This part of EN 746 together with EN 746-1 specifies safety requirements for single and multiple burners that are part of Industrial Thermoprocessing Equipment. (In this standard referred to as IThE).
This document deals with significant hazards, hazardous situations and events relevant to combustion and fuel handling systems that are part of IThE as listed in Clause 4, when used as intended and under the conditions foreseen by the manufacturer.
This European Standard covers:
- fuel pipework downstream of and including the manual isolating valve;
- burner(s), burner system and ignition device;
- safety related control system (protective system).
This European Standard applies to any oxidation with air or other gases containing free oxygen of gaseous, liquid and solid fuels or any combustion of them to release thermal energy.
For thermal or catalytic post combustion and waste incineration, this European Standard 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 standard is within the maximum pressure/size relationship of category I as described in normative Annex D.
This European Standard also gives the necessary requirements for the information for use.
This European Standard does not cover hazards from heating generated by electricity.
This European Standard does not deal with the hazards created by the release of flammable substances from the products processed in the IThE.
NOTE EN 1539, Dryers and ovens, in which flammable substances are released — Safety requirements
This European Standard is not applicable to combustion and fuel handling systems
- of welding and soldering machines;
- up-stream of the IThE manual isolating valve.
This European Standard is not applicable to electricity cabling and power cabling upstream of the IThE control panel/protective system.
Noise can be a significant hazard for combustion and fuel handling systems.
