DINEN 13084-6:2016-02EN 13084-6:2015 (E) 4 1 Scope This document deals with special requirements and performance criteria for the design of lining systems made of steel for free stan
25、ding 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 docum
26、ent 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. 2 Normative references Th

32、d the following, apply. 3.1 base supported liner liner which is supported vertically only at the liner base 3.2 independent liner base supported liner which has no other horizontal support or restraint 3.3 guided liner liner which has horizontal supports and/or guides allowing free expansion 3.4 top

34、iner 3.8 gas flow mass or volume of gas through the liner per unit of time 3.9 single wall chimney liner which also is bearing wind or seismic actions 3.10 turning vanes plates to lead the flue gas in another direction 3.11 prefabricated metal chimneys prefabricated metal chimneys or liners in accor
35、dance with EN 1856-1 and EN 1856-2 DINEN 13084-6:2016-02EN 13084-6:2015 (E)6 4 Material 4.1 General Materials used, shall be based upon chemical, thermal and mechanical effects and shall fulfil the requirements of EN 13084-1 and EN 1993-3-2. Materials used shall not have a negative influence upon ea
36、ch other. If prefabricated metal chimneys are used the additional requirements of this document shall be fulfilled. 4.2 Steels Steels commonly used are given in EN 13084-7. Other steels shall meet the requirements of EN 1993-3-2 and EN 13084-1. 5 General design requirements 5.1 General Gas flow calc
37、ulations to determine the diameter of the liner are covered by EN 13084-1. Material expansion due to temperature shall be taken into account. For steel liners and prefabricated metal chimneys the class of chemical attack shall be in accordance with EN 13084-1. 5.2 Liner The liner shall be designed i
38、n such a way that it is able to take the actions caused by: permanent action; pressure; temperature; the interaction with the supporting and guiding system; construction, transport and erection. The expansion shall be based upon the temperature, and length or diameter of the liner. For prefabricated
39、 metal chimneys the free movement of the liner shall be guaranteed. 5.3 Liner details 5.3.1 Supports and/or guides Supports and/or guides shall be designed in such a manner that they are able to take the actions caused by: the lining system; the load bearing system; thermal transfer; construction, t
40、ransport and erection. DINEN 13084-6:2016-02EN 13084-6:2015 (E)7 For prefabricated metal chimneys the distance between horizontal supports shall not exceed 75 % of the manufacturers declared value as defined in EN 1856-1 and EN 1856-2 with a maximum of 3,0 m. Their free unsupported height above the
41、last support shall not exceed 66 % of the manufacturers declared value as defined in EN 1856-1 and EN 1856-2 with a maximum of 2,0 m. 5.3.2 Openings Where openings are cut into the liner, as for duct entries, instrumentation or inspection panels, the strength and the stability shall be verified incl
42、uding any imposed loads. Openings in the liner shall have corners radiussed. See 6.3 for details. If prefabricated metal chimneys are not able to fulfil the given criteria in 6.3 a welded inlet construction can be used according to the requirements of this document and EN 13084-7. The connection bet
43、ween the welded inlet construction and prefabricated metal chimney part shall be gas tight according to the class of the liner. The size of openings shall be dimensioned according to their use. Manholes shall have a minimum area of 0,28 m2and a minimum width of 0,45 m. Cleaning and inspection openin
44、gs shall be provided so that the bottom of the liner may be inspected and cleaned when necessary. If openings are enclosed within the windshield they shall be to the same standard of gas tightness as the liner itself. If a ventilated space is provided there shall be adequate provision for the inspec
45、tion of this space. 5.3.3 Drainage system Adequate means shall be provided to drain condensate. The drainage system shall be dimensioned and fitted according to the operating conditions. This code does not cover the removal and disposal of condensate or waste products from the termination point of t
46、he drainage system fitted by the chimney manufacturer. It should be noted that the condensate and waste products should not be allowed to freeze, nor cold air bleed back into the liner. 5.3.4 Seals, gaskets and jointing compounds If seals, gaskets or jointing compounds are used their influence on th
47、e structure shall be considered. 5.3.5 Expansion joints Expansion joints shall be designed to withstand movements due to thermal expansion, chimney and foundation movement, design pressures and flue gas composition in appropriate combinations. Expansion joints shall be to the same standard of gas ti
48、ghtness as the liner itself. 5.3.6 Chimney cap The chimney cap protects the space between liner(s) and windshield against the ingress of weather and flue gas. Consideration shall also be given to the effects of chemical attack. 5.3.7 Insulation Deviating from EN 13084-1:2007, 4.3.2, the insulation a
49、nd/or cladding shall be sufficient to ensure that under normal operating conditions the surface temperature, not including solar gain, does not exceed 50 C at an ambient temperature of 15 C where personnel protection is required. DINEN 13084-6:2016-02EN 13084-6:2015 (E) 8 Insulation shall be adequately supported to stop it slipping and/or sagging. This can be achieved by pinning and/or banding. Where insulation is not covered by cladding, it shall be covered with wire mesh,
