17、European foreword This document (EN 12952-1:2015) has been prepared by Technical Committee CEN/TC 269 “Shell and water-tube boilers”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by end

18、orsement, at the latest by April 2016, and conflicting national standards shall be withdrawn at the latest by April 2016. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identif

19、ying any or all such patent rights. This document supersedes EN 12952-1:2001. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive 2014/68/EU. For relationship with EU Dire

20、ctive 2014/68/EU, see informative Annex ZA which is an integral part of this document. The informative Annex A lists the significant technical changes between this European Standard and the previous edition. EN 12952, Water-tube boilers and auxiliary installations consists of the following parts: Pa

DIN EN 12952-1:2016-02EN 12952-1:2015 (E) 5 1 Scope 1.1 General This European Stand

29、ard applies to water-tube boilers with volumes in excess of two litres for the generation of steam and/or hot water at a maximum allowable pressure PS greater than 0,5 bar and with a temperature in excess of 110 C as well as auxiliary installations (other plant equipment). The purpose of this Europe

30、an Standard is to ensure that the necessary essential safety requirements according to Annex I of the Pressure Equipment Directive are fulfilled in order to guarantee the safety of water tube boilers. This aim will be achieved by: the proper application of the design, manufacturing, testing and insp

31、ection methods and techniques, the provision of protective measures against hazards, which cannot be eliminated, and the provision of information on residual hazards and other measures to reduce risk, which are incorporated in the various parts of this European Standard. The requirements of this Eur

32、opean Standard take account of pressure-related hazards, which apply to water tube boilers, including failure of pressure-retaining components due to overheating. This standard recognizes that it is not possible to cover all the combinations of situations that might arise. 1.2 Boiler assembly For th

33、e purpose of this European Standard, the boiler assembly includes: the water-tube boiler including all the pressure parts from the feedwater inlet (including the inlet valve) up to and including the steam and/or hot water outlet (including the outlet valve or, if there is no valve, the first circumf

34、erential weld or flange downsteam of the outlet header); all superheaters, reheaters, economizers, that are not capable of isolation from the main system by interposing shut-off valves, associated safety accessories and interconnecting piping; additionally, the piping that is connected to the boiler

35、 involved in services such as draining, venting, desuperheating, etc., up to and including the first isolating valve in the tubing line downstream of the boiler; reheaters which are independently fired, and are separately provided with their safety accessories including all control and safety system

36、s. The following equipment and components can be integrated in the assembly at the discretion of the manufacturer: isolatable superheaters, reheaters, economizers and related interconnecting piping; the heat supply or firing system; the means of preparing and feeding the fuel to the boiler including

37、 the control systems; the means of providing the boiler with feedwater including the control system; DIN EN 12952-1:2016-02EN 12952-1:2015 (E) 6 the pressure expansion vessels and tanks of hot water generating plant. 1.3 Other plant equipment a) The boiler supporting structural steelwork, the therma

38、l insulation and/or brickwork and the casing; b) the means of providing the boiler with air including the forced draught fans and air pre-heaters which are heated by the gases of combustion; c) the facilities for moving flue gases through the boiler up to the stack inlet, including the induced draug

39、ht fans and the air pollution reducing equipment located in the flue gas removal path; d) all other equipment necessary for the operation of the boiler plant. 1.4 Exclusions This European Standard does not apply to the following types of boiler plant: a) boilers other than stationary boilers; b) she

40、ll type boilers; c) electrical boilers; d) nuclear primary circuits, the failure of which can cause an emission of radioactivity. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
