EN 12952-13:2003 (E) 3ForewordThis document (EN 12952-13:2003) 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of an identical text orby endorsement, at the latest by September 2003, and conflicting national standards shall be withdrawn at the lat-est by September 2003.This document has been prepared under a mandate given to CEN by the European Commission and the EuropeanFree Trade Association, and supports essential requirements of EU Directive(s).For relationship with EU Directive(s), see informative annex ZA, which is an integral part of this document.The European Standard EN 12952 concerning water-tube boilers and auxiliary installations consists of the followingparts:¾ Part 1: General¾ Part 2: Materials for pressure parts of boilers and accessories¾ Part 3: Design and calculation for pressure parts¾ Part 4: In-service boiler life expectancy calculations¾ Part 5: Workmanship and construction of pressure parts of the boiler¾ Part 6: Inspection during construction, documentation and marking of pressure parts of the boiler¾ Part 7: Requirements for equipment for the boiler¾ Part 8: Requirements for firing systems for liquid and gaseous fuels for the boiler¾ Part 9: Requirements for firing systems for pulverized solid fuels for the boiler¾ Part 10: Requirements for safeguards against excessive pressure¾ Part 11: Requirements for limiting devices and safety circuits of the boiler and accessories¾ Part 12: Requirements for boiler feedwater and boiler water quality¾ Part 13: Requirements for flue gas cleaning systems¾ Part 14: Requirements for flue gas DENOX-systems¾ Part 15: Acceptance tests¾ Part 16: Requirements for grate and fluidized bed firing systems for solid fuels for the boilerCR 12952-17, Water boilers and auxiliary installations - Part 17: Guideline for the involvement of an inspectionbody independent of the manufacturerAlthough, these parts may be obtained separately, it should be recognised that the parts are inter-dependent. Assuch, the design and manufacture of water-tube boilers requires the application of more than one part in order forthe requirements of the European Standard to be satisfactorily fulfilled.NOTEParts 4 and 15 are not applicable during the design, construction and installation stages.Annex A is informative.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following coun-tries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,Slovakia, Spain, Sweden, Switzerland and the United Kingdom.SIST EN 12952-13:2003

Thesenormative references are cited at the appropriate places in the text and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision.

Pres-sures and loadings resulting from operating upset conditions and their consequences shall be considered sepa-rately. In such cases, the safety factor referred to the pertinent yield stress shall be at least 1.0.Temperatures below dew point, if any, and the consequences arising therefrom shall be prevented by suitablemeasures or by proper selection of materials. Additional effects such as corrosion/erosion attack by otherchemicals in the flue gas may be considered by wall thickness allowances, if required. The suitability of plantcomponents containing water-polluting substances shall comply with European Standards (e.g. prEN 12285).3.2The design shall be based on the load assumptions of EN 13445 unless deviations from these assumptionsoccur locally.For additional loadings not covered by the above mentioned standard the respective values shall be taken from thedesign data, in which case distinction has to be made between normal and abnormal operating load conditions.3.3Unfired pressure vessels included in the system shall be designed and manufactured in accordance withEN 13445.3.4The design shall assume that under any operating condition the flue gas pressure is not higher or lower thanthe value used in the design. Particular consideration of the damper positions and the heads of pumps and fansshall be taken into account.3.5The design of the components shall take into account the requirements for corrosion resistant materials, foritems such as linings and coatings.3.6Structural components of the flue-gas cleaning plant shall meet the relevant European Standards (e.g.ENV 1993, ENV 1994). Fire-protection requirements shall be taken into account.SIST EN 12952-13:2003
