Abstract: A system for the combustion of waste products for the extraction of heat energy in a clean pollutant-free medium. The system includes a swirling air-cyclonic type incinerator having means for controllably consuming fuel in the form of waste products of various grades and heating values. Incinerator outlet means are provided for transmitting gaseous combustion products to a heat exchanger, a filtering device, and ultimately to a point of beneficial utilization. Through a plurality of ducts, control valves, and pumping means, a selectably variable volume of oxygen necessary to support combustion is taken from the ambient. The remaining gas flow to the incinerator for such purposes as creation of a swirling flow and cooling is pumped from the outlet side of the heat exchanger.

Abstract: A system for the combustion and utilization of waste products for the production of heat energy in a clean pollutant-free medium. The system includes forced air swirling-type incinerator having means for controllably admitting fuel in the form of waste products and having exhaust stack means for removal of combustion medium in the form of heated gases therefrom. The system further includes a particle removal and retention arrangement for treating the heated combustion medium from the incinerator and for removing both gross and miniscule particulate therefrom before transmitting said medium to a point of beneficial utilization. The particle retention arrangement includes revolving screen means and washing means therefor as well as filter means disposed to intercept the heated medium passing through the revolving screen means.

Abstract: A dual function thermal recovery system for reducing pollutant emissions to the ambient and for utilizing normally wasted heat energy for beneficial purposes. A simple and efficiently operative assemblage of components for directly transmitting outlet stack gasses from an incinerator to a point of utilization such as a wood drying kiln, heat exchanger, or the like. A conduit connected directly to the outlet gas stack of the incinerator directs such outlet gas to the inlet of a constant volume centrifugal gas pump. Proximate the inlet of the gas pump, a branch conduit intersects the hot gas conveying conduit. An automatically thermostatically controlled valve is located within the branch conduit in selectively blocking relationship to relatively cool ambient air. An exhaust conduit is connected directly to the outlet of the gas pump for directing the output of such pump to a point of direct utilization, such as a drying kiln.
