35、 the technical specification for the procurement of fans, ducts and dampers associated with steam generating plant and flue gas treatment plant for use in electricity generating stations (power stations). This guide for procurement is not applicable to equipment for use in the nuclear reactor plant
36、area of nuclear power stations. Other possible applications of such equipment have not been considered in the preparation of this guide. This guide covers: primary air fans and exhauster fans; secondary air fans, forced draught fans and induced draught fans; flue gas recirculating fans and flue gas
37、booster fans; modulating dampers and shut-off dampers; diverters and guide vanes; lined and unlined flues and ducts; thermal/acoustic insulation and cladding. The equipment covered by this guide is defined by its function rather than design type. Therefore, the guidance to the specification is state
38、d in performance terms rather than being specified by a detailed description of the equipment to be supplied. This guide indicates to potential purchasers how their specification should be prepared so that: the equipment type and capacity interfaces correctly with other elements of the systems; pred
39、icted performance is achieved; ancillary equipment is properly sized; reliability, availability and safety requirements are achieved; proper consideration is given to the evaluation process and the quality measures to be applied. This guide does not determine the type of specification (e.g. detailed
40、, performance, functional) or the extent of supply for any given contract which is normally decided on the basis of the purchasers project strategy. It does not cover: any commercial, contractual or legal issues which are normally in separate parts of an enquiry; any allocation of responsibilities w
41、hich are determined by the contract. This guide does not prescribe the arrangement of the documents in the enquiry. NOTE As a comprehensive European environmental policy is still in preparation, this guide does not address the environmental implications of the equipment. 2 Normative references This
42、guide for procurement incorporates by dated or undated reference, provisions from other publications. These normative references are cited in the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publ
43、ications apply to this guide only when incorporated in it by amendment or revision. For undated references, the latest edition of the publication referred to applies.

45、recipient of a product and/or a service provided by a supplier 3.1.2 supplier person or organization that provides a product and/or a service to the purchaser 3.1.3 specification document stating technical requirements of the purchaser. It may form part of an enquiry issued by a purchaser 3.1.4 enqu
46、iry invitation to tender issued by a purchaser. It will normally include a specification together with the necessary contractual and commercial conditions 3.1.5 tender offer made by a tenderer in response to an enquiry 3.1.6 tenderer person or organization submitting a tender for the equipment in re
47、sponse to the enquiryPage 5 EN 45510-4-3:1999 BSI 09-1999 3.1.7 site place to which the equipment is to be delivered or where work is to be done by the supplier, together with so much of the area surrounding as the supplier may, with the consent of the purchaser, use for the purposes of the contract
48、 NOTE Further definitions of useful organizational terms may be found in EN ISO 8402 (see annex A). 3.2 Technical terms 3.2.1 draught plant a combination of equipment comprising fans, ducts, dampers etc. which together form a system for transferring and controlling gas and air 3.2.2 primary air fans
49、 fans supplying the air required to transport pulverized coal from the coal mills to the boiler furnace. The fan draws air from either within or outside the boiler house (cold primary air fans) or from downstream of the airheaters (hot primary air fans) 3.2.3 forced draught fans fans supplying all or a large proportion of the combustion air to a steam generating plant. The fan draws its air from either within or outside the boiler h
