To continue to improve air quality and protect people's lives and health, Hainan Province, issued a "Hainan Air Pollution Prevention Regulations" (hereinafter referred to as "Regulations"), a clear implementation of the total coal consumption control system, and gradually reduce the amount of coal consumption, phase out existing coal-fired units. "Regulations" since March 1, 2019 into effect.

"Regulations" put forward specific requirements for coal and other energy pollution control.

A prohibited import, sale and burning of coal does not meet quality standards; prohibited the import, sales do not meet standards of quality petroleum coke; prohibition of burning petroleum coke. Above the county level department in charge of market supervision and management need to be strengthened coal, petroleum coke quality management, from time to time on coal, petroleum coke quality sampling.

Second, the people's government above the county level market supervision and administration departments shall, jointly with relevant departments in charge of the environment, industry and information technology, etc. According to China's Hainan Province and the relevant provisions to strengthen the supervision and management of boiler production, import, sale, use, etc., do not compliance with environmental standards or requirements shall not manufacture, import, sale and use. Phasing out coal-fired boilers. Existing clean energy such as natural gas-fired boilers, furnaces, low NOx combustion should be completed within the prescribed period of transformation of the people's governments above the county level department in charge of the ecological environment. New clean energy such as natural gas-fired boilers, furnaces and other facilities shall pollution control measures such as the use of low NOx combustion.

Third, the central heating has been implemented for the work (production) business park, a ban on new construction, renovation, expansion of decentralized heating boilers, heating boilers should be dispersed in the original city, county, autonomous county people's government department in charge of market supervision prescribed period in the demolition; work not yet implemented central heating (production) business park has heating demand should be in the city, county, central heating implementation as soon as possible within the time limit prescribed Autonomous County people's government department in charge of market supervision and management, and removal of the original dispersion heating boilers.

1, the safety valve should be mounted vertically in a high position in the pot business, set box.

2, between the safety valve and the drum or header, not equipped with access to the steam outlet pipe and the valve.

3, the lever-type safety valve should prevent movement of the self-apparatus and the weight limit leverage deviant guide tube, a spring safety valve should lift and handle means for preventing movement of the adjustment screw is screwed lightly.

4, the rated steam pressure less than or equal to 3.82MPa gas steam boiler safety valve throat diameter of not less than 25mm; power greater than the rated steam pressure 3.82MPa boiler safety valve throat diameter not less than 20mm.

5, the safety valve and coal-fired steam boiler tubes, the cross-sectional area not less than the cross-sectional area of ​​the valve inlet. If several valves installed together with a short tube directly connected to the drum, the cross-sectional area of ​​the passage should not step short tube to 1.25 times the area of ​​all the exhaust valve.

6, the safety valve should normally be installed exhaust pipe, exhaust pipe should be through a safe place, and there is sufficient cross-sectional area to ensure the smooth flow of exhaust.

7, the safety valve exhaust pipe at the bottom should have received a place of safety posturing of drainage pipe, the exhaust pipe and drainage pipe not allow the installation of the valve.

8, rated evaporation to 0.5t h coal-fired steam boiler /, at least two safety valves installed; Rated evaporation 0.5t h less than or equal to electric boiler /, mounted on at least a safety valve.

Chemical prevent high temperature corrosion of boiler for sale for chemical industry waterwall boiler chemical improvements to prevent high temperature corrosion improvements waterwall 1, using an anti-art windshear main principle is offset by a spray angle of air flow injection port, and the original jet forming a motion , the opposite direction of rotation, in tangentially running smaller diameter, due to the opposite running direction of the initial movement of the main gas flow direction of the gas flow in the furnace after the anti-wind shear, the pulverized coal injected hindered high-temperature air upstream of the primary air flow and the time, the pulverized coal injection speed is reduced rapidly, enhancing coal dead time in high temperature zone, to enhance the combustion efficiency of pulverized coal. By using an anti-wind shear can effectively prevent high temperature corrosion phenomena, and can enhance the ability to stabilize combustion in the boiler furnace, reduced coke boiler case, as shown in FIG. 2, using the technology of Side by side wind technology is mainly on the high temperature zone waterwall corrosion or high temperature corrosion installed upstream of the injection port area, and ejecting the air in the furnace boiler. Technology is mainly employed side air can be controlled in the high-temperature reducing gas corrosion area, enhanced oxygen content in a local range. 3, to improve the control operation to take excess air coefficient increases, a plurality of coal mills is not put into operation at the same time, reduce the coal particle size, increase the air preheater ash fouling preventing plugging of equipment and operation control systems such as high temperature measures to prevent High temperature corrosion phenomena.

Why low nitrogen gas boiler for sale for chemical industry in the market, whether it is more popular hotels in heating, plant operations, or daily life, etc., these places need to use gas burners. Combustion gas released a lot of atmospheric pollutants. Coal makes use of a wide range of atmospheric environmental quality of our country is getting worse, to control air pollution in the form of very grim. Starting from coal, governance atmospheric environment, without delay. According to fast boiler boiler industry for many years engaged in the conclusions read: more and more enterprises put more clean and environmentally friendly low nitrogen gas boiler. Fast boiler you anything in detail, low nitrogen gas boiler in the market even more popular. 1, compared to the traditional coal-fired boiler, a low nitrogen gas boiler is generally more cost-effective conventional coal-fired boiler is filled manually into the direct fired furnace for combustion, which combustion produces very large sulfides, dust, etc. harmful substances discharged into the atmosphere pollution index high; but also need to manually add the fuel, time-consuming and labor-intensive, more harm than good. Low nitrogen gas boilers use natural gas as a clean fuel, only gas pipeline and turned good start to complete combustion, it can be said to be very convenient. Boiler also joined the low nitrogen treatment technology, flue gas emissions to less negligible, is also favored by the environmental protection department equipment. 2, most importantly, natural gas low nitrogen boiler environmental clean gas low nitrogen boiler most dominant feature is the external energy saving, pipes low nitrogen boiler by using the thermal conductivity is relatively low glass wool heat insulation layer, thereby reducing boiler the heat loss, to achieve energy saving effect. FGR premix flue gas recirculation and low NOx combustion technique, the situation is improved by the combustion of the fuel, a truly effective in suppressing the generation of nitrogen oxides. 3, natural gas low nitrogen boiler using more advanced technology, natural gas low nitrogen boiler thermal efficiency higher fast boiler through the use of flue gas condensation heat recovery technology, the high temperature flue gas in the latent heat and the sensible heat portion utilized, the thermal efficiency can be improved 20 about%, reaching more than 103%, significant savings in the late running costs, but also reduce operating costs. Combining these three points, we can see that low nitrogen gas boiler is the best choice, but also the most sensible choice. To promote the implementation of environmental protection plan, accelerate the improvement of air quality, speed up the process of using low nitrogen boilers to reduce emissions of nitrogen oxides, nitrogen oxides and reduce PM2.5 due to the formation of the secondary reformer. Give us more space to control air pollution.
