The work of preparing International Standards is norma
12、lly carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in th
13、e work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the
14、different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this documen
15、t may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/p

19、tionThis document is a type-C standard as defined in ISO 12100.The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are covered, is indicated in the Scope of this document.When requirements of this type-C standard are different from those which are stated
20、 in type-A or -B standards, the requirements of this type-C standard take precedence over the requirements of the other standards, for machines that have been designed and built according to the requirements of this type-C standard.This part of ISO 13577 assumes that the equipment is not creating an
21、y potentially explosive atmosphere and is located in a normally ventilated area.Compliance with product standards e.g. ISO 22967 or ISO 22968 is not sufficient to ensure the minimum safety requirements for industrial furnaces and associated processing equipment (TPE). This part of ISO 13577 shall al
22、ways have priority for TPE.Industrial furnaces and associated processing equipment (TPE) generally consists of the following components: processing chamber (e.g. steel construction with lining and/or refractory); heating systems; protective system; control and instrumentation system / operator-contr
23、ol level.ISO 13577-1 provides the general safety requirements common to TPE. This part of ISO 13577 details in addition specific safety requirements for combustion and fuel handling systems that are part of TPE as listed in the Scope.NOTE As stated in its scope, ISO 13577-1 does not cover blast furn
24、aces, converters (in steel plants), boilers and equipment not covered by ISO 12100.The requirements for protective systems are specified in ISO 13577-4.If a general requirement of ISO 13577-1 counters requirements in this part of ISO 13577, the requirements of this part of ISO 13577 take precedence.
25、The requirements for reducing hazards from noise are given in ISO 13577-1.It is assumed that TPE will only be operated and maintained by trained personnel.

26、stion and fuel handling systems1 ScopeThis 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).NOTE The general safety requirements common to TPE are provided in ISO 13577-1 (See i
27、ntroduction).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 foreseen by the manufacturer.This part of ISO 13577 covers: fuel pipework downstre
28、am 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 ISO 13577 applies to any oxidation wit
29、h 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 ISO 13577 applies only to auxiliary burners designed to start-up and/or support the process
30、.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 described in normative Annex E.This part of ISO 13577 also gives the necessary requirements regarding information for use.This part of ISO 13577 does
31、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 welding machines; u
32、p-stream of the TPE manual isolating valve.This part of ISO 13577 is not applicable to electrical cabling and power cabling upstream of the TPE control panel/protective system.INTERNATIONAL STANDARD ISO 13577-2:2014(E) ISO 2014 All rights reserved 1BS ISO 13577-2:2014ISO 13577-2:2014(E)2 Normative r

In particular, all the components of the fuel pipework shall be capable of withstanding the mechanical, chemical and thermal loads to
45、 which they can be subjected during normal operation and foreseeable abnormal operation (e.g. identified during a safety assessment); reliable and correct time for ignition of the air/fuel-mixture at the burner(s); prevention of unintentional release of unburned fuels; shut-off fuel-supply in case o
46、f relevant fault; protection of pipeline to preclude the propagation of flame in reverse direction; prevent firing when the evacuation of flue gas/combustion products is not ensured; prevent firing when the process conditions are not in the safe state.Electrical circuits shall be designed in accorda
47、nce with IEC 60204-1.A risk assessment according to ISO 12100 shall be carried out.
