Industrial production is inseparable from boiler advantagess, emission control of atmospheric pollutants boiler air pollution control in Shanghai to expand and intensify the focus of the project. Currently, Shanghai Industrial boilers alternative clean energy has been completed, nitrogen oxides (NOx) emissions of major pollutants as a boiler, the boiler due mostly low shelf emission source of ambient air near the ground and ozone greater PM2.5 influence, therefore, this release the new standard, the boiler will be low-nitrogen transformation, improve Shanghai air quality, protect people's lives and health and other aspects demand a strong thrust of great significance. Throughout the country, Beijing, Tianjin and other places have started low-nitrogen transformation boilers for low-nitrogen transformation has a more mature technology reserves. Based on the above considerations, for the effective control of NOx emissions from boilers, to further deepen cooperative control of PM2.5 and ozone, according to the standard first, to further accelerate the transformation of governance principles, it is necessary once again to revise the standard boiler.

According to local environmental standards and revision procedures, the Municipal Environmental Protection Bureau held a meeting to hear the relevant departments, enterprises and the opinions and suggestions of experts, and in 2017 August 4 to September 15 in the online open standard full text to solicit public opinion. At the same time the Ministry of Ecology Environment solicit written opinions Municipal Development, City Commission by letter and other related commissioned Bureau, industry organizations and boilers, production units and other enterprises. Municipal Environmental Protection Bureau and the Municipal Quality and Technical Supervision on January 19, 2018 organized the expert technical review meeting, the panel agreed that standards through technical review. Approval by the Municipal Environmental Protection Bureau and the Municipal Quality and Technical Supervision audit report to the municipal government.

The new standard has been revised for several aspects, one is no longer on the "central heating boiler and the nominal amount of evaporation less than 65t / h boiler cogeneration" provisions alone time; the second is to simplify the original class standard boiler merged into " gaseous fuel boiler "and" boilers "categories; are three different degrees of contamination tightened limits particulate matter, sulfur dioxide and nitrogen oxides; four new boiler is implemented from the date of implementation of this standard, the boiler given a transition period of about two years.

New standards for gaseous fuel boiler particulate matter, sulfur dioxide and nitrogen oxides are applied strict limits, but mainly considering the control of nitrogen oxide emissions, and further improve air quality. In the transition period boiler (1 October 2020) to limit nitrogen oxide 150mg / m³; after a transitional period of 50mg / m³. Date of implementation of new boiler nitrogen oxides from standard starting execution 50mg / m³ limit. Taking into account the comprehensive utilization of straw in Shanghai, biomass fuel boilers follows the standards of the original project control and limit requirements.

What should we pay attention to when buying gas-fired boiler advantages

Undeniably, the maintenance of excellent quality of professional gas boiler for many years also makes more users begin to have more interest in its use. At the same time, it also makes people pay more attention to the quality identification of gas fired boiler. In order to find the right gas-fired boiler equipment, you need to be able to pay attention to the following aspects at the time of purchase.

1. In most cases, concerned about boiler quality, users with certain technical thinking will first pay attention to the boiler quality when buying safe and reliable gas-fired boiler equipment. On the other hand, the performance characteristics and core technology of gas-fired boiler can also directly reflect the excellent quality of gas-fired boiler, which can be evaluated from the product information and qualification honors provided by the merchants, on the other hand, the performance characteristics and core technology of the gas-fired boiler can also directly reflect its excellent quality.

2, pay attention to the boiler cost-performance ratio can be sure that the gas-fired boiler cost-performance ratio is also a focus in the purchase of an aspect, because high cost-effective boiler equipment must be both excellent quality and affordable two advantages of the characteristics of the two advantages, The benefits of such a choice not only give users a sense of real value for money, but also avoid questions about how much more gas-fired boilers cost more than coal.

3, pay attention to customer word of mouth in addition, when choosing a good gas boiler, you should also refer to the past customer's specific evaluation of this equipment, and these contents are actually available on the boiler brand's official website, At this time, we can get a comprehensive understanding of the professionalism, usability and safety of gas-fired boiler equipment through the real evaluation of these past customers, and then we can find out the better boiler equipment in the word-of-mouth as soon as possible.

Gas fired horizontal style and low pressure gas steam boiler advantages is designed specifically for the requirements of the commercial market and is available in sizes ranging from 1-20 tons for 0.7-1.6 MPa steam pressure.This type boiler also can use diesel oil,light oil or heavy oil as fuel.

If a single burner extinguishes, there may also be a deviation in the center of the furnace flame, and the air pressure of the extinguished burner may change. If the fuel supply is interrupted, the oil pressure or pressure indication of the extinguished burner may decrease to zero, while the fuel and gas pressure of other operation burners may rise. After the occurrence of the above situation, the boiler advantages must be handled in a timely manner to ensure the safety of use.
