Free-standing chimneys - Part 4: Brick liners - Design and execution

This European Standard specifies special requirements and performance criteria for the design and construction of lining systems made of brickwork for free-standing industrial chimneys. Current European practice favours sectional liners and the statements of the standard are mainly devoted to such solutions but are also largely applicable to base supported independent and stayed liners. The differences in the design and construction of the two last types are covered by Annex A. This European Standard identifies requirements to ensure mechanical resistance and stability of liners in accordance with the general requirements given in EN 13084-1.
Lining systems comprise some or all of the following:
chimney liner including duct entry;
insulation;
liner support;
space between liner and concrete windshield.
Gas flow calculations to determine liner sizes are covered by EN 13084-1.

Freistehende Schornsteine - Teil 4: Innenrohre aus Mauerwerk - Entwurf, Bemessung und Ausführung

Diese Europäische Norm behandelt die besonderen Anforderungen und die Leistungskriterien für Entwurf, Bemessung und Ausführung von Innenrohrkonstruktionen aus Mauerwerk für freistehende Industrieschornsteine. In der gängigen europäischen Praxis werden aus einzelnen Abschnitten bestehende Innenrohre (Etagen-Innenrohre) bevorzugt, und die Festlegungen der Norm beziehen sich hauptsächlich auf diese Lösungen, gelten aber auch weitestgehend für unten abgestützte freistehende und horizontal abgestützte Innenrohre. Diese Europäische Norm beschreibt die Anforderungen an die mechanische Festigkeit und Stabilität von Innenrohren entsprechend den allgemeinen Anforderungen nach EN 13084-1.
Innenrohrkonstruktionen bestehen vollständig oder teilweise aus folgenden Teilen:
-   Schornsteininnenrohr einschließlich Abgaskanal-Einführung;
-   Wärmedämmung;
-   Innenrohrabstützung;
-   Raum zwischen Innenrohr und Beton-Tragrohr.
Strömungstechnische Berechnungen zur Bestimmung der Innenrohrmaße sind in EN 13084-1 angegeben.

Cheminées indépendantes - Partie 4: Parois intérieurs en terre cuite - Planification et exécution

La présente Norme européenne spécifie les exigences et critères de performance particuliers applicables à la conception et à la construction des systèmes de conduit intérieur en briques de terre cuite pour les cheminées industrielles autoportantes. La pratique courante en Europe favorise les conduits en sections ; les exigences de la présente norme concernent principalement ces solutions, mais elles sont aussi largement applicables aux conduits portés par la base indépendants et étayés. La présente Norme européenne définit les exigences permettant de garantir la résistance mécanique et la stabilité des conduits intérieurs, conformément aux exigences générales données dans l'EN 13084-1.
Les systèmes de conduit intérieur sont constitués de tout ou partie des éléments suivants :
-   le conduit intérieur de cheminée avec une arrivée de gaine ;
-   l'isolation ;
-   le support du conduit intérieur ;
-   l'espace entre le conduit intérieur et le brise-vent en béton.
Les calculs de débit de gaz visant à déterminer la taille des conduits intérieurs sont expliqués dans l'EN 13084-1.
