Central China's Henan province has started to implement new emission standards to strictly cut atmospheric pollutants from coal-fired power plants, local media reported, citing the provincial environmental watchdog.
The new standards, going into effect on October 1, aim to realize extra-low emissions at coal-fired plants, thus greatly improve air quality in the coal-rich province, reported the Henan Daily.
Under the new standards, the emission caps regarding soot, sulfur dioxide, nitrogen oxides, mercury and its compounds are 10 mg, 35 mg, 50 mg and 0.03 mg per cubic meter, respectively. All of the limits are lower than China's national emission standards.
So far, 144 coal-fired generating units under unified dispatch and 124 local generating units had finished upgrading and realized extra-low emission.
The provincial government plans to finish ultra-low emission upgrading to 86 coal-fired boilers (each above 65 T/h) this year.
Coal-fired generating units take up 95.9% of Henan's total installed capacity, and contribute 97.1% of the province's total power generation. They consume 45% or so of the coal consumed for industrial purpose in the province.
