Recently, we learned, Zhangbei County, Hebei Province to speed up the transformation of low-nitrogen combustion, gas-fired, Zhangbei County Environmental Protection Agency issued the "Notice on nitrogen oxide gas boiler governance", the transformation of the way around the gas boiler, the transformation of technology formalities to conduct a comprehensive explanation of propaganda, mobilization of Zhangbei above a certain size gas boiler units to actively participate in low-nitrogen transformation.

In order to ensure the smooth progress of work, the EPA developed a grasp of leadership, and a series of regular briefings on the system, arrange for the transformation of real-time tracking progress, personally led by the leaders in charge of the transformation of the construction-site supervision, to solve various problems during installation accelerate the transformation progress of the project. To date, more than 10 tons of steam Zhangbei natural gas boilers have been completed the transformation and detection of nitrogen oxide emissions, emission concentration all the stabilizing reached 30mg / m³ or less, over-done.

To protect the subsequent reconstruction work in depth, Zhangbei County township organization, the relevant units of the county with a comprehensive Mo Pai, gas-fired, gas-fired boilers for each specific model boiler unit, whether used and other basic information has been verified, the establishment improve the work ledger; to ensure that the base number is accurate, targeted work, Zhangbei arrange strengthen docking with the gas company, promptly verify the perfect new gas boiler archives, ensure the follow-up task of transformation clear, exhaustive renovation project. At the same time, combined with the actual development of the Zhangbei gas boiler compliance programs to lay a solid foundation for the comprehensive promotion of this work next year.

State supervision policy vacuum boiler is what vacuum hot water boiler with high efficiency, energy saving, safe, fast installation, versatile features, what state supervision policy vacuum boiler is? In May 2002, the State General Administration of Quality Supervision, Inspection and Quarantine (SAQSIQ) issued a document clearly defines the vacuum boiler: pressure vacuum phase transition boiler circulation system is lower than the atmospheric pressure. So there will be no explosion. Manufacturers should be manufactured in accordance with standard vacuum phase transition boiler, and bear the legal responsibility to notify the user (including boiler installer) safe use, and to ensure that the boiler system in use is always in a vacuum state. Vacuum phase transition boiler installation unit installation quality to meet the requirements of the production company responsible for the installation. Vacuum phase transition boiler installation meets the above specification, is not required by the boiler quality supervision and administration technology, pressure vessel safety watchdog confirmed, it does not require registration procedures for the use and other related issues. Vacuum hot water boiler water temperature can not provide hot water for different purposes, such as central air conditioning hot water, sanitary hot water, hot water process plant, schools, hotels, offices, etc., it is very suitable for use in these places. Fang fast vacuum condensing boiler thermal efficiency of up to 104%, full Chinese control, multi-level access control system to ensure the safe operation of the boiler, without losing flexibility.

What are the characteristics of vacuum boilers?

Vacuum phase change boilers in the industry are usually referred to as vacuum boilers. Professional vacuum boilers form a negative pressure vacuum environment within the enclosed furnace body. There is no danger of expansion and explosion because a vacuum boiler creates a low-pressure environment with little air, and then uses water to boil at a low temperature to produce steam. As a result, it is now commonly used in higher elevations. Let's find out what the features of the vacuum boiler are.

1, the vacuum boiler will not corrode because the internal structure of the vacuum boiler is negative pressure vacuum state, so it is completely isolated from the atmospheric pressure, so the pump pumps configured by the various units of the boiler will continuously discharge the steam from the unit. It does not corrode the internal structure, so vacuum phase change boilers perform fairly well in terms of durability.

2, safety and reliability are different from ordinary atmospheric pressure boilers. Because vacuum boilers pump air out of the inner container to form a vacuum environment, the furnace body does not work under the vacuum body in the course of use and will not be expanded by heat. It is not a pressure vessel, so there is no risk of explosion. At the same time, if the pressure increases due to faults or other perceived factors, the vacuum pressure switch automatically cuts off the power supply, so vacuum boilers are more reliable than other types of boilers in terms of safety.

Select vacuum boiler quality four reasons for people's lives improve, they also contributed to the gradual increase of the number of required hot water, a common boiler maintenance is more troublesome because it uses large tonnage; therefore, in this case, a boiler launched a new trend that is creating a vacuum boiler, it is called the new trend in the field of civil heating, and favored by the users as well as national attention. So why are more and more users will choose to vacuum boiler it? This is mainly for the following four reasons: 1, safe and reliable operation of the boiler during operation when the vacuum pressure inside it remains under vacuum. Regardless of the heat exchanger in the boiler due to external pressure leaks, because the operation or failure can not exceed the atmospheric pressure at the outside, its various vacuum pressure switch, will automatically cut the power supply. Moreover, the stable performance of the vacuum boiler also has advanced technology, the failure of all automatic water level, low voice alarm system can automatically cut the power supply and inform the user, to avoid great losses because of excessive water caused. 2, the structure is compact and easy to install by vacuum boiler structured design, easy to transport and make the product, because of the small volume of the unit, in a small space so that multiple units can be used in parallel but it also has unique environmental features. 3, vacuum boiler applicability due to the special design of the structure is formed, may be provided at the same time hot water and the temperature difference between the multiplexer to satisfy their demands for hot water supply. And continued insulation effect is obvious, the burner is also the use of imported products, especially for low-lying areas. And from commissioning to run the whole process does not need to check, of course, does not require the holder of the Boilermakers. 4, because of its long life vacuum boiler interior is integrally sealed atmosphere, and at runtime, the intermediate oxygen precipitation medium is water, and promptly discharging furnace, the furnace so long oxygen corrosion does not occur, nor will place a long time to generate internal boiler fouling difficult to clean, thereby increasing the life of the boiler use. It is because of a variety of vacuum boiler has so many features, making it more smoothly during operation, and operator can be more time-saving, so it can be widely used in so many places, is not close there are structural aspects of the advantages of using a full-featured, in order to gain certain advantages in various industries.
