Fuel and Mineral Briquetting

A Discussion of the Paper by Robert Schorr, read at the Atlantic City meeting, February, 1904. (Washington Meeting, May, 1905.) E. T. DUMBLE, Houston, Texas (communication to the Secretary*) :-In addition to the list of publications mentioned by Mr. Schorr and those by Prof. Hofman, I call attention to the following references : Studi sulle Lignite, by Capacci. Turin (1890). (An excellent work.) Report of Brown Coal Industry in Germany. J. Cosmo Newberry. Department of Mines, Victoria (1892). Second Report of the Royal Commission. on Coal Supply. Vol. II. London (1904). Peat Fuel: Its Manufacture and Use. Report of the Bureau of Mines of Ontario, 1903. Mr. Schorr says : " Brown coal and peat are briquetted as a rule without binder," but this statement is entirely true only so far as raw peat is concerned, and it is but partly true of brown coal. With regard to raw peat, briquetting without bond is carried on successfully both in Europe and America, and the development of the industry in Canada is fully described in the Bureau of Mines report for 1903, mentioned above. While there is still room for improvement in the efficiency of some of the arrangements for drying the peat previous to briquetting, a very satisfactory fuel is made at a price which enables it to compete with coal. During the late strike in the anthracite regions of Pennsylvania, the manufacture of peat: briquettes received a considerable impetus, and possibly the attention directed to it on this account may result in a. considerable increase in the output. In Canada. the peat when it is first excavated from the ground
