Tests of Coal and Briquets as Fuel for House-Heating Boilers (open access)

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

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."

Coal-Mine Accidents in the United States and Foreign Countries (open access)

Coal-Mine Accidents in the United States and Foreign Countries

From Introduction: "The lack of comparable and accurate statistics of coal-mine accidents in the united States as a whole led the Bureau of Mines in 1911 to undertake the collection of such data. The mining departments of the leading foreign coal-producing countries have long taken cognizance of the importance of statistics. The bureau feels that in presenting the tables embodied in this report it is offering the and comparable statistics of coal-min accidents for the country as a whole that have ever been published."

The Humidity of Mine Air with Especial Reference to Coal Mines in Illinois (open access)

The Humidity of Mine Air with Especial Reference to Coal Mines in Illinois

From Introduction: "The investigative work described in this report was undertaken by the Bureau of Mines under a cooperative agreement with the department of mining engineering of the University of Illinois and the Illinois and Illinois State Geological Survey. The purpose of this agreement was to provide for a comprehensive investigation of coal-mining conditions in the State, with especial reference to the possibility of lessening waste in the mining and preparation of coal and of reducing the dangers to which miners are exposed. Thus, it studied the occurrence of gas (methane) in the mines of the southern part of the State, tested the inflammability of the coal dust from many mines, examined the efficiency of the control of ventilating currents, and investigated the factors affecting the humidity of mine air with respect to their bearing on the occurrence of mine explosions."

Combustion of Coal and Design of Furnaces (open access)

Combustion of Coal and Design of Furnaces

From Purpose and scope of Investigations: "The combustion investigations of bureau are carried on in two parts. One part is the study of the process of combustion in the fuel bed as affected by the rate of supplying air through the fuel bed, by the character of the fuel as regards structure and composition, by the thickness of fuel bed, by the method of feeding the coal and the air and by the method of heating the coal. The second part of the investigation is the study of the process of combustion of the gases and other combustible rising from the fuel bed in the combustion space, after a sufficient quantity of air has been added. The results of the study are given in this report."

Recovery of Zinc from Low-Grade and Complex Ores (open access)

Recovery of Zinc from Low-Grade and Complex Ores

From Introduction: "Vocalization in retorts has been, until recently, the only commercial process of producing spelter, hence the zinc mine operators have had to meet the terms of the zinc mine operators have had to meet the terms of the zinc smelters in regard to the following requirements: (1) Minimum percentage of zinc the ore must contain; (2) the chemical combination of the zinc in the ore; (3) the proportion present of those elements that interfere with the successful recovery of the zinc when the ore is retorted. As stated previously, and as will be shown later, a large part of the valuable mineral content of the ore is lost in effecting this concentration. As a result of the other requirements that have to be met in zinc smelting, much zinc is lost in the mining and milling of zinc ore."
