Not illustrated. 1916 edition. Excerpt: ...coal were used in 1909 to produce metallurgical coke for the blast furnaces of Great Britain; of this quantity, however, only 5,870,000 tons were coked in recovery ovens from which surplus gas was available for motive power. Used in gas engines, this gas would produce 150,000 BHP for 300 days at 24 hours per day, or 300,000 BHP for 300 12-hour days per annum. The conversion to recovery ovens is increasingly rapid, and when the whole 18 million tons is so coked, 460,000 BHP at 300 24-hour days per annum could be obtained. At present, however, but a small proportion is utilised. Coke oven gas varies considerably in composition and calorific power from hour to hour and day to day. Mr. Robson gives examples of this from one plant in England. Three days' test of the lower calorific value showed on the first day a minimum of 370 and maximum of 600 F. and 30 ins. mercury; on the second day tests showed a uniform 351 B.Th.U.; and on the third day minimum 345, and maximum 366 B.Th.U. The following table gives four analyses of this gas from different sources: The lower heating value may be taken to vary from 350 to 450 B.Th.U. per cub. ft. at atmospheric temperature and pressure, and the air required for complete combustion from 3 to 4 ft. per cub. ft. of gas. This variation, together with the high percentage of hydrogen in the gas, introduces difficulties in the application of the gas to driving internal combustion engines, but happily these difficulties have been met by providing means for the ready adjustment of the gas and air inlets, and further by a new method introduced by the author to prevent pre-ignition. An interesting installation of a modern coke oven plant is found at the Bargoed Colliery of the Powell Duffryn more
