Hot coke produced in a coke plant is introduced into the lower portion of a sealed interior of a quenching tower. Quenching water is supplied to the hot coke, thereby cooling the hot coke and generating steam and quenching gases which rise from the quenched coke to the upper portion of the interior of the quenching tower. Condensing water is supplied into the upper portion of the interior of the quenching tower, thereby condensing the steam to form quenching water condensate. A water mixture of the condensing water and the quenching water condensate is collected at a midportion of the interior of the quenching tower, and such water mixture is prevented from passing to the lower portion of the interior of the tower. The thus collected water mixture is discharged from the interior of the quenching tower, and the quenching gases remaining in the upper portion of the interior of the quenching tower are removed without being directly discharged into the exterior surrounding environment.
