35、Annex A (informative) Bibliography 16Page 4 EN 45510-4-6:1999 BSI 09-1999 1 Scope This standard gives guidance on writing the technical specification for the procurement of processes and equipment for the removal of sulfur oxides from the flue gas of steam generating plant for use in electricity gen

36、erating stations (power stations). This guide for procurement is not applicable to equipment for use in the nuclear reactor plant area of nuclear power stations. Other possible applications of such equipment have not been considered in the preparation of this guide. This guide covers: wet, semi-dry

37、and dry systems; systems to meet specific flue gas discharge requirements, for example sulfur content, dust content and temperature; systems with and without marketable by-products; systems to meet specified waste product discharge limits; systems to meet limited choice of absorbent type and limitat

38、ion of water consumption. The equipment covered by this guide is defined by its function rather than design type. Therefore, the guidance to the specification is stated in performance terms rather than being specified by a detailed description of the equipment to be supplied. This guide indicates to

39、 potential purchasers how their specification should be prepared so that: the equipment type and capacity interfaces correctly with other elements of the systems particularly the boiler plant; predicted performance is achieved; ancillary equipment is properly sized; reliability, availability and saf

40、ety 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, performance, functional) or the extent of supply for any given contract which is normally decided on

41、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 which are determined by the contract. This guide does not prescribe the arrangement of the documents in

42、the enquiry. NOTE As a comprehensive European environmental policy is still under preparation, this guide does not address the environmental implications of the equipment. 2 Normative references This guide for procurement incorporates by dated or undated reference, provisions from other publications

43、. 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 publications apply to this guide only when incorporated in it by amendment or revision. For undated refe
