Book excerpt: Excerpt from Experiments With Superheated Steam: Thesis About this time, high pressure steam came into extensive use and the superheating of steam was abandoned. With the introduction of hydrocarbon lubricating oils, balanced valves and improved packing, the use of considerably higher temperatures became possible, and in 1890, interest in superheated steam was renewed by the at - tention drawn to the results being accomplished in Germany by such engineers as Gehre, Schwoeter, Uhler and others. Many results were published, all of which showed a gain from the practice and in England, in addition to the introduction to their apparatus, sever - al other types were developed along similar lines. Since that date the progress of superheating in stationary practice has been comparatively steady, although slow, and it has in general developed along the lines of moderate superheat, say from 50 degrees to 100 degrees, no special type of engine or boiler being usually employed and its subsequent history, with one exception, concerns stationary and marine practice rather than locomotives. That exception is the use of highly superheated steam, perfected after 14 years' ex - perimenting by Mr. Wilhelm Schmidt, of Cassel, who succeeded about 1894 in producing a boiler and engine in which steam, superheated to 700 degrees F. Was used at comparatively low pressures. Moderate superheating, employing temperatures up to 150 degrees above that of evaporation, first scientifically investigated by Hirn, ihtroduced extensively into early English marine practice by Penn and others and then abandoned; continued in stationary practice in AI - About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
