Excerpt from A Study of Four Hundred Steaming Tests: Made at the Fuel-Testing Plant, St. Louis, Mo. In 1904, 1905, and 1906 It is also the intention of the boiler division to study the principles of fuel combustion to such advantage that much coal can be saved, and that cheap fuels can be used in certain operations where higher priced ones are now considered necessary. Such savings Will really redound to the benefit of producers of the best fuels of all grades quite as much as to the benefit of consumers. A number of new lines of work are suggested in the text; several of these it is planned to take up soon, and some of them may give data for determining the burning qualities of fuels independently of the apparatus in which the process takes place. Perhaps the most important reason for doing the research work, and for making SO many comparisons Of the data Obtained from all tests, was the feeling that the testing of fuels under boilers is at best only approximately comparative. In Short, it was the feeling that we were on the wrong track, without knowing Of a better one, which led us to do the research work.
