摘要

TITLE: A METHOD FOR CONTROLLED PREPARATION OF COAL BLEND FEED FOR COKE OVEN TO AVOID CHUTE-JAMMING. The present invention relates to a method for controlled preparation of coal blend feed for coke oven such as to avoid problems of chute jamming due to excessive moisture content in feed coal and a system for addition of oil-water emulsion through multiple spray nozzles on coal blend for coke oven. The system involves controlled feeding of an initial quantity of oil in a mixing tank by measuring and controlling the flow rate and by passing through strainers to remove any foreign particles; and also feeding an initial quantity of water depending upon the water content by measuring and controlling the flow rate and passing through strainers to remove any foreign particles; pre-mixing of the oil and water emulsion thus obtained takes place in said mixing tank by counter-flow principle. A recirculation pump subjects the pre-mixed water and oil emulsion to intense mixing. An emulsion pump operatively supply the emulsion mixture from said mixing tank to the spray points over the coal blend feed.
