ACCELERATING CHARGING OF RAW MATERIAL COAL IN COKE OVEN

PURPOSE:To obtain high-quality coal, by charging a carbonizing chamber with coal to be fed with accelerating properly the speed of the coal itself without using a fluid for transporting the coal to be fed, controlling the acceleration according to the packing degree of the coal to be fed in the carbonizing chamber so that the bulk density and the bulk density distribution of the coal to be fed are regulated. CONSTITUTION:In charging a carbonizing chamber of a coke oven of the chamber furnace type with coal to be fed, the coal to be fed is packed from the hopper 1 of a charging car equipped with a high-speed charging mechanism for the coal to be fed into the carbonizing chamber, sent from the bottom of the hopper to the feeder 2 for the coal to be fed, the coal to be fed itself is accelerated to a proper velocity and packed into the carbonizing chamber by the projecting mechanism 3b like a three- stage impeller in the casing 3a of the projecting device 3 for the coal to be fed connected to the feeder using the driving gear system 4 such as the variable speed electric motor 4a, the reduction gear 4b, etc. attached to an impeller shaft without using a fluid for transporting the coal to be fed, and the raw material coal is fed to the carbonizing chamber by controlling the acceleration according to the packing degree of the coal to be fed in the carbonizing chamber so that the bulk density and the bulk density distribution of the coal to be fed are regulated.
