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."

Briquetting Tests of Lignite at Pittsburgh, Pennsylvania, 1908-9 : With a Chapter on Sulphite-Pitch Binder

Description: From Results of Briquetting Tests: "The results of the briquetting investigations conducted by the Government are expected to prove of considerable value, not only to the Government itself as the owner of extensive lignite deposits and largest single purchaser of fuel, but also to the people living in the the regions where lignite is found. The problem assumes still larger proportions when one realizes that the development of manufacturing industries in those regions depends upon the ability to obtain a cheap and satisfactory fuel. Although the results presented in this bulletin are not conclusive, they warrant the continuation of the investigators as soon as funds can be available for the purpose."

Combustion of Coal and Design of Furnaces

Description: 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."
