ÖNORM EN ISO 13577-2

This part of ISO 13577 specifies the safety requirements for combustion and fuel handling systems that are part of industrial furnaces and associated processing equipment (TPE), including single and multiple burner systems in thermoprocessing equipment and machines. This part of ISO 13577 deals with significant hazards, hazardous situations and events relevant to combustion and fuel handling systems as listed in Annex A, when used as intended and under the conditions for use as described in the instruction handbook. This part of ISO 13577 applies to any oxidation with air or other gases containing free oxygen of gaseous and liquid fuels or any combustion of them to release thermal energy in TPE. Annex B includes examples of gaseous and liquid fuels. For thermal or catalytic post combustion and waste incineration, this part of ISO 13577 applies only to auxiliary burners designed to start-up and/or support the process. The pressure hazard of the piping and components covered by this part of ISO 13577 is within the maximum pressure/size relationship of category I as specified in Annex C. This part of ISO 13577 also gives the necessary requirements regarding information for use. This part of ISO 13577 does not cover hazards from heating generated by electricity. This part of ISO 13577 does not deal with the hazards created by the release of flammable substances from the products processed in the TPE. This part of ISO 13577 is not applicable to combustion and fuel handling systems: - of gas welding and allied processes; - up-stream of the TPE manual isolating valve. This part of ISO 13577 is not applicable to blast furnaces, converters (in steel plants), boilers, fired heaters (including reformer furnaces) in the petrochemical and chemical industries. This part of ISO 13577 is not applicable to electrical cabling and power cabling upstream of the TPE control panel/protective system. This document is not applicable to combustion and fuel handling systems manufactured before the date of its publication.
