Codeofchina.com is in charge of this English translation. In case of any doubt about the English translation, the Chinese original shall be considered authoritative. This standard is formulated with a view to implementing Environmental Protection Law of the People's Republic of China, Law of the People's Republic of China on the Prevention and Control of Atmospheric Pollution and Regulations of Shanghai Municipality on Environmental Protection, strengthening the emission control of air pollutants for boilers, promoting the technological progress and sustainable development of the industry, improving the environmental quality and protecting human health in combination with the actual situation of Shanghai Municipality. This standard specifies the emission limits, monitoring and supervising requirements for air pollutants for boilers. This standard was issued in 2007 as first edition, its first revision was issued in 2014, and this is the second revision. The following main changes have been made with respect to DB31/387-2014: ——the classification of boilers in emission limits is adjusted; ——the requirements for pollutant emission control are improved. This standard serves as the basic requirements for the emission control of air pollutants for boiler. In case the requirements of environmental impact assessment documents or pollutant emission permits are stricter than this standard, the approved environmental impact assessment documents or issued pollutant emission permits shall prevail. This standard was revised by Shanghai Municipal Environmental Protection Bureau. This standard was approved by Shanghai Municipal People's Government on May 21, 2018. This standard was implemented from June 7, 2018. Shanghai Municipal Environmental Protection Bureau is in charge of the explanation of this standard. 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. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this standard.
