COKE DRY QUENCHING EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide coke dry quenching equipment capable of suppressing adhesion of clinker to a wall surface of a duct connecting a cyclone with a boiler.SOLUTION: A coke dry quenching equipment 100 comprises: 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 and which recovers coke powder; a boiler 30 into which circulating cooling gas is introduced via a second duct 80 and which recovers heat of the circulating cooling gas; and a third duct 90 connecting the boiler 30 with the chamber 10. A gas introduction passage 42 and air introduction passage 41 are connected to the second duct 80, and inert gas (circulating cooling gas) flowing through the gas introduction passage 42 and air flowing through the air introduction passage 41 are provided to the second duct 80.SELECTED DRAWING: Figure 1
