Comparative Tests of Run-of-Mine and Briquetted Coal on Locomotives

Description: From Introduction: "For purpose of procuring data that could be using in estimating the value of the briquetting process as applied to American fuels, the United States Geological Survey, in cooperation with other interests, began in 1904, at the Louisiana Purchase Exposition, certain experiments involving the production and use of bituminous-coal briquets."

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."

Briquetting Tests at the United States Fuel-Testing Plant, Norfolk, Virginia, 1907-8

Description: From Briquetting Tests: "The briquetting work undertaken at Norfolk had these specific objects: 1. To determine what percent of pitch or other binder was necessary to make a satisfactory briquet out of the coals tested. 2. To investigate the relative merits of different binders. 3. To provide briquets for comparative combustion tests of run-of-mine coal and the same coal briquetted."

The Effect of Oxygen in Coal

Description: From Introduction: "This paper is the result of a comparative study of ultimate coal analyses made and published by the United States Geological Survey. The initial comparisons, made from a relatively small number of analyses, not only confirmed a previous conviction that the elimination of oxygen incident to the development of a coal is economically far more important than has been generally suspected, but also showed that oxygen is very nearly as harmful as ash in coal."

Incidental Problems in Gas-Producer Tests

Description: From Introduction: "In the course of this study many incidental problems of prime importance have demanded consideration. Among them is the determination, under practically constant conditions, of the duration of gas-producer tests necessary to reduce the possible error to minimum. A discussion of this proper length of test period forms the part of this bulletin."

Features of Producer-Gas Power-Plant Development in Europe

Description: From Introduction: "Because the limited time available would not permit a careful inspection, much less a detailed study of all the plants visited, the writer has not aimed in this bulletin to present a comprehensive review of producer-gas power-plant development in Europe, or even to give such conclusions as might be drawn from what he saw, but has simply described some interesting features of European practice that attract the attention of even a casual observer."

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

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

The Uses of Peat for Fuel and Other Purposes

Description: From Introduction: "The bulletin sets forth the results of an investigation that was undertaken to determine whether peat, a fuel widely used in some countries, could be made serviceable in the United States, where, through labor and economic conditions differ from those in peat-using countries, there are opportunities for the introduction of a fuel selling at prices that should make the mining and shipment of peat to near-by markets profitable."
