HJ 462-2021 (English Version) PDF

Scope: This standard specifies the pollutants and pollution load, overall requirements, process design, main process equipment and materials, testing and process control, main auxiliary projects, labor safety and occupational health, construction and acceptance, operation and Maintenance etc. The industrial boilers mentioned in this standard refer to steam boilers with a single boiler output of coal as fuel between 10 t/h and 65 t/h (inclusive), hot water boilers with a capacity greater than 7 MW, and organic heat carrier boilers. and layer-fired boilers. This standard applies to the treatment projects of three types of pollutants: particulate matter, sulfur dioxide (SO2) and nitrogen oxides (NOx) in industrial boiler flue gas. For other pollutants such as mercury in industrial boiler flue gas, priority should be given to flue gas treatment projects. Governing through synergy. This standard can be used as the technical basis for environmental impact assessment, engineering design, construction, commissioning, acceptance, operation management and environmental supervision of industrial boiler flue gas treatment projects. The control projects for particulate matter, sulfur dioxide and nitrogen oxides in the flue gas of boilers and kilns using oil, gas and other fuels can be implemented by reference. This standard does not apply to boiler flue gas treatment projects that use hazardous waste as fuel or are mixed with hazardous waste.
