35、1 Scope This standard gives guidance on writing the technical specification for the procurement of air heating equipment associated with steam generating plant and gas reheating equipment associated with flue gas treatment plant for use in electricity generating stations (power stations). This guide

36、 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 heat exchangers of the following types: indirect heating wit

37、h steam; rotary regenerative heaters; tubular/plate recuperative heaters; liquid coupled heat exchangers; heat pipes. This guide does not cover systems for direct contact heating of air or flue gas by hot gases. The equipment covered by this guide is defined by its function rather than design type.

38、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 potential purchasers how their specification should be prepared so that: the equipment type and capacity interfac

39、es correctly with other elements of the systems; predicted 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 n

40、ot determine the type of specification (e.g. detailed, 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 part

41、s of an enquiry; any allocation of responsibilities which 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 under preparation, this guide does not address the environmental imp

42、lications of the equipment. 2 Normative references This 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, su

43、bsequent amendments to or revisions of any of these publications 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. EN ISO 9001, Quality systems Model for quality assurance in design, developme
