Introduction
This document is primarily intended for forced draught oil burners having a combustion air fan,
operated with liquid fuels, and intended to be marketed as a complete assembly.
Forced draught oil burners according to this document are also used in industrial applications. The
safety principles are the same as for forced draught oil burners used for household/commercial
applications. Industrial forced draught 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 characterized by the ability to withstand industrial environmental
influences, like moisture, high temperature, electrical and magnetic phenomena, vibrations, etc.
Special requirements for forced draught burners for industrial premises are given in the form of notes
and identified by “industrial application”.
Further information and application limitations for forced draught burners, which are used for
industrial application, are given in informative Annex H.
Principal requirements for installation of oil burners for industrial thermal processing are covered by
EN 746-2.
This document is a type C standard as stated in EN ISO 12100.
The machinery concerned and the extent to 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 of the other
standard, for machines that have been designed and built according to the provisions of this type C
standard.
1 Scope
This document specifies the terminology, the general requirements for the construction and operation
of forced draught oil burners and also the provision of control and safety devices, and the test
procedure for these burners.
This document applies to forced draught oil burners supplied with:
— fuel based on first raffinates and their mixtures with biogenous liquid fuels having a viscosity at the
2 2
burner inlet of 1,6 mm /s (cSt) up to 6 mm /s (cSt) at 20 °C, and
— higher boiling petroleum based first raffinates (viscosity greater than 6 mm /s), that require
preheating for proper atomization.
This document is applicable to:
— single burners fitted to a single combustion chamber;
— single burners fitted to an appliance with additional requirements;
NOTE When additional requirements which are not identified or specified in this standard apply, the
specification of the required safety measures and/or protective devices and compliance with them is outside the
scope of this standard.
— single-fuel and dual-fuel burners when operating on oil only;
— the oil function of dual-fuel burners designed to operate simultaneously on liquid and gaseous
fuels, which, for the latter, the requirements of EN 676 also apply.
This document 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, see Annex J.
This document also deals with the additional requirements for the burners in the scope with
pressurized parts and/or firing pressurized bodies, see Annex K.
This document specifies the requirements to ensure the safety during commissioning, start-up,
operation, shut-down and maintenance.
This document deals also with forced draught burners intended to be used with biogenous liquid fuels,
mixtures.
This document deals also with burners and their equipment to increase the total appliance efficiency,
see Annex M.
