EN 267:2020

Forced draught burners for liquid fuels

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 and their equipment to increase the total appliance efficiency, see Annex M.

400 kW;
— update of definitions;
— electrical interfaces for burners;
— modification:
— test and working diagram NO emission calculation;
X
— replacement of EN 50156-1:2004 by EN 60204-1 to include international available
requirements for the electrical safety of machines; see Annex L with editorial allocation in
Annex K;
— Annex J is adapted to the new ISO EN 12100 which is substituting EN 1050 which is currently
referenced to in Table J.1;
— mass flow rate is changed into heat input;
— new functions / requirements:
— remote reset;
— environmental aspects (environmental check list);
— increase of burner efficiency;
— terminology for burner load control;
— NO mean value for evaluating the NO classes;
X X
— implementing new requirements to comply with the 2013/813 (ErP);
— requiring of a risk assessment as required by EU directive 2014/35/EU for LVD and EU
Directive 2014/30/EU for EMC.
