37、1998 1 Scope This standard gives guidance on writing the technical specification for the procurement of steam turbines driving generators for use in electricity generating stations (power stations). This Guide for procurement is not applicable to equipment for use in the nuclear reactor plant area o
38、f nuclear power stations. Other possible applications of such equipment have not been considered in the preparation of this Guide. This Guide covers: reheat and non-reheat turbine; back-pressure turbine whose exhaust will be used for process heating; condensing turbine whose exhaust is directly conn
39、ected to a condenser ; mixed pressure turbine; regenerative cycle turbine; extraction turbine; combined cycle turbine. This Guide for procurement of steam turbines has been prepared to be used with the existing European Standard EN 60045-1, it should, therefore, be read in addition and complementary
40、 to the European Standard. 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 t
41、o potential purchasers how their specification should be prepared so that: the equipment type and capacity interfaces correctly with other elements of the systems; predicted performance is achieved; ancillary equipment is properly sized; reliability, availability and safety requirements are achieved
42、; 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 the basis of the purchasers p
43、roject 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 the enquiry. NOTE As a compre
44、hensive 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. These normative references
45、are cited in the appropriate places in the text and the publications are listed hereafter.
