Abstract (en)
[origin: EP2258810A1] It is intended to provide a CO concentration control method and apparatus for a coke dry quenching facility, which is capable of suppressing a rapid increase in CO concentration during hot coke charging into the coke dry quenching facility. In a coke dry quenching facility designed to subject hot coke to heat exchange with a cooling gas consisting of an inert gas, in a quenching tower of the coke dry quenching facility, and blow CO-burning air into the cooling gas heated to a high temperature and discharged from the quenching tower, whereafter the cooling gas with the air is introduced to a boiler to recover heat therefrom, and the cooling gas cooled by and discharged from the boiler is circulated to the quenching tower, the air is blown at a flow rate which is increased at a rate of 10 to 95 Nm 3 /h per second with respect to an air flow rate to be blown during a normal operation of the coke dry quenching facility, from 150 to 15 seconds before initiation of hot coke charging into the quenching tower, and subsequently blown at a flow rate ranging from 0.7 × Q to 1.3 × Q, during a period between the initiation and completion of the hot coke charging, wherein Q is an air flow rate to be blown at an initiation timing of the hot coke charging.
