Free-standing chimneys - Part 6: Steel liners - Design and execution

This document deals with special requirements and performance criteria for the design of lining systems made of steel for free standing chimneys. It specifies the requirements for cylindrical steel liners as stated in EN 13084 1.
This document covers the design of the following three basic types of liners located in a load bearing structure:
a)   base supported liner;
b)   sectional liner;
c)   top hung liner.
Additionally this document also applies to single wall chimneys whose surface is in contact with flue gases.
Liners built from prefabricated metal chimneys in accordance with EN 1856-1 and EN 1856-2 are installed as base supported liners with additional supports and guides as defined in this document.

Freistehende Schornsteine - Teil 6: Innenrohre aus Stahl - Bemessung und Ausführung

Dieses Dokument befasst sich mit den besonderen Anforderungen und Ausführungskriterien für das Bemessen und Konstruieren von Innenrohrkonstruktionen aus Stahl bei freistehenden Schornsteinen. Es legt die Anforderungen an zylindrische Innenrohre aus Stahl, wie in EN 13084-1 angegeben, fest.
Dieses Dokument gilt für das Bemessen und Konstruieren folgender drei Grundtypen von Innenrohren, die sich in einer tragenden Konstruktion befinden:
a)   unten abgestütztes Innenrohr;
b)   Etageninnenrohr;
c)   hängendes Innenrohr.
Das vorliegende Dokument gilt zusätzlich für einwandige Schornsteine, deren Oberfläche mit den Abgasen in Berührung kommt.
Innenrohre aus vorgefertigten Metallschornsteinen nach EN 1856 1 und EN 1856 2 werden als unten abgestützte Innenrohre mit zusätzlichen Abstützungen und Führungen, wie in diesem Dokument definiert, eingebaut.

Cheminées autoportantes - Partie 6: Parois intérieures en acier - Conception et mise en oeuvre

Le présent document traite des exigences spécifiques et des critères de performance concernant la conception de systèmes de parois intérieures en acier destinés aux cheminées autoportantes. Il spécifie les exigences relatives aux parois intérieures cylindriques en acier données dans l’EN 13084-1.
Ce document couvre la conception des trois types de paroi de base qui se trouvent dans la structure porteuse :
a)   paroi intérieure soutenue à la base ;
b)   paroi intérieure en tronçons ;
c)   paroi intérieure suspendue par le haut.
De plus, ce document s’applique également aux cheminées à paroi simple dont la surface est en contact avec les fumées.
Les parois réalisées à partir de conduits métalliques préfabriqués conformément à l’EN 1856-1 et l’EN 1856-2 sont installées comme parois intérieures soutenues à la base avec des supports et guides supplémentaires tels que définis dans le présent document.

Prostostoječi dimniki - 6. del: Jeklene tuljave - Projektiranje in izvedba

Ta dokument opisuje posebne zahteve in merila učinkovitosti za načrtovanje tuljavnih sistemov iz jekla za prostostoječe dimnike. Določa zahteve za cilindrične jeklene tuljave, kot je navedeno v standardu EN 13084 1.
Ta dokument zajema načrtovanje treh osnovnih vrst tuljav, nameščenih v nosilnih strukturah:
a) tuljave s podprtim podnožjem;
b) sestavljive tuljave;
c) vrhnje pritrjene tuljave.
Poleg tega se ta dokument uporablja tudi za enojne dimnike, katerih površina je v stiku z dimnimi plini.
Tuljave, sestavljene iz vnaprej izdelanih kovinskih dimnikov v skladu s standardom EN 1856-1 in EN 1856-2, so nameščene kot tuljave s podprtim podnožjem z dodatnimi oporniki in vodili, kot je opredeljeno v tem dokumentu.
