Timetable for ultra-low emission of coal-fired units in Shandong
By the end of 2015, more than 30% of the total coal-fired power plants with over 300 thousand kilowatts and above completed ultra-low emission transformation tasks.
Before the end of 2016, the number of 100 thousand kilowatt and above coal-fired units to complete the ultra low emission transformation task is about 50%, and the number of 300 thousand kilowatt and above public coal-fired units to complete the ultra low emission transformation task is about 70%.
Before the end of 2017, the number of 100 thousand kilowatt and above coal-fired units to complete the ultra low emission transformation task is about 80%, and 300 thousand kilowatts and more coal-fired units complete the task of ultra low emission transformation.
By the end of 2018, all coal-fired generating units of 100 thousand kilowatts and above completed the task of transforming ultra low emissions.
"By the end of 2018, all coal fired units of 100 thousand KW and above completed the task of ultra low emission transformation, and all the 10 steam tons per hour of coal-fired boilers in the whole province completed the task of transformation." The reporter has issued the "guidance on speeding up the ultra low emission of coal-fired unit (boiler)" (hereinafter referred to as "guidance") from the Shandong provincial Environmental Protection Office, the provincial development and Reform Commission, the provincial economic and credit commission, the provincial finance department and the provincial Price Bureau five departments.
The guiding opinion points out that the ultra low emission transformation of coal burning unit (boiler) is actively promoted by the comprehensive application of economic policy, scientific and technological support and necessary administrative measures, focusing on the "2013~2020 years air pollution prevention and control plan of Shandong province", which "the environmental air quality of the province in 2020 is 50% better than that in 2010". Through the implementation of incentive policies, standardized environmental supervision, forced the transformation and upgrading of traditional industries, to promote the continuous improvement of atmospheric environmental quality in the province.
According to the reporter, Shandong province will vigorously promote the ultra-low emissions of coal-fired units (boilers), which will effectively improve the quality of the atmospheric environment, promote the transformation and upgrading of traditional industries, and accelerate the development of the environmental protection industry. According to the calculation of ultra-low emission transformation of coal-fired unit with 100 thousand kilowatts and above, 53 thousand tons of smoke and dust, 300 thousand tons of sulfur dioxide and 460 thousand tons of nitrogen oxides can be reduced every year in the province, and the efficiency of pollutant emission reduction is obvious. Through the promotion of ultra-low emission and strict implementation of the gradual and strictly regional atmospheric pollutant discharge standards, coal enterprises are forced to phase out small coal-fired units (boilers) with high energy consumption, heavy pollution and difficult treatment. At the same time, vigorously promoting ultra-low emissions for the province's environmental protection industry development, scientific and technological upgrading and third-party treatment of environmental pollution has created a good opportunity.
Unified standard, easy to be difficult in the first place
Monitoring and confirming in accordance with relevant technical specifications
It is understood that in order to deepen the prevention and control of air pollution, since 2011, Shandong province has explored and carried out the pilot work of ultra-low emission transformation of coal-fired units (boilers), and organized a gradual and strict regional air pollutant discharge standard, which was issued and implemented in 2013. The standard stipulates that in the core control area, by 2020 the coal-fired unit should reach the emission level of the gas turbine unit, and the development and application of the ultra low emission technology in Shandong province are stimulated by the standard compilation and implementation. Up to now, the province has built 17 ultra low emission coal-fired units, and 36 ultra low emission coal-fired generating units under construction.
"Guidance" determines the "unified standard, strict implementation; the first difficult, step by step implementation; scientific monitoring, performance review, award replacement, encourage advanced" principle of work.
It is clear that the emission concentration of the main atmospheric pollutants, soot, SO2 and NOx, is not higher than 5 mg / m3, 35 mg / m3, 50 mg / m3 respectively, and the nitrogen oxide emission concentration of the "W" type flame boiler is no longer under the ultra low emission transformation. More than 100 mg / m3. The emission concentration of the main atmospheric pollutants, soot, SO2 and NOx, is not higher than 10 mg / m3, 50 mg / m3, 200 mg / m3 respectively, and the concentration of NOx emission in key areas is not more than 100 mg / m3, respectively, after the ultra low emission of coal-fired boiler.
According to the different types and scales of coal-fired units (boilers), it is easy to implement them first, then difficult, and actively and steadily promote the ultra-low emission transformation of coal-fired units (boilers). After the transformation of ultra low emission of coal-fired unit (boiler), it should be monitored according to the technical requirements and technical specifications of ultra low emission monitoring in accordance with the method of measuring the weight of low concentration particulate matter in Shandong province's fixed pollution sources. Environmental protection departments should strengthen the performance audit of the operation level of ultra-low emission facilities, pollutant emissions and reduction efficiency to ensure that the ultra-low emission transformation achieves effective results.
For the coal-fired units (boilers) that have completed the ultra low emission transformation and through the performance review, the incentive policies such as "award replacement", electricity price subsidy, electricity incentive and differential discharge charge are implemented in accordance with the regulations, and enterprises are encouraged to implement ultra low emission reform as soon as possible and build up the efficiency at an early date.
Clear the schedule of transformation
Single 10 steam tonne / hourly boiler should be eliminated
"Guiding Opinions" determined that coal-fired units, coal-fired boilers to implement ultra-low emission transformation, small coal-fired boilers (furnaces) to implement environmental protection transformation.
By the end of 2015, more than 30% of the 300,000 kilowatt and above public coal-fired units in the province will have completed the task of ultra-low emission transformation. By the end of 2016, the number of 100 thousand kilowatts and more coal-fired units in the province completed the task of ultra-low emission transformation to about 50%, and the number of 300 thousand kilowatt and above coal-fired units to complete the ultra low emission transformation task reached about 70%. By the end of 2017, the number of coal-fired units with over 100 thousand kilowatts and above completed the task of transforming ultra-low emission to 8.
