25、andards Information Centre, 06 April 2005, Uncontrolled Copy, (c) BSIEN 13084-6:2004 (E) 5 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 lin

26、ers 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 w

27、ith 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 The following referenced documents are indispensable for the applic

33、ly 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 hung liner liner which is supported vertically at the top 3.5 sectional steel liner li

34、ner with at least two independent vertically supported sections 3.6 liner support load bearing component which supports the liner 3.7 duct entry part of the liner which introduces the flue gases into the liner 3.8 gas flow mass or volume of gas through the liner per unit of time 3.9 single wall chim

35、ney liner which also is bearing wind 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 accordance with EN 1856-1 and EN 1856-2 4 Material 4.1 General Materials used, shall be based upon chemical, th

36、ermal 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 each other. If prefabricated metal chimneys are used the additional requirements of this document shall be fulfilled. Licensed Copy: Wang Bin, ISO/Exc

37、hange China Standards Information Centre, 06 April 2005, Uncontrolled Copy, (c) BSIEN 13084-6:2004 (E) 7 4.2 Steels Steels commonly used are given in prEN 13084-7. Other steels have to meet the requirements of EN 1993-3-2 and EN 13084-1. 5 General design requirements 5.1 General Gas flow calculation

38、s to determine the diameter of the liner are covered by EN 13084-1. Material expansion due to temperature has to 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 in such

39、 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, length and diameter of the liner. For prefabricated metal ch

40、imneys 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, transport

41、and erection. For prefabricated metal chimneys the distance between horizontal supports shall not exceed 75 % of the manufac- turers 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 last support shall not exceed 66 % of the manufac

42、turers 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 including any imposed loads. Openings in the liner sh

43、all have corners radiused. See 6.3 for details. Licensed Copy: Wang Bin, ISO/Exchange China Standards Information Centre, 06 April 2005, Uncontrolled Copy, (c) BSIEN 13084-6:2004 (E) 8 If prefabricated metal chimneys are not able to fulfil the given criteria in 6.3 a welded inlet construction can be

44、 used according to the requirements of this document and prEN 13084-7. The connection between the welded inlet con- struction 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

45、have a minimum area of 0,28 m and a minimum width of 0,45 m. Cleaning and inspection openings 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

46、 itself. If a ventilated space is necessary there shall be adequate provision for the inspection 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 co

47、ver the removal and disposal of condensate or waste products from the termination point of the drainage system fitted by the chimney manufacturer. It should be noted that the condensate and waste prod- ucts should not be allowed to freeze nor cold air bleed back into the liner. 5.3.4 Seals, gaskets

48、and jointing compounds If seals, gaskets or jointing compounds are used their influence on the structure shall be considered. 5.3.5 Expansion joints Expansion joints shall be designed to withstand movements due to thermal expansion, chimney movement, design pressures and flue gas composition. Expansion joints shall be to the same standard of gas tightness as the liner itself. 5.3.6 Chimney cap The chimney cap protects the space between liner(s) and windshield against the
