ABSTRACT:
The specification discloses apparatus and methods for recovery of coal fines and for recycling thereof incidental to a self-contained system for charging preheated coal into coke ovens. The apparatus enables a system for charging preheated coal into coke ovens to meet pollution control regulations. The apparatus comprises four circulating streams of liquid for carrying coal fines in a slurry, namely, the charge main liquor circuit, the excess recycle gas scrubber circuit, the charge line condenser circuit and the charge bin vent condenser circuit. The -28 mesh coal with the liquor from the various circuits goes to a clarifier or thickener. Floating fines from top and settled fines from the bottom of the thickener are pumped via a fines tank to filters from which the solid or coagulated fines are restored to the wet coal feed to the heaters. Tars developed in the recovery processes are utilized instead of adding oil to liquors in process, for various reasons, including facilitating flow of coal through the pipe lines of oven charging systems.
