Abstract
An apparatus includes a housing into which a hazardous gas is introduced. A sleeve in the housing includes a perforate segment into which the gas is discharged along with flows of oxygen delivered from sleeve mounted nozzles. Particles forming in a sleeve defined mixing zone gravitate toward a first collection site within the housing. Within the housing are radially spaced tubular members through which the gas and oxygen mixture flows in a serpentine path with provision for the collection of particles precipitating from the flow adjacent one end of the housing. Metallic fibers render any gas collection in the housing inert. Provision is made for delivering, in the alternative, a pressurized air flow to the sleeve for oxidizing the hazardous gas flow utilizing ambient air. A diffuser plate imparts current to the ambient air discharged into the sleeve.
