Produktbeschreibung
Excerpt from Tests of Run-of-Mine and Briquetted Coal in a Locomotive Boiler In its investigation of more efficient methods for utilizing the coals and lignites in the United States, to the end that waste may be avoided, the value of low-grade coals increased, and the life of the nation´s fuel resources prolonged, the United States Geological Survey has carried on a study of the factors involved in the manufacture and use of briquets, including the suitability of various coals for briquetting, the cheapest and most satisfactory binders, and the furnace behavior and evaporative efficiency of briquetted fuel. The investigations began with the work done at the coal-testing plant at the Louisiana Purchase Exposition, St. Louis, Mo., in 1904, and were continued at St. Louis and later at Norfolk, Va., as an essential part of the scheme of technologic research by the government fuel-testing plant. Accounts of various tests and statements of the conclusions to be drawn from them have appeared in a number of bulletins. In connection with the work at Norfolk, comparative steaming tests were made in stationary, marine, and locomotive boilers with run-of-mine coal and the same coal formed into briquets of two sizes. The tests in a locomotive boiler that are described in detail in this bulletin were undertaken to add cumulative evidence to work done at other places. They were made possible through the courtesy of the Seaboard Air Line Railway Company in supplying both the locomotive and the coal used. During the trials the locomotive stood on a side track in the shop yards of the railway company at Portsmouth, Va. No running tests were made. Personnel. J. A. Holmes, expert in charge, technologic branch, United States Geological Survey, had general supervision of the investigation carried on at the Norfolk fuel-testing plant.
