  • Method and apparatus for suppressing the deposition of carbonaceous material in a coke oven battery
    Patent number: 3963582
    Abstract: In one embodiment valve means are provided in the pipe connecting the fuel gas main and air supply main to the respective headers to simultaneously supply a portion of the air to the headers associated with the "on" flues and a portion of the air to the headers associated with the "off" flues. The air supplied to the headers associated with the "on" flues mixes with and dilutes the rich fuel gas to suppress the tendency to deposit carbon in the vertical riser ducts of the "on" flues. The air supplied to the headers associated with the "off" flues removes the carbonaceous material deposited in the vertical riser ducts of the "off" flues. In another embodiment induction or recirculation ducts are provided between the vertical riser ducts of interconnected flues to admix a portion of the waste gas from the "off" flues with the rich fuel gas flowing upwardly through the vertical riser ducts of the "on" flues.
