The size of the oven is 32 feet long,6J feet high, 19\ inches wide at the charging end, and 20 J incheswide at the discharging end. The average coking time is about33 hours, so that each oven can carbonize 40 tons of slackper week, yielding 27J tons of coke. Slack Stamping, Coke Charging, and Coke Discharging machine is self-contained, made by MM. Buchanan &Son, Liverpool. It is electrically operated, a 35 Mather & * Read before the Wolverhampton and District Engineering Societyn dated with this Society), on March 26th, 1920. 158 COAL AND ITS COAL AND ITS BY-PRODUCTS. 159 Piatt motor being used for charging, and a 10 M. & for the stampers. From the storage bunker the slackis transferred into a stamping box on this machine where it iscompressed into a heavy compact cake, weighing 8 tons. Thecake is then passed into the oven by mechanical means afterthe coke has been discharged. In the oven the slack is subjected to a temperature of about1,000° C. for 33 hours, at the end of which time the ovens areopened. When the slack is subject to the intense heat of 1,000° C. inthe ovens, the volatile gases it contains are driven off and passaway by means of the ascension pipes and hydromains to largevessels called condensers. These may be either vertical orhorizontal. Some vertical condensers contain a large numberof tubes through which cold water is circulated and as the hotgases come in contact with the outsides of these tubes, they arecooled to the temperature of the atmosphere. At the same time,as a result of thi
