ABSTRACT:
In a dry type method and apparatus for quenching coke wherein hot coke charged in a coke quenching installation is cooled by circulating cooling gas in the installation through a closed circulating system including a blower and a heat exchanger, the composition of the cooling gas is analyzed and compared with a reference gas composition and air or nitrogen gas is supplemented to the closed circulating system in accordance with the result of comparison. A portion of the circulating gas is discharged to the atmosphere when air or nitrogen gas is supplemented. Air is supplemented on the high temperature discharge side of the circulating cooling gas while nitrogen gas is supplemented on the low temperature inlet side. The cooling gas is discharged to the atmosphere before the supplementation of the nitrogen gas.
