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. Reversing valve means are provided to supply air or lean gas through the headers to all of the vertical riser ducts of the "off" flues for admixture with the waste gas conveyed through the induction or recirculation ducts to the vertical riser ducts of the "on" flues to dilute the…
