Pulverized Coal as a National Asset

THE profitable disposal and utilization of much of our slack coal, lignite, and other low-grade fuels is one of the major problems facing the coal mining industry of Canada today. It is my belief that the pulverization process applied to these fuels opens the door to greater efficiency and greater prosperity, and I wish to discuss briefly with you some features of its development and advantages to date. Indeed, the art of burning pulverized coal under stationary boilers is one of the romances of modern engineering. As a Nova Scotian, I feel some pride in the fact that at Chignecto Mines, N.S., was built in 1906 the first pit-mouth power plant on the North American continent. This was built to make effective for the first time Edison's dream of carrying coal for power by wire rather than by rail. This plant, built by the Maritime Coal, Railway and Power Company, Limited, success-fully utilized underfeed stokers for twenty years but in 1927 was replaced by a more modern plant equipped with machinery for burning pulverized coal, which is now operating very successfully. A further source of pride is the fact that the first boilers on this continent to be operated by pulverized coal were installed by the Dominion Coal Company at New Waterford, N.S., in 1912 and were satisfactorily operated during the lifetime of the plant. It is an acknowledged fact that average living conditions on a large part of the North American continent are far superior to those of any other people on earth. The reason is that we use so much more machinery per capita, and cheap power supply has been a large factor in bringing that about. Statistics show that where one horse-power was used one hundred years ago to assist man in his work, five hundred horse-power is used today. Truly a remarkable development and the key to our present high standard of living. Lack of coal in the chief industrial centres of Canada has forced the extra-ordinary development of the water powers which Providence has placed in those centres. How many of us realize that Canada stands second in the world in the per capita development of hydro power, Switzerland being first and the United States sixth? From this condition, we are reminded of the fact that the per capita foreign trade of Canada far exceeds that of our great neighbour to the South-but another illustration of the benefits accruing from our great power development.
