VERTICAL CHAMBER FOR THE CONTINUOUS DRY QUENCHING OF COKE

摘要

Continuous dry quenching of coke is carried out with an inert gas circulated through hot coke in a vertical chamber and through a heat exchanger. The vertical chamber comprises a top prechamber below a charging opening and a quenching chamber which is below the prechamber. The quenching chamber has a bottom gas entry and a bottom coke discharge. A gas exit between the prechamber and the quenching chamber supplies gas to the heat exchanger. A gas entry and/or a gas exit communicating with the top of the prechamber is used to control the flow of gas so that the temperature of the gas removed from the vertical chamber remains constant during quenching operations when there is a disturbance to the flow of coke.
