In order to implement the Environmental Protection Law of the PEOPLE Republic of China, to implement this Standards of national and local air pollutants emissions, to implement the total control of atmospheric emissions of pollutants from stationary sources, to improve the level of continuous emission monitoring of flue gas from stationary sources, this Standard is formulated.
This Standard specifies the technical requirements of continuous emission monitoring systems of flue gas from stationary sources (HJ/T 75-2001) - installation, debugging, networking, inspection, operation, maintenance and data auditing.
This Standard make the following main modifications for Technical Specifications of Continuous Emission Monitoring of Thermal Power Plant (HJ/T75-2001). expand the scope of the original specification, cover the industrial stationary sources; refine the requirements of the installation location of continuous emission monitoring systems of flue gas from stationary sources and audits and processing requirements of data which have been accepted and transferred to the automatic pollution monitoring network; provide operational management and quality assurance requirements for continuous emission monitoring system of flue gas from stationary sources; simplify various monitoring methods of continuous emission of flue gas from stationary sources; supplement the testing and comparison methods of continuous emission monitoring system of flue gas from stationary sources, technical requirements and related record forms.
This Standard is a guidance standard.
This Standard is put forward by Department of Science, Technology and Standards of State Environmental Protection Administration.
This Standard was drafted by Shanghai Environmental Monitoring Center, China National Environmental Monitoring Center, China-Japan Friendship Center for Environmental Protection.
This Standard was approved by the State Environmental Protection Administration on July 12, 2007.
This Standard has been implemented from August 1, 2007 and replaced the Technical Specifications of Continuous Emission Monitoring of Thermal Power Plant (HJ/T75- 2001)
This Standard shall be explained by State Environmental Protection Administration. Specifications for Continuous Emissions Monitoring of Flue Gas Emitted from Stationary Sources (on Trial)
1 Applicable Scope
1.1 This Standard specifies the main technical targets, test items, installation location, commissioning testing methods, inspection methods, the daily operation and management, daily operation of quality assurance, data auditing and reporting format of the data of the particulate matter CEMS, gaseous pollutants (including SO2, NO, etc.) CEMS and related exhaust parameters (oxygen, etc.) of Continuous Emissions Monitoring Systems, CEMS.
1.2 This Standard is applicable to solid, liquid fuel or raw material for the thermal power plant boilers, industrial / commercial boilers and industrial furnaces and other stationary sources of CEMS.
1.3 Garbage incinerators, hazardous waste incinerators and gases which use fuel or raw CEMS stationary sources shall refer to this Standard.
