Vertical gas fired vacuum hot water boiler for hotel

Commissioning of Electric Steam Boiler before it is put into OperationThere is still a series of commissioning work to be done before the steam boiler is put into operation. The two key steps are fire-raising and gas supply. It is necessary to control the temperature strictly and not to increase the ground too fast in order to avoid the non-uniform heating of every component and affect the service life of the boiler after the boiler has no loopholes in the equipment. The temperature of the boiler should be strictly controlled during the process of fire-raising and the temperature should not be increased too fast. In recent years, with the development of science and technology, sterilization equipment has been constantly updated, pulsatile vacuum pressure cooker has replaced the lower exhaust pressure cooker. And at the beginning of the gas supply, the heating operation should first be carried out, that is to say, the steam valve should be slightly opened to allow a small amount of steam to enter, thus giving rise to the effect of preheating the heating pipe. At the same time, pay attention to the normal operation of the components. After these steps, the steam boiler can be used normally. An electric steam boiler replaces an old-fashioned boiler where coal burns to produce steam. The new equipment has many advantages, but the performance has also changed. In order to ensure the safe use of the equipment and prolong the service life, after several years of research, some experiences have been accumulated in the correct installation and commissioning of the equipment. When the steam boiler leaves the factory, the staff shall carefully check whether the physical items are in full conformity with the list details, and must ensure the integrity of the equipment. Upon arrival in the installation environment, equipment and spare parts need to be placed on a flat and spacious ground Top to avoid damage to bracket, seat, etc. There is also a very important point is that after fixing the steam boiler, carefully check the boiler and the base contact place whether there is a gap, to ensure that the tight seam, there are gaps should be filled with cement and so on. At the time of installation, the most important component is the electrical control cabinet, need to connect all the wires in the control cabinet to each motor, then install it.

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.

Food plant causes corrosion and the effects after stopping the boiler factors: food factory after disabling boiler corrosion causes and influencing factors after food factory boiler shutdown, with decreasing pressure and temperature inside the boiler steam condenses into water, boiler a vacuum inside, the outside air leaks into the furnace, the oxygen and water vapor in the vapor state. Metal is prone to corrosion. Boiler structure, if you do not take some measures to stop the use of corrosion is inevitable. For example, can not be discharged superheater superheater water. When the internal heating surface has a water-soluble metal salt scale, when it absorbs water, will form a high concentration solution of salt, which will aggravate the etching stopper, internal corrosion is formed ulceration. Often this is the entrance to the superheater. Because the separated saturated steam upon entering the superheater boiler always carry a small amount of water, the saturated vapor absorption heat upon entering the superheater, the boiler water is evaporated into steam, boiler water salt deposited on the inner wall of the superheater. Heater inlet pipe.

In recent years, the state environmental protection is all the more attention we as a company with the times, in order to respond positively to the implementation of the national environmental protection requirements from coal to gas project. But the choice of boiler suppliers in this area quite a headache, after repeated comparison and investigation, we chose to partner with fast boiler. Fang did not disappoint quickly proved that the recommended boiler operation after use to fully meet our needs, both energy saving and environmental protection, high thermal efficiency, to a certain extent, cost savings for our fuel. --customer feedback
