Book Description
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.

Book Description
Excerpt from Predicting Coke Stability From Petrographic Analysis of Illinois Coals Previously published curves based on coal petrography and coking data that have been used successfully in predicting the astm stability factor of coke were found to be not generally applicable to Illinois coals. Using Illinois coals or blends containing Illinois and other coals, petrographic analyses and coking data, derived from pilot coke oven tests, provided basic information for modifying these curves. The information is pre sented in this report. The application of petrographic data to the curves for predicting coke stability is demonstrated.

Excerpt from Methods of Analyzing Coal and Coke The loss Of weight by air-drying is not regarded as an accurate determination, and the air-drying loss reported in an analysis simply means that the sample lost the stated percentage of moisture before it came to a condition Of approximate moisture equilibrium with the air Of the room, at a temperature Of 30° to 35° C.

Book Description
Excerpt from Coke From Medium-Volatile and Illinois Coals Illinois coals have been used continuously in blends for metallurgical coke since the days of World War II. Their use has presented certain problems in blend ing procedure which have been studied both experimentally and on a commercial scale. Where proper procedures have been developed and followed, the use of Illi nois coal has been found advantageous, involving no sacrifice in coke quality and reducing over-all costs.

Book Description
Excerpt from Preheating Coal Blends as a Means of Increasing Coke Strength Coking results from these two blends indicate that when the stability of coke made from a blend of these as received coals is above 50, very little if any improvement in coke strength or sizing can be expected by preheating the blend to as high as 450° F. Three additional blends of these two coals were then studied with the med ium-volatile constituent reduced to 15, 10 and 5 percent respectively. Stabilities of the cokes produced from the as received coals were and respectively, in each case below 50, which for this study is considered a minimum strength index for satisfactory metallurgical coke.

Book Description
Excerpt from The Chemistry of Coke: Being the "Grundlagen Der Koks-Chemie" With the vast increase of the coal and iron industry of Germany since the establishment of the Empire, the chemistry of fuels, and especially the scientific chemical investigation of coal, has come to be regarded in that country as every day demanding a larger amount of attention. And certainly this view is not Without justification, for the annual production of coal in the kingdom of Prussia rose from (metrical) tons in the year 1870, to tons in the year 1880, and tons in the year 1890. During this period of twenty years, therefore, the output of coal has been almost trebled. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Excerpt from The Determination of Moisture in Coke It therefore seems probable that the circulation of dried air is unnecessary; that larger temperature limits than 104° to 110° Cv are permissible; that no appreciable gain in weight due to absorption of oxygen takes place on heating longer than one hour; and, finally, that practically all the moisture should be removed on heating the un pulverized coke to constant weight. If the latter procedure is per missible, the ever-present danger of loss of moisture during pulveriza tion Will be eliminated and it Will be possible to determine the moisture content of a shipment of coke With the same ease and simplicity as for iron ores.
