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 applies to single wall chimneys regarding their contact with flue gases.
For simplicity, these various designs will generally be referred to herein as "liners".
The mechanical requirement is not part of this document, for information see prEN 1993 3.
NOTE   Liners built from prefabricated metal chimneys in accordance with EN 1856 1:2009 and
EN 1856 2:2009 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, die mit den Abgasen in Berührung kommen.
Der Einfachheit halber werden verschiedene Bemessungen hier grundsätzlich als "Innenrohre" bezeichnet.
Die mechanischen Anforderungen sind nicht Teil dieses Dokuments. Für Informationen siehe prEN 1993 3.
ANMERKUNG   Innenrohre aus vorgefertigten Metallschornsteinen nach EN 1856 1:2009 und EN 1856 2:2009 werden als unten abgestützte Innenrohre mit zusätzlichen Abstützungen und Führungen, wie in diesem Dokument definiert, eingebaut.
