1. Subject Content and Application Scope
This national standard specifies the maximum allowable emission limits of air pollutants for thermal power plants in periods. It's applicable to the emission management of existing thermal power plant as well as environmental impact assessment, design, final acceptance and post-construction emission management of the thermal power plant construction projects.
This national standard is applicable to the thermal power plants equipped with grate furnace (over 65t/h), coal-fired generation boiler excluding coal-throwing boiler, coal dust generation boiler, oil-fired generation boiler (over 65t/h) and compressor-turbine units. For the penetration boilers (65t/h) fired with biomass fuels like bagasse, sawdust and bark, the pollutant emission requirements shall be compliant to those of coal gangue-fired thermal power generation boilers.
This national standard is inapplicable to the thermal power plants fired with domestic wastes and hazardous wastes.
