Področje projekta (angleško): This part of EN 746 specifies the safety requirements for combustion and fuel handling systems that are part of industrial furnaces and associated processing equipment (TPE). NOTE The general safety requirements common to TPE are provided in prEN 746 1:2020 (See introduction). This part of EN 746 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 foreseen by the manufacturer. This part of EN 746 covers: - fuel pipework downstream of and including the manual isolating valve; - combustion air supply (including oxygen and oxygen enriched combustion air) and flue gas system; - burner(s), burner system and ignition device; - functional requirements for safety related control system. This part of EN 746 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. For thermal or catalytic post combustion and waste incineration, this part of EN 746 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 EN 746 is within the maximum pressure/size relationship of category I as described in normative Annex E. This part of EN 746 also gives the necessary requirements regarding information for use. This part of EN 746 does not cover hazards from heating generated by electricity. This part of EN 746 does not deal with the hazards created by the release of flammable substances from the products processed in the TPE. This part of EN 746 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 EN 746 is not applicable to electrical cabling and power cabling upstream of the TPE control panel/protective system.
