To be published
1 Scope
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.
