Excerpt from Factors Affecting Coke Size A pilot-plant study has been made of the relative amounts of foundry-size coke that may be produced from a blend containing Illinois coal by (1) addition of small amounts of anthracite fines, (2) similar additions of coke breeze, and (3) varying the coking time over a wide range. Results indicate that by adding 5 to 10 percent anthracite, coking time may be reduced 6 to 12 hours without decreasing the yield of large-size coke. There are cer tain changes in the physical properties of the coke. Where these changes are not detrimental to the ultimate use of the product, the addition of anthracite fines is an effective way to increase foundry-coke production. Although blast-furnace coke accounts for the major coke tonnage produced 1 used in the Chicago and St. Louis areas, plants producing foundry coke as it chief solid fuel product are located within shipping distance of the low fur coal fields of Illinois. Coking studies therefore have been made at the nois State Geological Survey on blends of Illinois coals with Eastern high llow-volatile coals at coking rates and temperature conditions calculated produce maximum yields of large foundry-size coke.
