Abstract

PURPOSE:To avoid sudden combustion of combustibles at the time of opening of an oven lid and avoid dust accumulation in a water-sealed trough, by provid ing the trough attached to an upper oven wall of a cooling tower body with an air pipe through which air is introduced into the tower. CONSTITUTION:A circular water-sealed through 17 is fixed to an upper oven wall 16 of a cooling tower body 1 in coke dry quenching facilities, and sealing water 18 is accmmodated in the through. A seal metal 20 provided around an oven lid 19 which closes the top opening of the cooling tower body 1 is immersed in the sealing water 18. Prior to the opening of the oven lid 19, air bubbles are injected through an air pipe 25 disposed in the through 17, and are caused to advance through between the seal metal 20 and the inner wall 24 of the through 17 into the inside of the cooling tower 1. As a result, the combustibles remaining inside the tower are gradually burnt. Consequently, even if a large volume of air is introduced into the cooling tower 1 by opening the oven lid 19, the combustibles present therein do not undergo explosive com bustion.
