The Smokeless Combustion of Coal in Boiler Furnaces

Description: From Introduction: "The present bulletin not only shows that bituminous coals high in volatile matter can be burned without smoke, but also that large plants carrying loads that fluctuate widely, where boilers over banked fires forced to the capacity of their units, can be operated without producing smoke that is objectionable."

Description: Report discussing the results of investigations into the heat-absorbing abilities of the heating surfaces of boilers. Also discusses the laws that determine the rate of heat transfer from furnace gases through metal plates into boiler water and offers suggestions as to how these laws may be applied.

The Use of Permissible Explosives

Description: From Preface: "The present bulletin is printed as a supplement to Bulletin 17 and is intended primarily for coal miners, especially for those working in fields where inflammable gas or coal dust may cause disastrous mine explosions. The bulletin is issued by the Bureau of Mines in the hope that it may prove helpful in lessening accidents due to the use of explosives, and in particular may aid in preventing mine explosions, many of which have been caused by the use of improper explosives."

The Volatile Matter of Coal

Description: From Introduction Scope of Report: "This bulletin is a report on an investigation of the volatile matter in several typical coals-its composition and amount at different temperatures of volatilization. As the investigation is still in progress and will doubtless include other coals than those already examined, the bulletin may be considered a preliminary report, stating the problems studied, the methods used, and the results thus far obtained."

Apparatus and Methods for the Sampling and Analysis of Furnace Gases

Description: From Introduction: "It is the purpose of this paper to describe some apparatus and methods which have proved satisfactory to those engaged in the chemical work of the investigations mentioned. While these methods and apparatus have been designed more particularly with regard to analysis of furnace gases, their use is by no means limited to that purpose."

Binders for Coal Briquets: Investigations Made at the Fuel-Testing Plant, St. Louis, Missouri

Description: From Introduction: "The problem is always to produce at a profit a briquet of satisfactory grade for the use intended. This problem will be made clearer by a brief summary of the available binders, followed by a preliminary discussion of the characteristics of a good briquet."

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."

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 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."

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

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."
