453,362. Gaseous - fuel furnaces. DIDIER-WERKE AKT.-GES., 90, Westfalische Strasse, Wilmersdorf, Berlin. March 18, 1935, No. 8440. Convention date, March 19, 1934. [Classes 51 (i) and 51 (ii)] A vertical-retort furnace for the production of gas and coke is combined with a gas producer having one or more circuitous channels at the side or above for conveying heating gas from the producer to the channel for distributing gas to the burners. As shown in Fig. 1, gas from the producer 1 passes through circuitous channels 2, 3, 6 one on each side of the producer, to the distributing channel 7 leading to the burners 8. The partition walls separating the channels 3, 6 are provided with openings 4 which are controlled by dampers. As shown in Fig. 3, recuperators 13, 14 are arranged on each side of the producer separated by a partition wall 15 having a damper controlled opening 16. Air admission openings 19, 20 are provided for the recuperators. By opening the dampers 19 and the dampers in the partition 15 air may be drawn through both recuperators in series and through the passage 9 to the burners. When it is desired to use extraneous gas either alone or in conjunction with producer gas, the extraneous gas may be admitted at 19 and pass through the recuperator 13 so as to enter the channel 6 through dampercontrolled openings 12, air being admitted at 20 to the recuperator 14.
