      Huang Xuenong, Director of the Electricity Department of the State Energy Administration, recently said that in order to further improve the clean and efficient development level of coal-fired power, China's coal-fired power industry has vigorously implemented ultra-low emissions and energy-saving transformation in recent years. By the end of 2017, the coal-fired power units that have reached the ultra-low emission limit have reached 700 million kilowatts, accounting for 71% of all coal-fired power units; the total energy-saving transformation of coal-fired power units has been completed 604 million kilowatts, and 96% of the transformation tasks have been completed by 2020. China has built the largest clean coal power supply system in the world.

      Huang Xuenong is on the 13 day of the 2018 China electric coal high-end forum introduced above.

      "Over the past decade, we have eliminated more than 110 million kilowatts of small thermal power units with high pollution and energy consumption, greatly optimized the coal-fired power installation structure, and significantly increased the proportion of clean, efficient and advanced coal-fired power units. In recent years, the newly commissioned coal-fired power units are basically advanced units with large capacity, high parameters, high efficiency, high water-saving and ultra-low emission. Huang Xuenong said.

      It is understood that the world's first 600 MW supercritical coal-fired unit, 1 MW supercritical unit and 600 MW supercritical circulating fluidized bed unit have been put into commercial operation in China. According to the data of the State Energy Administration, the proportion of coal-fired power units with 600 MW or more has increased to about 45% by the end of 2017.

      According to the statistics of China Electric Power Enterprise Federation, the total emissions of SO2, NOX and soot in China's electric power industry have dropped from 29.5 million tons of peak value to 2.6 million tons in 2017, a drop of 92%, and the coal consumption of coal-fired power units has dropped to 312 g/kWh in 2017.

      Huang Xuenong said that there are 150 million kilowatts of coal-fired power units below 300,000 kilowatts. These units play the role of heating or power grid support. More powerful measures are needed to promote the elimination and shutdown of backward coal-fired power units that do not meet the standards. The State Energy Administration and other three ministries and commissions jointly issued the "Coal and Electricity Energy Conservation and Emission Reduction Upgrading and Renovation Action Plan (2014-2020)". The recent "Three-year Action Plan for Winning the Blue Sky Defense War" issued by the State Council has put forward higher requirements for coal and electricity emissions.

      "The next step will be to continue to phase out backward coal-fired units below 300,000 kilowatts that fail to meet the standards of environmental protection, energy consumption and safety. The ultra-low emission transformation of coal-fired power units in the central region should be completed in 2018 and in the western region in 2020. Huang Xuenong said.
