Defines the safety requirements for combustion and fuel handling systems that are part of industrial furnaces and associated processing equipment (TPE).

This part of ISO13577 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 ISO13577-1 (See introduction).

This part of ISO13577 deals with significant hazards, hazardous situations and events relevant to combustion and fuel handling systems as listed in AnnexA, when used as intended and under the conditions foreseen by the manufacturer.

This part of ISO13577 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 ISO13577 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 ISO13577 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 ISO13577 is within the maximum pressure/size relationship of categoryI as described in normative AnnexE.

This part of ISO13577 also gives the necessary requirements regarding information for use.

This part of ISO13577 does not cover hazards from heating generated by electricity.

This part of ISO13577 does not deal with the hazards created by the release of flammable substances from the products processed in the TPE.

This part of ISO13577 is not applicable to combustion and fuel handling systems:

• of welding machines;

• up-stream of the TPE manual isolating valve.

This part of ISO13577 is not applicable to electrical cabling and power cabling upstream of the TPE control panel/protective system.
