Excerpt from Coking Coals of Illinois: Their Use in Blends for Metallurgical Coke Much of the research behind the development of the coal blend at Granite City, and of other blends utilizing Illinois coals, has been carried out in the lab oratories and pilot coke ovens at the Illinois State Geological Survey. The orig inal slot-type oven (reed, 1947) and the newer movable-wall oven (jackman, l955a) have been developed and operated so that coking results closely duplicate those obtained in commercial oven practice. Results of tests made with the pilot oven may be used, therefore, as a dependable guide to anticipate performance of an experimental coal blend in commercial ovens. We wish to thank the coke and steel companies that have furnished us with coals for these tests, and Illinois coal producers who furnished the No. 5 and No. 6 seam coals. We are grateful also to those of our own staff who have co operated in obtaining samples, operating the pilot oven, and making analyses of all coals and cokes.
