Resumen:
This European Standard specifies the terminology, the general requirements for the construction and operation of automatic forced draught gas burners and also the provision of control and safety devices, and the test procedure for these burners. This standard is applicable to - automatic gas burners with a combustion air fan (hereinafter called "burners") as described in 3.1.2 and gas line components, intended for use in appliances of different types, and that are operated with gaseous fuels; - total pre mixed burners and nozzle mixed burners. The standard is applicable to - single burners with a single combustion chamber; - single fuel and dual fuel burners when operating only on gas; - the gas function of dual-fuel burners designed to operate simultaneously on gaseous and liquid fuels, which, for the latter, the requirements of EN 267 also apply. 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 Standard specifies the requirements to be met by the manufacturer to ensure the safety during commissioning, start-up, operation, shut-down and maintenance. This European Standard does not deal with hazards due to specific applications. It is not applicable to automatic forced draught gas burners which are manufactured before the date of its publication as EN. This European Standard does not apply to burners specifically designed for use in industrial processes carried out on industrial premises. This European Standard deals also with the additional requirements for the burners in the scope with pressurised parts and /or firing pressurised bodies, see Annex K. It deals also with forced draught burners intended to be used with biogenous gaseous fuels, mixtures with line conveyed gas and special gaseous fuels.
