Tennessee Valley Authority production. Elemental phosphorus. A stack in the TVA phosphoric acid plant in the Muscle Shoals area. Phosphoric acid is produced in conjunction with the making of elemental phosphorus. The phosphorus, used in the manufacture of incendiary bombs and shells and of material for "smoke," is produced by smelting phosphate rock, coke and silica together in electric furnaces and condensing the resulting phosphorus gases. When surplus phosphorus is available it is converted into highly concentrated phosphatic fertilizer, much of which is shipped abroad under provisions of the Lend-Lease Bill

Hanna furnaces of the Great Lakes Steel Corporation. Detroit, Michigan. Coke oven pusher. A long square pusher is inserted through the entire section of the coke oven, thus pushing the coke out to the other side into the freight car. This coke oven is a modern by-product oven. All the gases and vapors liberated from the coal in the cooking processes are recovered. The coal is heated from fifteen to twenty hours in a temperature of about 1700 degrees F. The gases and vapors released by the coal are condensed for the recovery of such by-products as tar, benzol, and gas. At the end of the coking period, the incandescent coke mass is pushed into the quenching car

Science and research. Studies of non-coking coals. V.F. Parry, supervising engineer of the Golden, Colorado field station of the U.S. Bureau of Mines is "sighting a coke bubble." This procedure is used to determine if a given coke has changed its properties or it is similar to another coke. One gram of powdered coal is heated at 820 degrees centigrade for two and a half minutes. The resulting "bubble" is then compared with a standard chart to determine its characteristics, as revealed by the shape it has assumed. This research is part of a project to find ways of improving the quality of coke from western coal
