16、 1960s, a substantial increase in the number of reported occurrences of steam turbinedamage by water induction precipitated design recommendations from the two major U.S. steamturbine manufacturers in an attempt to reduce such incidents. Consequently, utilities and designersbegan formulating their o
17、wn design criteria because of the economic need to keep the generatingunits in service. Realizing the common need for a uniform set of design criteria to alleviate thisproblem, an American Society of Mechanical Engineers (ASME) Standards Committee was formed,consisting of representatives of utilitie
18、s, equipment manufacturers, and design consultants todevelop recommended practices for use in the electric generating industry.This Standard, resulting from the work and deliberation of the Turbine Water DamagePrevention Committee, was approved as a Standard of The American Society of MechanicalEngi
19、neers by the ASME Standardization Committee and the ASME Policy Board, Codes andStandards, on July 26, 1972.In 1979, the Committee proposed a revision to this Standard to include information on condensersteam and water dumps, direct contact feedwater heaters, and steam generators. This proposedrevis
20、ion was approved by the ASME Standardization Committee on April 25, 1980.The 1985 revision was approved as an American National Standard on September 13, 1985. In1994, the ASME Board on Standardization approved the disbandment of the Committee onTurbine Water Damage Prevention along with the withdra
21、wal of the standard TDP-1. This wasdue to perceived lack of interest and use by the industry.Subsequent interest from users and potential users for TDP-1 convinced ASME to reconstitutethe Committee under the Board on Pressure Technology Codes and Standards in June 1997. Asa result of this committees
22、 work, TDP-11985 was revised and approved as an American NationalStandard on June 17, 1998.Advances in power plant technology, most notably combined cycle, multiple steam generators,cycling, cogeneration technology, and modern plant instrumentation and control systems, con-vinced the Committee to ag
23、ain revise the Standard. The result was TDP-12006. This revisionwas approved as an American National Standard on November 6, 2006.The current Standard is a revision of TDP-12006. The broad acceptance that this Standard hasreceived caused ASME to decide to reissue it in mandatory language rather than
24、 a recommendedpractice. In addition to the change to mandatory language, this revision also includes minormodifications and clarifications to the previous revision. This revision was approved as anAmerican National Standard on February 5, 2013.ivASME TWDP COMMITTEETurbine Water Damage Prevention(The
