EN 45510 is the responsibility of JTFPE. The so called “common clauses”,
26、as appropriate, also appear in italics in the documents specific to particular equipment. In this Guide, words in bold type indicate that they have the meaning given in the Definitions clause 3.

35、on for the procurement of equipment for ash handling associated with coal-fired steam generating 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 area of nuclear power stations. Other poss
36、ible applications of such equipment have not been considered in the preparation of this Guide. This Guide covers mechanical conveying systems which handle the ash mechanically. Among those are, for example: submerged scraper conveyor; ram-type slag extractor; belt conveyor; drag-link conveyor; vibra
37、tory conveyor; screw conveyor; apron conveyor; bucket elevator; skip hoist; vehicles. Hydraulic conveying systems use water as conveying medium. These include, for example: water-filled ash hopper; dry ash hopper; sluiceway; slurry pump with pipeline; ejector with pipeline. Generally a combination o
38、f the above systems is employed. 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 indic
39、ates to potential purchasers how their specification should be prepared so that: the equipment type and capacity interfaces correctly with other elements of the systems such as the boiler and gas treatment plant; predicted performance is achieved; ancillary equipment is properly sized; reliability,
40、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, performance, functional) or the extent of supply for any given contract, which is
41、 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, which are determined by the contract. This Guide does not prescribe the arrangeme
42、nt of the documents in 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
43、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 publications apply to this Guide only when incorporated in it by amendment or rev
44、ision. For undated references, the latest edition of the publication referred to applies.
