Abstract
867,654. Briquettes. SCHLYTER, B. Nov. 13, 1958, No. 36535/58. Class 55 (1). A continuous process for producing briquettes of combustible material comprises mixing finely divided combustible material with a binding agent and forming the resulting mixture into briquettes of desired shape, drying and coking the briquettes by supplying them into a tunnelshaped elongated furnace provided with conveying means for the briquettes, continuously conveying the briquettes in the tunnel in succession through a low-temperature drying zone in the vicinity of the charging end of the tunnel and subsequently through a high-temperature coking zone closer to the discharge end thereof for coking the briquettes while introducing into the tunnel hot burnt or burning gases through at least one gas inlet substantially in the middle section of the tunnel, causing the hot gases to flow in the travelling direction of the briquettes in the high-temperature zone of the tunnel and substantially in countercurrent to the briquettes in the drying zone by sucking off gases through at least one outlet at the discharge end of the tunnel and a minor quantity of gas at the charging end thereof and recirculating the latter gases to the tunnel after heating them in a combustion chamber, discharging the briquettes from the tunnel and cooling them. The process may be carried out in apparatus comprising a tunnel furnace 6, 7 (6 constituting a low-temperature drying zone and 7 a high-temperature coking zone) having charging and discharging ends, means for charging briquettes into the furnace and conveyer means 6a for transporting them through the furnace. Gases evolved in coking zone 7 may be extracted by a fan 10 into a combustion chamber 3 where mixed with air they are burned, and returned to the furnace. In the modified apparatus of Figs. 3 and 4 tunnel furnace 21 is equipped with charging funnel 22, conveyer 24a, gas ducts 26, 33, fan 35a and combustion chamber 30.
