Coals Available for the Manufacture of Illuminating Gas

Description: From Introduction General Statement: "The investigations were so directed as to permit the testing of coals from different parts of the united States. The results show that certain coals from which good yields of gas had been expected can not be considered as available for illuminating-gas manufacture, whereas other coals give promise and should investigated further. The data contained in this report are the outcome of the cooperative work at the laboratory mentioned during parts of the years 1… more

Comparative Tests of Run-of-Mine and Briquetted Coal on the Torpedo Boat Biddle

Description: From Introduction: "With the particular equipment used in the tests both coal and briquets were far from smokeless; consequently the data of this bulletin are applicable only by analogy to parallel operation with a coal more nearly smokeless, but nevertheless applicable with much reliability. It was the original intention to make a set of preliminary steaming tests alongside a dock (which tests furnish material for this bulletin) an to finish with a set of running tests at sea; but the running … more

A Primer on Explosives for Coal Miners

Description: From Introduction: "Much of the information in this primer has been obtained from experiments conducted by the technologic branch of the United Sates Geological Survey at the mining experiment station at Pittsburgh, Pa. These investigations have shown the recent development of a new type of short-flame explosives, which can be used with greater safety than black powder in mines where there is dangerous gas or inflammable dust, because the flame from the explosion of black powder lasts from 2,50… more

Tests of Coal and Briquets as Fuel for House-Heating Boilers

Description: From Introduction: "Perhaps the most important result obtained is that showing the relative value of different fuels for domestic purposes. From Table 16. on page 39, it is possible by comparison to arrive at the probable value of any fuel in any part of the country. The figures in the table show that with a sectional boiler the effectiveness of different fuels depends on the number of thermal units they contain. A brief summary of the results of this investigation is given on page 41."

Tests of Run-of-Mine and Briquetted Coal in a Locomotive Boiler

Description: From Object of Tests: "The primary object of the tests was to study the relative performances of the two types of briquets and of the coal, with reference to efficiency, tendency to smoke, and the ease with which steam could be kept up, when each of the three varieties of fuel was burned at several rates of combustion. Many secondary objects were in mind, the data concerning which are discussed under "Effect of varying rates of combustion," pages 20-27."
