BS EN 267:2009+A1:2011EN 267:2009+A1:2011 (E) 5 Introduction This European Standard is primarily intended for automatic forced draught oil burners having a combustion air fan, operated with liquid fue

33、ls, and intended to be marketed as a complete assembly. Forced draught oil burners according to this European Standard are often used in industrial applications. The safety principles are the same as for forced draught oil burners used for household/commercial applications. Industrial forced draught

34、 oil burners however need to operate safely in their industrial environment and the risks involved can differ from those for household applications. These industrial forced draught oil burners can be characterised by the ability to withstand industrial environmental influences, like moisture, high t

35、emperature, electrical and magnetic phenomena, vibrations, etc. Special requirements for forced draught burners for industrial premises will be given as a note with the addition “Industrial application“. Further information and application limitations for forced draught burners, which are used for i

36、ndustrial application, are given in informative Annex H. Principal requirements for installation of oil burners for industrial thermal processing are covered by EN 746-1 to -8. This document is a type C standard as stated in EN ISO 12100-1 and EN ISO 12100-2. The machinery concerned and the extent t

37、o which hazards, hazardous situations and hazardous events are covered are indicated in the scope of this document. When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions o

38、f the other standard, for machines that have been designed and built according to the provisions of this type C standard. BS EN 267:2009+A1:2011EN 267:2009+A1:2011 (E) 6 1 Scope This European Standard specifies the terminology, the general requirements for the construction and operation of automatic

39、 forced draught oil burners and also the provision of control and safety devices, and the test procedure for these burners. This European Standard applies to automatic forced draught oil burners supplied with: a fuel having a viscosity at the burner inlet of 1,6 mm/s (cSt) up to 6 mm/s (cSt) at 20 C

40、; and higher boiling petroleum based first raffinates (viscosity greater than 6 mm2/s), that require preheating for proper atomisation. This European Standard is applicable to: single burners fitted to a single combustion chamber; single burners fitted to an appliance with additional requirements, t

41、hen the relevant standard of this appliance shall be taken into account; single-fuel and dual-fuel burners when operating on oil only; the oil function of dual-fuel burners designed to operate simultaneously on gaseous and liquid fuels, in which case the requirements of EN 676 will also apply in res

42、pect of the gaseous fuel function. This European Standard deals with all significant machine hazards, hazardous situations and events relevant to burners, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer, see Annex J. This European St

43、andard also deals with the additional requirements for the burners in the scope with pressurised parts and/or firing pressurised bodies, see Annex K. This European Standard specifies the requirements to be met by the manufacturer to ensure the safety during commissioning, start-up, operation, shut-d

44、own and maintenance. This European Standard does not deal with hazards due to specific applications. This European Standard is not applicable to automatic forced draught oil burners which are manufactured before the date of its publication as European Standard. 2 Normative references The following r
