Emission standard of air pollutants for boilers
1 Application scope
This standard specifies the emission control requirements, monitoring, and implementation and supervision of standard of air pollutants for boilers.
This standard is applicable to the management of emission of air pollutants for boilers, as well as the environmental impact assessment, the design of environmental protection facilities, the environmental protection completion acceptance, the issuance of pollutant emission permits and the management of the emission of air pollutants after putting into operation of the constructed, renovated and expanded projects.
This standard is applicable to steam boilers, hot water boilers and organic heat carrier boilers with output of single set less than 65t/h. The boilers using alcohol ether fuels (such as methanol, ethanol, dimethyl ether, etc.) shall be implemented by reference to the gaseous fuel boilers in this standard.
This standard is not applicable to boilers fueled by household wastes, hazardous wastes and other non-hazardous wastes.
This standard is applicable to the legal pollutant emission behaviors. The site selection of the newly-set pollution source and the management of the current pollution source in special protected areas shall be conducted in accordance with the relevant provisions specified in such laws, regulations and rules as Law of the People's Republic of China on the Prevention and Control of Atmospheric Pollution, Law of the People's Republic of China on Evaluation of Environmental Effects, Regulations of Shanghai Municipality on Environmental Protection, and Regulations of Shanghai Municipality on Prevention and Control of Air Pollution.
