superheater of high pressure boiler
Some time ago we learned that the Xinxiang City, Henan Province is located in order to further deepen the pollution gas superheater of high pressure 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 thermal efficiency of the superheater of high pressure boiler instructions and the controller work steps: for this kind of boiler oil-fired boiler, mainly through the following specific questions to learn their work, and gives specific answers thereto, so that we have to learn content, and there is fully understand and appreciate. At the same time, also can through this article, to increase their expertise in this area, and thus, a new harvest from the study. 1. oil-fired boiler in its pollutant emissions standards, which one? Oil-fired boiler, its pollutant emissions standards, for "Boiler Air Pollutants Emission Standard" GB13271-2014 this one. Moreover, this standard, not just for this kind of boiler oil-fired boiler, which also applies to coal-fired and gas-fired boilers, and steam boilers, hot water boilers and organic heat carrier boiler three boilers.
When it is detected in the case of the controller energized, function to start the antifreeze temperature below 3 ℃, start heating heater; when the detected temperature is increased to 8 ℃, the heater stops heating; Memory: fuel steam superheater of high pressure boiler antifreeze function function: set various parameters with memory function, power off and then on do not have to re-set. After the fuel steam boiler time setting, after a power failure can also be run as usual, do not correct the time after power again. Fuel steam boiler temperature control: If the set temperature does not power up, the system operates in the default parameters 50 ℃; if the set temperature, the set press operation. When turned on, the controller detects that the heating temperature is lower than the set temperature 8 ℃, by setting the gear, turn the heating tube, the heating temperature when the detected temperature is equal to higher than the set power off, stop heating. The temperature was slowly lowered below the set temperature 8 ℃ again to turn the heating tube, temperature reached this cycle. Gas steam boiler heating surface scale.
2. Maintenance and treatment method of Boiler during shutdown of Hot Water Boiler. full water preservation treatment:
This is a common processing method. Especially suitable for parts that cannot be drained, even if the desiccant is added, there are local wetted parts, as well as requirements for emergency operation of the situation, and so on. This method is commonly used in the methods of ammonia-filled water preservative and nitrite preservative. Under various preservation treatments, the concentration of the preservative is very important. In addition, during intermittent injection, due to the natural circulation of waste heat of boiler water and forced circulation of circulating pump at the same time, the concentration is uniformly mixed.
