Shell boilers - Part 7 : Requirements for firing systems for liquid and gaseous fuels for the boilers

These requirements apply to oil and gas firing systems of steam and hot water generators. For multifuel firing systems using separate or combined burners these requirements shall apply to the oil and/or gas firing part involved. Where several fuels are burnt simultaneously, improved safety measures may be necessary, especially in respect to limitation of heat input into the firing system and proper air supply to the individual fuels.

Großwasserraumkessel - Teil 7 : Anforderungen an Feuerungsanlagen für flüssige und gasförmige Brennstoffe für den Kessel

Diese Anforderungen gelten für Öl- und Gasfeuerungsanlagen an Dampf- und Heißwasserzeugern. Für kombinierte Feuerungsanlagen mit getrennten oder kombinierten Brennern gelten diese Anforderungen für den Öl- und/oder Gasfeuerungsteil. Wenn verschiedene Brennstoffe gleichzeitig verbrannt werden, können erhöhte Sicherheitsmaßnahmen nötig werden, vorzugsweise im Hinblick auf die Begrenzung der Wärmeleistung der Feuerungsanlage und richtige Lufzuführung zu den einzelnen Brennstoffen.

Chaudières à tubes de fumée - Partie 7 : Exigences pour les équipements de chauffe pour combustibles gazeux et liquides de la chaudière

La présente Norme européenne spécifie les exigences applicables aux équipements de chauffe pour fioul et combustibles gazeux des chaudières à tubes de fumée indépendamment de leur niveau de surveillance. En ce qui concerne les équipements de chauffe polycombustibles utilisant des brûleurs séparés ou combinés, ces prescriptions s'appliquent à l'élément de chauffe pour fioul et/ou gaz impliqué.
Lorsque plusieurs combustibles sont brûlés simultanément, des mesures de sécurité améliorées peuvent être requises, en particulier pour ce qui concerne la limitation de l'apport calorifique à l'équipement de chauffe et l'alimentation en air appropriée pour chaque combustible.
Pour les équipements de chauffe à fioul et gaz les prescriptions de l'EN 267 ou l'EN 676 s'appliquent.
