This European Standard 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 European Standard 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 burner inlet of 1,6 mm2/s (cSt) up to 6 mm2/s (cSt) at 20 °C; and
― higher boiling petroleum based first raffinates (viscosity greater than 6 mm2/s), that require preheating for proper atomization.
This European Standard is applicable to:
― single burners fitted to a single combustion chamber;
― single burners fitted to an appliance with additional requirements;
NOTE When additional requirements apply which are not identified or specified in this standard, 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 gaseous and liquid fuels.
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, see Annex J.
This European Standard also deals with the additional requirements for the burners in the scope with pressurized parts and/or firing pressurized bodies, see Annex K.
This European Standard specifies the requirements to ensure the safety during commissioning, start-up, operation, shut-down and maintenance.
This European Standard deals also with forced draught burners intended to be used with biogenous liquid fuels, mixtures.
This European Standard deals also with burners equipment to increase the total appliance efficiency; see Annex M.

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.

This draft European Standard is submitted to CEN members for unique acceptance procedure. It has been drawn up by the

Technical Committee CEN/TC 47.

If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations

which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other

language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC

Management Centre has the same status as the official versions.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,

Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,

Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and

United Kingdom.

Recipients of this draft are invited to submit, with their comments, notification of any relevant patent rights of which they are

aware and to provide supporting documentation.
