Abstract
TWO reports issued by the Canadian Department of Mines (“Peat, Lignite, and Coal,” by B. F. Haanel; “Report on the Non-Metallic Minerals Used in the Canadian Manufacturing Industries,” by Howells Frechette; Ottawa, 1914) are further examples of the sedulous care with which the Canadian Government is endeavouring to foster the industry of mining in the Dominion. The report upon peat, lignite, and coal deals exclusively with the application of these fuels to the generation of power-gas and to the recovery of by-products, the latter being chiefly ammoniacal salts. An elaborate study has been made of the various methods of dealing with peat in Europe, although, for some reason not easy to understand, Russian practice appears not to have been included, in spite of the fact that conditions in Russia resemble more closely those in Canada than do any of the other countries investigated. The first part of the report is taken up with a discussion of the various methods of producing peat fuel; it is interesting to note that the author has devoted a good deal of attention to the well-known Ekenberg process of wet carbonisation, and that his conclusions are decidedly unfavourable to the process. He points out that the most recent report on the subject by Lassen shows “that in continuous operation on a large scale, a moisture content below 70 per cent, in the pressed cake cannot be counted on,” and dismisses the subject with the following statement:-
