This European Standard shall be given the status of a nat
23、ional standard, either by publication of an identical text or by endorsement, at the latest by April 2000, and conflicting national standards shall be withdrawn at the latest by April 2000. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following count
24、ries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. This standard takes the form of a recommendation and
25、 is therefore entitled a “Guide“. This Guide for procurement has been prepared under mandates given to CEN and CENELEC by the European Commission and the European Free Trade Association. This Guide for procurement is a part of a series of Guides mandated to cover the procurement of power station pla

34、 for use in the procurement of power station plants. EN 4551 O is the responsibility of JTFPE. The so called “common clauses“, 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
35、definitions, clause 3. In this Guide, words and sentences not in italics are specific to this Guide and refer to the particular equipment covered. OBSI 01-2000 Page 6 EN 4551 04-1 0:1999 i Scope This standard gives guidance on writing the technical specification for the procurement of processes and
36、equipment for the removal of nitrogen oxides from the flue gas of 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 possible applicat
37、ions of such equipment have not been considered in the preparation of this Guide. This Guide covers: - Selective Catalytic and Selective Non-Catalytic Reduction Systems (SCR and SNCR); - systems to meet specific flue gas nitrogen oxide discharge requirements; - systems applying different types of am
38、monia-based solutions as reagent; - systems applying urea or compounds containing NH radicals as a reagent. 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
39、by a detailed descripfion 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, particularly - predicted performance is achieved; - a
40、ncillary 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. the boiler plant; This Guide does not determine the type of specification (e.g. detailed, performa
41、nce, 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 which a
42、re 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 implications of the equipment. 2 Normative references This Gu
43、ide for procurement incorporates by dated or undated reference, provisions from other publications.

47、 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 enquiry: Invitation to tender issued by a purchaser. It will normally include a specification together with the necessary contractual and commerc
48、ial 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 response to the enquiry. 3. i. 7 site: Place to which the equipment is to be delivered or where work is to be done by the supplier, togeth
