35、 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 applications of such equipment have not been considered in the preparation of this Guide. This G
36、uide covers mechanical (steam or air) and acoustic sootblowers for the following applications: - furnace wall sootblowers and water lances; - long retractable and semi-retractable sootblowers; - rotating element sootblowers including rake sootblowers; - airheater sootblowers. The equipment covered b
37、y 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 potential purchasers how their specification sho
38、uld 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; - proper consideration is given to the
39、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 project strategy. it does not cover: - a
40、ny 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 comprehensive European environmental pol
41、icy 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 are cited in the appropriate place

45、.2 supplier: Person or organization that provides a product and/or a service to the purchaser. 3.1.3 specification: Document stating technical requirements of the purchaser. It may form part of an enquiry issued by a purchaser. 3.7.4 enquiry: Invitation to tender issued by a purchaser. It will norma
46、lly include a specification together with the necessary contractual and commercial conditions. 3.7.5 tender: Offer made by a tenderer in response to an enquiry. 3.7.6 tenderer: Person or organization submitting a tender for the equipment in response to the enquiry. 3.1.7 site: Place to which the equ
47、ipment is to be delivered or where work is to be done by the supplier, together with so much of the area surrounding as the supplier may, with the consent of the purchaser, use for the purposes of the contract. NOTE: Further definitions of useful organizational terms may be found in EN IS0 8402 (see
48、 Bibliography). 3.2 Technical terms 3.2.1 sootblower: Device which uses the impact of a jet of, steam, air or water, or sound energy (acoustic sootblower) to dislodge deposits from the internal surfaces of the boiler. 3.2.2 long retractable sootblower: sootblower which may be fully retracted from th
49、e boiler gas path when not in use. Rotation or part rotation is applied to give maximum tube coverage. 3.2.3 semi-retractable sootblower: Retractable sootblower part of which may remain in the gas stream when in the rest position without the need for cooling air. This device is also known as a helical or part retractable sootblower. 3.2.4 rake sootblower: Sootblower with multiple arms and nozzles which normally remains in the flue gas path without the need for cooling air when in the rest position. This device is also known as a traversing multi-jet sootblower. 3.
