Five Hundred Tests of Various Coals in House-Heating Boilers

Description: From Introduction Purpose of Tests: "The tests on which this report is based were made during or before 1917 to obtain a measure of relative heating value and burning characteristics of the various fuels when burned in domestic heating furnaces with attendance comparable to that given ordinarily. In all, 184 different shipments of coals, of which 172 were from various mines in this country, were burned in four low-pressure heating boilers; 534 individual tests were made. The primary object of tests was to report on each individual coal, but it was considered advisable to summarize the results to if any general deductions could be made. This report gives some of the results of this study in condensed form."
