Heat Extractor to Capture and Recycle Heat Energy within a Furnace

Abstract

A heat extractor captures and separates the heat and the carbon monoxide from waste energy that is expelled from the furnace as an unusable bi-product. The heat extractor includes a core assembly, a furnace flue pipe inlet, and a furnace flue pipe outlet. The heat extractor is secured within a return air duct of the furnace, while a furnace outlet is connected to the furnace flue pipe inlet and the furnace flue pipe outlet is connected to a chimney outlet. When the furnace is operating, the hot exhaust passes through the heat extractor on its way to the chimney outlet. Within the return air duct there is a heat exchange from the heat extractor to the return cool air, thereby preheating the cool air just before it enters the furnace causing less consumption of energy to heat that air while the carbon monoxide harmlessly passes through the chimney outlet.
