DB37/ 2375-2019 in English

ChinaStandards.net 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 developed in accordance with the rules given in GB/T 1.1-2009.

This standard replaces DB 37/ 2375-2013 Emission standard of air pollutants for industrial furnace and kiln in Shandong Province, and the following main technical changes have been made with respect to DB 37/ 2375-2013:

——the pollutant control factors are adjusted;

——the emission limits for some pollutants are tightened;

——the emission limit for chromium and its compounds is added;

——the benchmark oxygen content of some industrial furnaces and kilns is adjusted;

——the criteria for compliance are defined.

During the transition period before the implementation of this standard, the characteristic air pollutants emitted by existing industrial furnaces and kilns shall comply with the relevant requirements of DB 37/ 2375-2013 Emission standard of air pollutants for industrial furnace and kiln in Shandong Province; the particulate matters, sulfur dioxide and nitrogen oxides emitted by the industrial furnaces and kilns shall comply with the relevant requirements of DB37/ 2376.

This standard was proposed by the Department of Ecology and Environment of Shandong Province.

This standard is under the jurisdiction of the Technical Committee for Standardization of Environmental Protection of Shandong Province.

This standard was firstly issued in 2013 and is revised for the first time.

Emission standard of air pollutants for industrial furnace and kiln

1 Scope

This standard specifies the emission limits, monitoring and control requirements for characteristic air pollutants from industrial furnaces and kilns in Shandong Province, and the implementation and supervision of the standard.

This standard is applicable to the emission control of characteristic air pollutants from existing industrial furnaces and kilns in Shandong Province, and to the environmental impact assessment, environmental protection facility design and acceptance and pollutant discharge permit for the construction projects of industrial furnaces and kilns, as well as the emission control of air pollutants after such industrial furnaces and kilns are put into operation.

This standard is not applicable to furnaces and kilns in iron and steel industry, building materials industry, hazardous waste incineration and other industries in Shandong Province, and their emissions of air pollutants shall comply with the national or corresponding professional standards for emission of air pollutants in Shandong Province.
