Abstract
Abstract A coke oven system is provided having a coke oven preferably with pipeline charging for converting coal into coke. Carryover fines are collected from the coke oven and preferably a preheater therefor, and then agitated by agitator means and the collected carryover fines thereby agglomerated. Preferably, the carryover fines are first mixed with water to form an aqueous mixture, and then agglomerated. The agglomerated carryover fines are then preferably separated from the aqueous mixture by separated means. The agglomerated carryover fines are preferably conditioned in dryer means and recirculated to the coke oven preferably through a preheater.
