RAPID THERMAL DECOMPOSITION APPARATUS FOR COAL

PURPOSE:To obtain tar oil etc. with reduced facility and energy costs in an industrially advantageous manner by continuously feeding red coke discharged from a coke oven and coal having a regulated grain size into a reactor tube. CONSTITUTION:Red coke discharged from a coke oven 1 is received in a movable coke receiver 2. The receiver 2 is connected to a reactor tube 3, and coal pulverized and regulated to have a predetermined grain size (pref., up to 200 mesh accounting for about 70%) is continuously fed thereinto by means of a feeder 4. At the same time, the red coke is transferred from the coke receiver 2 to the reactor tube 3 so as to cause the red coke to be in contact with the pulverized coal. As a result, rapid thermal decomposition is performed. It is pref. that the reaction temp. be about 600-1,000 deg.C esp. about 650-850 deg.C, and that the reaction time be about up to 10 sec. Subsequently, the reaction products are fed through a char separator 5 and a cooler 7 to a liq. product separator 6 so as to collect the same.
