Provided is a coke dry quenching facility including a cyclone instead of a conventional dust catcher as a primary dust catcher, the coke dry quenching facility having the configuration so as not to provide circulating cooling gas at about 1,000°C to the cyclone and enabling temperature rise of the circulating cooling gas to be about 1,000°C before reaching a boiler, thus preventing a decrease in heat recovery amount by the boiler without increasing the flow rate of the circulating cooling gas. A coke dry quenching facility 100 includes: a chamber 10, into which red-hot coke is supplied and circulating cooling gas is blown; a cyclone 20, into which circulating cooling gas is introduced via a first duct 70, the cyclone collecting coke powder; and a boiler 30, into which circulating cooling gas is introduced via a second duct 80, the boiler recovering heat of the circulating cooling gas. Circulating cooling gas having temperature controlled to be 900°C or lower is provided at the cyclone 20, and an air introduction path 40 to introduce air to circulating cooling gas is located at a part along the second duct 80 only. |
