NF EN ISO 13577-2, E32-203-2 (12/2023)

This document specifies safety requirements for combustion and fuel handling equipment that is part of industrial furnaces and associated equipment (TPE), including single and multiple burner systems in thermal equipment and machines. NOTE The general safety requirements common to VSEs are listed in ISO 13577-1:2016. ISO 13577-1:2016, Annex B also includes a list of processes for which industrial furnaces and heating systems covered by the ISO 13577 series are used. This document addresses significant hazards, hazardous situations and hazardous events that are relevant to combustion and fuel handling equipment, as listed in Annex A, when used normally and under operating conditions. use described in the instruction manual. This document covers: — fuel piping downstream of and including the manually operated check valve; — the combustion air supply (including oxygen and oxygen-enriched combustion air) and the combustion gas exhaust system; — the burner(s), the burner system(s) and the ignition device; — functional requirements for a safety-related control system. This document applies to any phenomenon of oxidation of gaseous and liquid fuels with air or other gases containing free oxygen so as to release heat in the TPE. Appendix B includes examples of gaseous and liquid fuels. With regard to thermal or catalytic post-combustion and waste incineration, this document applies only to auxiliary burners designed to start and/or support the process. The hazardous phenomenon caused by the pressure in the piping and components covered by this document corresponds to the maximum pressure/dimensions relationship of category I specified in Annex C. This document also gives the necessary requirements concerning the information for the use. This document does not cover hazards related to electrical heat. This document does not deal with dangerous phenomena caused by the release of flammable substances from products treated in the TPE. This document does not apply to combustion and fuel handling equipment: — for gas welding and related processes; — upstream of the TPE manually operated dam valve. This document does not apply to industrial furnaces and associated processing equipment (TPE), including single and multiple burner systems in heat processing equipment and machines manufactured before its publication date. This document is not applicable to blast furnaces, converters (of steel plants), boilers, heaters (including reforming furnaces) in the petrochemical and chemical industries. This document does not apply to electrical and power wiring upstream of the TPE control panel/protection system.
