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 EN 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.
