ABSTRACT:
Process and apparatus for incinerating refuse or the like in a furnace where the flue gases of combustion are combined with secondary air for afterburning the gases in an afterburning zone. The flue gases are dammed before entering the afterburning zone so as to increase retention time of the flue gases in a zone of uniform temperature in the furnace space, then are accelerated in a venturi-like manner in the afterburning zone, and then are decelerated in a venturi-like manner in the afterburning zone. Secondary air is injected across the front of the afterburning zone in a direction opposite the flow of the flue gases so as to further increase the retention time of the flue gases in the furnace space, and so that the combustible components entrained in the flue gases are burnt completely before entering the afterburning zone.
