Boiler Trials, ICS # 2839, Edition 1, by A.S. Callen, published International Correspondence Schools, Scranton, Pennsylvania, 1948. Reproduced by Nation Builder Books, Mebane, NC, 2010, 5½ x 8½ photocopied booklet, 51 pages.
Please note this is a new photoduplicated reproduction, not an original.
What are the proper locations of the draft gauges during a boiler trial? What is the approved method of finding the weight of water fed to a boiler during a trial? What is the best location for a sampling pipe conducting steam to a calorimeter and why? What is meant by equivalent evaporation?
If you can answer all these questions, maybe you don’t need this book. But if you’re of the growing number of live steam enthusiasts looking for information to help you design and build an engine, then you will love this book. And be sure to look for our two dozen other reproduced books from this ICS series on steam railroading as taught and practiced in the 1930s and 1940s.
