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. By thermostatically controlling the valve which controls gas passage through the ambient air inlet branch conduit, the proportion of hot and relatively cool ambient gasses and consequently the temperature of the mixed gasses will be regulated since the gas pump or fan continues to transmit a fixed gas volume to the drying kiln.
