Title:
COKE DRY QUENCHING FACILITY
Document Type and Number:
WIPO Patent Application WO/2014/041919
Kind Code:
A1
Abstract:
Provided is a coke dry quenching facility that, while applying a cyclone in the place of a conventionally structured dust collector set forth as a primary dust catcher, adopts the countermeasure of not supplying circulating cooling gas that is on the order of 1000°C to the cyclone, and moreover does not have a reduced amount of heat recovery by a boiler without increasing the flow rate of circulating cooling gas by increasing the temperature of the circulating cooling gas before entering the boiler to be on the order of 1000°C. The coke dry quenching facility (100) is provided with: a chamber (10) to which red-hot coke is supplied and to which the circulating cooling gas is blown; a cyclone (20) into which the circulating cooling gas is introduced via a first duct (70) and that recovers coke powder; and a boiler (30) into which the circulating cooling gas is introduced via a second duct (80), and that recovers heat from the circulating cooling gas. The circulating cooling gas of which the temperature has been controlled to no greater than 900°C is supplied to the cyclone (20), and an air introduction pathway (40) that introduces air to the circulating cooling gas is present only at a position partway along the second duct (80).
