d Frequency of revision of my country’s emission standards Much higher than other countries. From the promulgation of the first emission standard in 2016 to 2018, it has undergone a total of revisions. The "Trial Standards for Industrial Waste Emissions" of 2016 stipulates the hourly emission limits for the entire plant based on the number of chimneys and the height of the chimneys for smoke and dust emissions from coal-fired power plants. Most power plants use mechanical dust collectors such as cyclones and multi-tubes, and the dust removal efficiency is generally lower than %.
The "Emission Standards for Air Pollutants from Coal-fired Power Plants" (-) in 2016 determined the emission limits based on the technical level of three-field electrostatic precipitators and high-efficiency hydraulic precipitators, and the dust removal efficiency was greater than %.
d was revised to the "Emission Standards for Air Pollutants from Thermal Power Plants" (-) and began to be divided into periods marked by the year of power plant construction or environmental impact assessment approval, and the emission limits and dust removal efficiency were determined to be greater than % based on the technical level of the third and fourth electric field dust collectors.
d was revised to the "Emission Standards for Air Pollutants for Thermal Power Plants" (-) and the readjustment period was based on the technical level of four-field, five-field high-efficiency electrostatic precipitators and bag dust collectors to determine emission limits and dust removal efficiency greater than %.
Revised in 2015 as the "Emission Standards for Air Pollutants from Thermal Power Plants" (-), the period was again readjusted and the emission limits were determined based on the technological development level of electrostatic precipitators and bag dust collectors with five electric fields or higher, taking into account the The dust removal efficiency of the wet desulfurization system is greater than .%.
