10、to The First EditionThe authors dedicate this book to their distinguished colleague on Subcommittee I, the late Walter Harding of Combustion Engineering. From the 1950s until his retirement in the 1980s, Walter Harding served with distinction on the ASME Boiler and Pressure Vessel Committee in many

11、capacities, including Chairman of the Main Committee. An engineer of the greatest integrity, Harding was an inspiring role model for younger committee members, extremely knowledgeable, ever helpful, cheerful, and the possessor of a fine sense of humor. We were fortunate to have had the privilege of

12、serving with him.The authors of the Second Edition dedicate this book to their esteemed colleague on Section I, the late Martin D. Bernstein. Martin (Marty to most of his good friends) served with passion and dedication from the early 1970s un-til his untimely passing in 2002, at which time he was V

13、ice-chairman of the Committee. In addition to his duties on Section I, Marty was an active member of the ASME Committee on Safety Valve Requirements, serving as Vice- Chairman from 1990 and Chairman in 2000. We were fortunate to know Marty and to have had the pleasure of his company during the frequ

47、essional development course on Section I explained that Section I contains the rules for the construction of power boilers, but that those rules are accompanied by very little explanation. Thus, the course was intended to provide a basic understanding of those rules, their intent, and how they are a

48、pplied, interpreted, and revised. This book is a greatly expanded version of those course notes, with broader and more detailed coverage on various topics of interest to those involved with power boilers.Author John MacKay was asked to take on the task of updating this book. He recruited Jim Pillow,

49、 friend and BPV I colleague, to assist with the effort. John and Jim accepted the challenge as a way to honor the accomplish-ments of Martin and Lloyd and to carry on their work. Both Martin and Lloyd spent their careers working for major boiler manufacturers and decades serving in various capacities on the ASME Boiler and Pressure Vessel Committees. Likewise, John and Jim have spent their careers involved in the design, manufacture, and installa-tion of power boilers and continue their decades of
