Excerpt from North Dakota Lignite as a Fuel for Power-Plant Boilers Acknowledgments - Credit is due to A. A. Storrs and G. O. Sanford, the Reclamation Service engineers directly in charge of the Williston project, who had all changes made in the boiler - plant equipment that were necessary for the tests. J. M. Fine, engineer in charge of the power plant, and John G. Cunningham both rendered valuable assist ance in connection with the operation of the boiler under test. Related investigations - The fuel researches of the Geological Survey, which had their beginning under an appropriation made by Congress on February 4, 1904, for testing fuel at the Louisiana Purchase Expo sition, embraced not only the field study of mineral - fuel deposits, but also analyses and tests to determine the quality of the deposits, their adaptability to specific uses, and the methods by which they could be utilized to best advantage. In the course of these investigations the Survey collected and analyzed thousands of samples and made a great number of tests, such as washing, briquetting, coking, steaming, and producer-gas tests, to ascertain the fuel value of the peat, lignite, or coal under fixed conditions, its relative suitability for a given purpose, and the possibility of increasing its efficiency. Results of these tests are given in many of the bulletins listed at the end of this report. The act of Congress of May 16, 1910, which established a Bureau of Mines, transferred to this bureau the work of analyzing and testing fuels that was being carried on by the Geological Survey. The act became effective July 1, 1910. Hence the Bureau of Mines is publishing a considerable number of reports, of which this is one, dealing with investigations made by the Geological Survey prior to that date. Objects of the tests - The primary object of the tests was to show that the lignite coals of North Dakota are suitable for making steam. The secondary objects were to determine the effect of the size and the weathering of coal on economy and to determine whether anything is gained by superheating the steam used in the Argand steam blowers.
