In order to avoid haze again in the autumn and winter season, China's coal-fired power generation industry is accelerating the "green revolution."
According to China's official plan, by 2020 to fully implement the coal-fired units ultra-low emissions and energy-saving transformation, significantly reduce coal consumption and pollution emissions, the eastern and central regions to advance to 2017 and 2018 standards.
The so-called "ultra-low emissions" is to strictly control the production process of waste generated by the waste, to reduce the state close to zero; on the waste had to be discharged to be fully utilized. At present, China's five major power generation group is concentrated in the central region to deploy "ultra-low emissions" strategy, many power generation companies have begun "ultra-low emissions" pilot work.
Taiyuan Taiyuan, located in the main city of Taiyuan Taiyuan second thermal power plant, was founded in 1956, after the founding of new China in North China put into operation the first high temperature and high pressure thermal power plant. After upgrading, the plant to achieve economic and environmental protection of the win-win situation.
In April 2015, Shanxi Province Governor Li Xiaopeng asked Taiyuan two power plants six, seven four coal-fired units ultra-low emissions into the 2015 plan to synchronize.
"Datang Taiyuan two plant director Liu Xuedong told reporters that the plant is located in the city on the wind, the environmental protection is the government's request, it is the inevitable choice for the survival and development of enterprises." If not early transformation, it may be eliminated.
Transformation of the road is not good to go, to complete the transformation at the same time does not affect the winter heating, this commitment to the city of Taiyuan, nearly one-third of the heating area of the power plant is even more difficult.
Liu Xuedong said that in order to ensure the completion of the transformation on schedule, the plant innovative ideas, identify the transformation program, for the four units were designed denitrification system, desulfurization system, dust removal system, monitoring system transformation program. After efforts, Taiyuan two power plants only 111 days to complete the four units of ultra-low emissions transformation work, and in the year passed the official acceptance.
At present, the performance of ultra-low emissions transformation gradually. Environmental protection department monitoring data show that the transformation of Taiyuan two power plant after the four units of pollutant emission index is better than the first class of ultra-low emission standards in Shanxi Province limit requirements, that is, dust emission concentration of less than 5 mg, sulfur dioxide emission concentration of less than 35 mg , Nitrogen oxide emission concentration of less than 50 mg.
Annual use of hours 4000 hours, the plant can reduce emissions of 300 tons per year, 3200 tons of sulfur dioxide, nitrogen oxides 980 tons.
Transformation also brought economic benefits. According to Liu Xuedong introduced to upgrade the transformation of four units, Taiyuan Electric invested about 115 million yuan. According to the relevant materials issued by the Economic Commission of Shanxi Province in 2016, each 30MW unit of the enterprise can obtain 192 hours of annual use of the hour award, the annual base electricity increased by 242 million kwh, which is converted into profit of about 35 million yuan. According to Shanxi Province and Taiyuan City, ultra-low emissions transformation policy, enterprises can also get about 90 million yuan of transformation funds subsidies. This is a business, the total investment in ultra-low emissions is not large.
Today, China's coal-fired power generation industry for the control of pollutant emissions, has been walking in the forefront of the major coal consumption industry. A new round of coal-fired power generation "ultra-low emission" technology to promote, will further strengthen the coal-fired units on the control of pollutant emissions, to help regional energy consumption transformation and upgrading.
