Low-Temperature Distillation Of Illinois And Indiana Coals - Discussion (b2cba9e5-1530-4227-a305-a66a323fe150)

C. M. GARLAND,§ Chicago, Ill. (written discussion 11).-7--In the development of Mr. Traer's method for the low-temperature coking of Illinois coals, after the principles laid clown by Prof. Parr, it was soon demon-strated that, in order to yield a product of uniform volatile content, the coal must be coked in thin layers, and consequently must be handled in comparatively small volumes. This means, in the first place, that great care must he observed in the design of the coking chambers to prevent the loss of the products of distillation, and, in the-second place, that labor-saving devices must be utilized to the greatest possible extent in order to reduce the cost of handling.
