Vacuum gas boiler introduce vacuum gas boiler Product Description: Vacuum gas boiler is the use of water at different pressures, the boiling temperature characteristics vary to carry out the work. At one atmosphere, the boiling temperature of water is 100 deg.] C, and under a pressure of 6mmHg, the boiling temperature of water was 4 ℃. Vacuum hot water unit is operating in the pressure range 200mmHg ~ 500mmHg, the corresponding water temperature was 66 ~ 88 ℃, hot water under pressure in the vacuum of the work unit, the combustion temperature of the heat medium water temperature rises to saturation, and generating steam in the water of the same temperature. At this time, through the heat exchange (heating or hot water) inside the water, the cold water in the steam tube outer tube is heated in hot water, and passed to the user, and the water steam outside the pipe were cooled and condensed back to water is heated water drops , thereby completing the cycle. The main features; vacuum hot water units always run under negative pressure, never inflated the risk of explosion, with safety and reliability atmospheric pressure boiler has unmatched; built-in stainless steel heat exchanger, heat transfer efficiency, water quality cleaning; built rope stream smoke tube sheet, increasing the effect of heat transfer, so that a more compact structure; imported burner, combustion efficiency, noise, low emissions, to achieve the requirements for a class Country; integral with a square configuration, overall spraying, shape compact appearance. Smoke tube equipped with a helical spoiler, heat strengthen, improve boiler efficiency and reduce operating costs. Indirect heating: main body of negative pressure, the system pressure; large furnace technology: effective to increase the area of ​​heat radiation unit, reducing the NOX emissions; high water boiler water, inside the body to ensure that never scaling, corrosion. Boiler and heat exchanger integrated design, saves space and greatly reduce floor space. Shell type using three return all wet back structure, dynamic heating, heat sufficiently. Low temperature boiler operation under negative pressure, safe and reliable. Automatic control system, no special duty. Imported burner, combustion efficiency, noise, emissions low. Unique pulse level detection circuit structure, reliable performance. Inlet / outlet water temperature display makes it easier to grasp the boiler operating conditions and systems. High centrifugal glass wool insulation using multi-layer, heat loss. Protection: 1, the boiler has a voltage high, ultra-low protection, when the supply voltage exceeds the normal range, the alarm and automatically cut off the power boiler. 2, the boiler has a temperature sensor fault protection, each boot, the boiler control system first detection sensor condition, such as abnormal boiler is automatically cut off power and alarm. 3, the boiler having a water alarm function: When the boiler water level is below the safety level pot, the boiler automatically cut off power and alarm. 4, the burner flame failure alarm 5, overpressure sound and light alarm 6. boiler burner motor overload, fault protection 7. Automatic shutdown protection, as follows: a) a burner failure automatic shutdown, manual reset b) very low gas pressure automatic shutdown, manual reset c) automatic overpressure boiler shutdown, manual reset power d) of the safety interlock device interrupt automatic shutdown, manual reset heating gas boiler

Recently, we learned, Shaoxing City, Zhejiang Province People's Government Office issued the "coastal city 2018--2019 autumn and winter tackling air pollution comprehensive management action plan", as follows.

Less adopt comprehensive measures to reduce coal total coal consumption, coal consumption in 2018 to ensure that the total amount of negative growth. New non-owned coal-fired units, the implementation of new large-scale coal-fired units and coal consumption capacity equal or reduction alternative.

Optimize the use of natural gas structure, in principle, to new natural gas cogeneration and gas chemical projects, gas will adhere to the reform, orderly manner "coal to gas" project.

Carry out boiler (with tea furnace, operating a stove, grain storage and drying equipment, coal-fired facilities) an intensive investigation to establish accounting and inventory management, to develop a comprehensive remediation program in accordance with the unified deployment requirements boiler city, according to the law in accordance with regulations to increase fuel coal boiler out of efforts to achieve all cleared 10 steam tons / hour and coal-fired boilers to prevent high-polluting fuel boiler rebound has been eliminated. Boiler registration strictly prohibit new steam per hour 35 tons / hour of coal-fired boilers, coal-fired boilers new emission concentration to meet ultra-low emission of air pollutants, strict control of new biomass boilers, coal-fired boilers embodiments and low nitrogen urban built-up area of ​​ultra-low emission biomass boilers transformation.

Enterprises in the selection of vacuum hot water boiler needs to pay attention to what vacuum gas hot water boiler as the future development trend of the civilian boiler, safe, free inspection, easy to operate, by the majority of boiler users. Like traditional boiler, the boiler in the selection process, in addition to quality and price factors, but also need to pay attention to the following factors: fuel vacuum hot water boiler: When selecting a vacuum hot water boiler, first thing to consider is what fuel combustion. This gas combustion boiler both, but also light diesel oil combustion. In terms of environmental protection and convenience, it is recommended to use natural gas procurement business as boiler fuel. Evaporation in vacuo of the hot water boiler: may be referred to herein evaporation boiler load, i.e., steam or hot water required by the user, the unit may be t / h that the rated capacity of the vacuum hot water boiler is 0.56t / h in vacuo. hot water boiler heat exchanger: compared with a conventional boiler, vacuum hot water boiler heat exchanger inserted in the upper half of the vacuum vapor chamber. Select the heat exchanger needs to be determined according to the user a boiler. It is divided into three heat exchangers, ABC, heating, hot water, hot water process for different purposes.

Why vacuum boiler 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.
