emissions coupled vacuum boiler, nitrogen oxides (referred to as NOx) may be as low as 18 mg / cubic meter.

This is our first collaboration with fast boiler, professional and caring service fast boiler's impressed us. From pre-sales advice to after-sales guidance, every step is very careful and thoughtful. They provide hot water boiler performance is also very good, and effectively improve the level of our heating units. --customer feedback

Good hot water boiler 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.

Because some oxygen corrosion accumulation of dissolved oxygen in water will result in the boiler feedwater process intensifies, therefore, at the same time equipped with the appropriate oxygen equipment should be better control of the intensity of the entire water supply. The oxygen present embodiment mainly sodium sulfite chemical reaction oxygen, this effective method of oxygen can fully reduce the overall corrosion to metal. Meanwhile, some capacity is relatively increased water boiler, may also be employed in high vacuum or low oxygen equipment, a reasonable way is to use hot water boiler air evacuated, forming a gas hot water boiler pressure less than atmospheric pressure will reduce air leakage phenomenon occurs, play a good maintenance effect.
