ABSTRACT:
Apparatus for burning the gaseous and carbon particulate products from a kiln in which carbon is being calcined, including a pair of vertical cylindrical vessels, to which the effluent products of calcining are carried, by means of an input conduit, which enters the first vessel in a tangential manner near the bottom end, so that the gases will circulate circumferentially in a spinning flow inside of the vessel, as they progress upwardly to a outlet near the top of the first vessel, which leaves tangentially, and passes to the second vessel and enters it tangentially. The gases then circulate around the inner wall of the second vessel spin flowing downwardly, where they leave near the bottom to enter the stack. Means are provided on the entrance conduit for injecting combustion air into the inlet conduit prior to entry of the effluent products into the first vessel. Water may be included with the combustion air, if desired, which is sprayed into the combustion air, and mixes with the effluent products causing immediate combustion of the combustible gases, and of the carbon particles.
