waste heat recovery power plant boiler

Some time ago we learned that the Xinxiang City, Henan Province is located in order to further deepen the pollution gas waste heat recovery power plant boiler, reducing nitrogen oxide emissions, improving air quality, we launched a "campaign of Xinxiang City, pollution prevention three-year action plan implementation (2018-2020 Year) "(hereinafter referred to as" an embodiment "), as follows.

First, the implementation of the total coal consumption control

As of 2020, the city's coal consumption control at 13.04 million tons, the proportion of energy consumption control in less than 70%. Coal-fired power plants and strengthen the chemical industry, nonferrous metals, building materials and other key industries of coal consumption control, under the premise of protecting the power system security and stable operation of non-fossil energy generation within the city full consumptive, and actively absorb external calls.

Further promote high-pollution fuel combustion zone ban construction. Gradually expand Ⅲ fuels (coal and its products, including clean coal) combustion zone ban range, central heating and complete cleaning of coal bulk region designated as an alternative class Ⅲ high-pollution fuel combustion zone ban. Increase the combustion zone ban supervision, prohibition of bulk coal sales and hoarding, and severely punish violations of the ban management requirements combustion zone, the region has been completed to prevent bulk coal burning complex.

Second, comprehensive remediation coal-fired boilers

Adhere to the "source of governance, a total ban, focused, step forward" principle, and comprehensively promote the elimination of scattered coal-fired boiler (kiln) coal-fired furnaces and other industrial facilities, the renovation work. Before the end of December 2019, basically out of Xinxiang City, the administrative area of ​​35 steam tons / hour and coal-fired boilers, coal-fired boilers essential to retain, to achieve ultra-low emissions must be stabilized.

Third, actively develop renewable energy

Regions and the development of renewable energy, constantly optimize energy consumption structure, and gradually improve the urban proportion of clean energy use, and build a clean energy-based energy security system. By 2020, the proportion of non-fossil fuels in total energy consumption in the city of more than 7%.

Fourth, to enhance the level of natural gas utilization

Good job of marketing system storage capacity for natural gas. And strive to 2020, the proportion of total energy consumption of natural gas accounted for 10%. Strengthen joint cooperation with the West-East pipeline in northern branch and other existing, fully-use planning Sinopec Xinjiang coal gas "new Guangdong and Zhejiang," and so on through the pipeline from the city's strengths to enhance the capacity of natural gas reserves, counties 2020 (city), District of forming at least not less than three days of emergency reserve capacity average daily gas consumption to protect the administrative district, city gas companies and large users uninterruptible form of not less than 5% of its annual gas consumption of the emergency gas storage capacity.

Fifth, the effective promotion of clean heating

Continue to promote clean heating pilot city construction work. City and county built-up areas to development of central heating based, improvement and transformation of the heating pipe network, a substantial increase in the rate of central heating, the first to achieve clean heating rate of 100%.

Sixth, vigorously promote the construction of central heating

Industrial central heating full coverage. Accelerate the integration of industrial parks (industrial parks) existing heat points, to promote the heating pipe network construction, the gradual elimination of the industrial park (industrial parks) central heating blind spots. Existing types of industrial parks and industrial clusters should be implemented cogeneration or Central Heating, industrial enterprises into the central heating, decentralized heating phase out the industrial park to ensure the realization of "a zone a heat source."

Fuel processing gas waste heat recovery power plant boiler gas boiler using natural gas leak is natural gas, in order to ensure security, we later discovered natural gas boiler leaks we want to timely treatment, so as to ensure the safety and security of the people of the boiler, then you introduce small series about safe handling methods. 1, in strict accordance with relevant regulations and procedures boiler room gas leak tissue processing; timely, relevant departments heating company to contact the gas company needs to cut off the gas supply must be cut off, need replacement of natural gas according to the provisions of certain replacement; 2, need to go through certain formalities flare according to the provisions apply, you need to be sure to appoint professional construction team of qualified professional team of maintenance; 3, for a variety of possible spills, organized the compilation of relevant good treatment program, contingency plans, and make each emergency plan drills; be prepared to handle special materials spill, fire emergency reserve supplies, detection tools, etc.; 4, processing gas boiler plant leak to send a full-time security officer in charge of the scene, the relevant personnel related technical tests; has been dealt with to ensure the best site work completed, materials clear, serious and ready to fill in information technology. And that knowledge about the safe handling of gas leaking gas boiler method, I believe you must have a lot of harvest it, I hope this can help you to better avoid the occurrence of such phenomena.

Some issues with the Pulverised Coal waste heat recovery power plant boiler:

1. Coal is combusted at temperatures of about 1600-1800 deg C. At such high temperatures, NOx, which is a notorious pollutant, is formed.

2. SOx pollutants are carried away in flue gases, which condense to form highly corrosive sulphuric acid at temperatures around 140-160 deg C. Thus, the exhaust temperature has to be maintained above this temperature to avoid large-scale corrosion of boiler water tubes. This limits the boiler energy extraction efficiency and constitutes the largest heat loss from the boiler.

Fang fast gas condensing waste heat recovery power plant boiler which features

1, the steam boiler burner gas supplied by well-known manufacturers in the world, according to the automatic combustion controller instructions, stop, independent of the control box has a number of security, safety and stable performance, low maintenance;

2, advanced automatic steam boiler controller, Chinese LCD screen, the man-machine interface, the user simply easily set, i.e., according to user requirements boiler start and stop, load adjustment, automatic water supply, such as automatic operation. Boiler fully functional, complete protection, easy to operate, safe, reliable, self-diagnostic function. Boiler operation in the event of abnormal combustion is automatically interrupted, audible alarm;

3, vertical steam boiler burner set under way, double return configuration, fuel combustion, boiler stable; inserted spoiler smoke tube, smoke slow speed, increase heat transfer, a high thermal efficiency, reduce user cost;

4, horizontal steam boiler shell type three return all wet back downstream pyrotechnic tube structure, the use of economic, waveform threaded pipe and furnace structure and improve the strength of heat absorption of the boiler, the heating surface needs thermal expansion;

5, in strict accordance with the present boiler "Steam Boiler Safety Supervision", JB / T10094-2002 "industrial boilers general technical conditions", JB / T1619-2002 "boiler manufacturing technology conditions potshell" requirements, design, manufacture, monitoring inspection to ensure good quality of boilers, achieve low energy consumption, high thermal efficiency, stable pressure, gas and quantity, the economic use;
