Why vacuum ship vacuum tube boiler dealer may be exempted from inspection for the purchase of the boiler manufacturers, all these can be considered for production of vacuum boilers, boiler because it does not require supervisory inspection. Why vacuum hot water boiler does not need to check? This begins from the principle of vacuum hot water boiler. The so-called vacuum space generally refers to the state of the substance does not exist. It refers to the so-called industrial vacuum atmosphere, a pressure less than normal atmospheric pressure, known as industrial vacuum. Vacuum in the vacuum boiler belonging to the category of industrial vacuum, i.e. a vacuum in the boiler operation, the internal pressure of the furnace is less than atmospheric pressure in a closed environment. Boiler explosion due to the expansion caused by the medium in the space, which is higher than atmospheric pressure outside the pressure range of the furnace. Like blowing balloons, if too many balloons in the air strike, under the pressure of the balloon, the balloon will explode. The vacuum suction operation of the boiler, the internal pressure less than atmospheric pressure, while maintaining the vacuum furnace, it is impossible explosion. So, from the point of view of boiler manufacturing principles, vacuum boiler is a relatively very safe boiler. Vacuum boiler can be installed on the roof of the building, the basement boiler room and independent, user-friendly planning and construction of heating systems, saving investment. Vacuum hot water boiler, the state also issued a related legal documents specified vacuum boiler can register for free, free inspection.

How to choose cost-effective vacuum hot water ship vacuum tube boiler dealer brand Normally, when we choose a vacuum hot water boiler, we will have to worry about this or that. We do not know our choice of product quality and operating results. The following small series will take you to do a simple understanding. Raw materials (1) boilers used in production, process, technical rigor and professionalism of the operation is the first question we have to consider. This requires before making a decision, we can plant site testing to understand the operation of the process and the entire extent of the standard boiler production, and trade-offs. (2) using the selected boiler reputation in the market survey, a good boiler brand should stand the test of time and space, put into use if the actual boiler performance indicators in line with user requirements, and security and stability operations, then select it reliability will be higher. (3) vacuum hot water boiler brand is worth taking, as well as other criteria, namely its technology R & D results, namely its research and development efforts in all aspects of the thermal efficiency of the boiler, the boiler emissions. Because one of these are also put to use in the boiler should be noted that the core issue. (4) The last thing to consider is its service and after-sales service. If we can make brand standard recognized by customers, we must have a strong after-sales service and support to ensure our boiler products can be assured that easily buy. In short, the boiler brand merits, the evaluation criteria are diverse, boiler in order to select a good brand, we need to consider these questions.

Daly implementation of the "cut cut coal oil" to prohibit new coal, phased out of existing coal-fired units. Before the end of 2020, the province basically eliminated 35 tons of steam / hour and coal-fired boilers.

2, all cities and counties to complete the "high-pollution fuel combustion zone ban" before the end of June 2019 delineation and adjustment. In the combustion zone ban, prohibit the sale, burning polluting fuels. Within the province burning petroleum coke is prohibited. Oil coal quality sampling to establish a regular mechanism.

3, to carry out comprehensive improvement of industrial furnaces, phasing out non-compliance of industrial furnaces, industrial furnace to promote the use of electricity, natural gas and other clean energy or central heating.

4, the full implementation of the construction of urban gas engineering, gas propulsion countryside village "gas on behalf of firewood," to build a gas pipeline network covering urban and rural areas. Demand planning and construction of a number of gas-fired generation projects.

5, to promote the transformation of low nitrogen and ultra-low emissions retrofitting existing gas boiler biomass boilers. Low NOx combustion pollution control measures in new clean energy boiler fueled with natural gas should be used.

Good hot water ship vacuum tube 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.
