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

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

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."
