Heating boilers - Heating boilers with forced draught burners - Nominal heat output not exceeding 10 MW and maximum operating temperature of 110 °C
This European Standard specifies the requirements and test methods for the design, manufacturing, safe operation and the rational energy usage for standard boilers and low temperature boilers (with "boiler" in the sense of "boiler body") from steel and cast iron to be equipped with separately marketed forced draught burners according to the relevant burner standards (for automatic forced draught burners for gaseous fuels see EN 676 and for atomising oil burners see EN 267) up to a nominal heat output of 10 MW. They are operated, either with negative pressure (natural draught boiler) or with positive pressure (pressurised boiler) in the combustion chamber, in accordance with the boiler manufacturer's instructions."
This European Standard specifies requirements for boilers with normal operating temperatures between 100 °C and 110 °C and has a "dual structure":
- For boilers where the shut off temperature of the safety temperature limiter does not exceed 110 °C the Pressure Equipment Directive (PED) requires" Sound Engineering Practice",
- For boilers where the shut off temperature of the safety temperature limiter exceeds 110 °C this European Standard specifies the requirements of the PED as stated in Annex ZB.
NOTE 1 The "maximum allowable temperature TS" is defined in the PED and its Guidelines."
Boilers in accordance with this European Standard are designed for the heating of central heating installations in which the heat carrier is water, and the maximum allowable operating temperature of which is up to 110 C and the maximum safety temperature limiter of 120 C. The maximum allowable operating pressure is 10 bar.
This standard does not apply to gas boilers with atmospheric burners, boilers for solid fuels, oil or gas fired condensation boilers, boilers with oil vaporisation burners. For these boilers there are further requirements.
For gas-fired central heating boilers equipped with a forced draught burner of nominal heat out put not exceeding 1000 kW,
Heizkessel - Heizkessel mit Gebläsebrennern - Nennwärmeleistung kleiner oder gleich 10 MW und einer maximalen Betriebstemperatur von 110 °C
Diese Europäische Norm legt die Anforderungen und Prüfverfahren für den Aufbau, die Fertigung, die sichere Bedienung und den rationellen Energieverbrauch für Standardheiz- und Niedertemperaturkessel (wobei 'Heiz¬kessel' im Sinne von 'Heizkessel-Körper' verstanden wird) aus Stahl und Gusseisen fest, die mit separat erhältlichen Gebläsebrennern nach den entsprechenden Normen für Brenner (für automatische Brenner mit Gebläse für gasförmige Brennstoffe siehe EN 676 und für Ölzerstäubungsbrenner siehe EN 267) bis zu einer Nennwärme-Leistung von 10 MW ausgestattet sind. Sie sind nach den Anweisungen des Kesselherstellers entweder mit Unterdruck (Naturzugkessel) oder mit Überdruck (Überdruckkessel) im Brennraum zu betreiben.
Diese Europäische Norm legt die Anforderungen für Heizkessel mit normalen Betriebstemperaturen zwischen 100 °C und 110 °C fest und weist eine 'duale Struktur' auf:
für Heizkessel, bei denen die Abschalt-Temperatur des Sicherheitstemperaturbegrenzers 110 °C nicht überschreitet, fordert die Druckgeräte-Richtlinie (PED) gute Ingenieurpraxis;
für Heizkessel, bei denen die Abschalt-Temperatur des Sicherheitstemperaturbegrenzers mehr als 110 °C beträgt, legt diese Europäische Norm die Anforderungen nach der PED fest, wie in Anhang ZB angegeben.
ANMERKUNG 1 Die maximal zulässige Temperatur TS ist in der PED und deren Leitlinien definiert."
Heizkessel nach dieser Europäische Norm sind bestimmt für die Beheizung von zentralen Heizungsanlagen, deren Wärmeträger Wasser mit einer maximalen Betriebstemperatur bis 110 °C und einer Absicherungstemperatur von 120 °C ist. Der hydrostatische Betriebsüberdruck beträgt maximal 10 bar.
Diese Norm gilt nicht für Gasspezialheizkessel mit atmosphärischen Brennern, Heizkessel für feste Brennstoffe, öl- bzw. gasbefeuerte Brennwertkessel, Heizkessel mit Ölverdampfungsbrennern. Für diese Kessel sind andere und teilweise zusätzliche Anforderungen zu erfüllen.
Chaudières de chauffage - Chaudières avec brûleurs à air soufflé - Puissance utile inférieure ou égale à 10 MV et température maximale de service de 110 °C
La présente Norme européenne spécifie les exigences et les méthodes d’essai pour la conception, la fabrication, la sécurité et l’utilisation rationnelle de l’énergie pour des chaudières standard et des chaudières à basse température («chaudière» au sens de «corps de chaudière») en acier et en fonte, devant être équipées de brûleurs à air soufflé commercialisés séparément, conformes aux normes applicables aux brûleurs (pour les brûleurs automatiques à air soufflé pour combustibles gazeux, voir l’EN 676 et pour les brûleurs à fioul à pulvérisation, voir l’EN 267) jusqu’à une puissance utile nominale de 10 MW. Ces chaudières fonctionnent, selon les instructions du fabricant, soit en dépression (à tirage naturel), soit en pression (chaudières pressurisées) dans la chambre de combustion."
!La présente Norme européenne spécifie les exigences relatives aux chaudières dont la température normale de service est comprise entre 100 °C et 110 °C ; elle est structurée en «deux volets» :
Pour les chaudières dont la température de coupure du thermostat limiteur de sécurité ne dépasse pas 110 °C, la directive relative aux équipements sous pression (DEP) exige l’application des «règles de l’art en usage»,
Pour les chaudières dont la température de coupure du thermostat limiteur de sécurité est supérieure à 110 °C, la présente Norme européenne spécifie les exigences de la DEP indiquées dans l’Annexe ZB.
NOTE 1 La «température maximale autorisée TS» est définie dans la DEP et ses Lignes directrices."
Les chaudières conformes à la présente norme sont conçues pour des installations de chauffage central dont le fluide caloporteur est l'eau, et la température maximale de service autorisée est inférieure ou égale à 110 °C et la température maximale du thermostat limiteur de sécurité est de 120 °C. La pression maximale de service autorisée est de 10 bars.
