The origin of the name "ultra-low emissions"

　　The concept of "ultra-low emission" was first proposed by zhoneng group in 2011.In 2012, zhoneng group began to conduct extensive research on domestic and foreign advanced technologies for pollution treatment of coal-fired units.In 2013, zheneng group took the lead in the construction of "ultra-low emission of coal-fired units" project in China. On July 19, 2013, the feasibility study report of "ultra-low emission of coal-fired units" project of zheneng group was approved by zhejiang provincial environmental protection department, provincial economic and information technology commission, jiaxing municipal environmental protection bureau and other organizations.[3]

　　Definition of ultra-low emissions from coal-fired power plants air pollutants, there are many expression coexist, the original "near zero emissions", "zero emissions", "low carbon", "super clean", "below the gas turbine discharge standard", etc., have the personage inside course of study thinks, coal-fired units emission levels to achieve "super clean", "near zero" the difficulty of the state of the existing engineering technology can achieve large-scale promotion is difficult (), "ultra low emission" from the Angle of emission standards define concept, as a more scientific.[4]

　　At the 2015 China electric power development forum, liu zhitan, director of gas turbine research institute of guodian scientific research institute, came to the conclusion after a lot of comparison and data analysis: "we should be realistic and scientific in naming."The concepts of 'near-zero emissions',' ultra-clean emissions' and 'gas turbine emissions' are not rigorous and scientific, and the concept of' ultra-low emissions' is recommended."In March 2015, the government work report of the third session of the 12th National People's Congress explicitly called for "promoting the transformation of coal-fired power plants to achieve ultra-low emissions".In December 2015, the state council decided at an executive meeting to fully implement ultra-low emissions and energy-saving renovation of coal-fired power plants by 2020.
