<p>A method and apparatus for the recovery of gases issuing from a metallurgical refining furnace or converter, in which said gases are drawn off through a hood disposed above the outlet of the furnace and are entered as a gas column into a combustion chamber from which the burnt gases are drawn off by a main blower while air is simultaneously drawn from a space around the furnace adjacent to the inlet of said hood by means of an auxiliary blower and is forced into said combustion chamber to burn combustible components of said gases therewithin, the invention further including withdrawing a fraction of said combustible gases by sucking them from said gas column within the combustion chamber substantially before they are mixed with burnt combustion products generated within said combustion chamber to send said withdrawn fraction to utilization means which are external to said combustion chamber, and the invention further including the control of the rates of flow of the gases through various conduits in the system to optimize the desired operation.</p> |
