ABSTRACT:
A furnace for manufacturing a high-calorific gas and coke from coal, provided with two walls 1 perforated in their upper portion, which form a rectangular chamber 2 filled with a coal charge. These walls are provided with channels 3 with inlet pipes 4 for supplying hot combustion gases and the furnace is furnished in its upper zone with inlet pipes 6 for delivering coal to the furnace and ramming pistons 7 having imparted free reciprocating motions. At the side of the furnace in its upper zone are inlet pipes 8 for supplying a hot circulating gas to the direct heating chamber where a coal charge is directly heated. Inside of the gas chamber 10 of the furnace there is an outlet pipe 9 for withdrawing cold circulating gas to a blower 14, which then becomes successively heated to the required temperature in a heat exchanger 13.
