<p>PURPOSE:To efficiently recover heat by directly supplying pressurized air to the red-hot coke fed into a quenching tower to partially burn combustible gas and the red-hot coke, and recovering sensible heat of the resulting high-temp. gas as steam. CONSTITUTION:A quenching tower 1 is constituted by installing a reserve chamber 2 above a cooling chamber 3. The red-hot coke discharged from a coke oven is fed via a feed hopper 11 to the reserve chamber 2, into which inert gas is introduced from the bottom of the cooling chamber 3 and contacted with the coke to effect heat exchange, and the sensible heat of the coke is recovered. Simultaneously, pressurized air is introduced via a pressurized air supply conduit 9 installed above the reserve chamber 2 into said chamber 2 to partially burn combustible gas, fine coke and the red-hot coke within the chamber 2. The sensible heat of the resulting high-temp. gas is recovered together with the sensible heat of the inert gas in the form of steam by a waste heat boiler 6.</p> |
