Benefits of technology
The present invention is a heat extractor that captures and recycling heat energy from the flue gas of a furnace. By capturing and recycling the heat energy, the efficiency of the furnace is improved without the need for an outside energy source. The heat extractor is portable and can be easily integrated onto the furnace. The invention is placed within the returned air duct of the furnace and connected to the flue pipe system. The technical effect of the invention is to improve the efficiency of the furnace and reduce energy costs for consumers.
Problems solved by technology
However, small amount of waste gas and heat energy are ventilated through a flue piping system of the furnace.
In other words, the furnace is not able to improve upon the standard 98% efficiency due to the heat energy that is lost as a wasted bi-product from the furnace.
Due to the rising electricity cost and natural gas cost, the operating cost of a furnace also tends to increase every year.
As a result, consumers often have to spend extra money to operate the furnace.

Embodiment Construction
[0013]All illustrations of the drawings are for the purpose of describing selected versions of the present invention and are not intended to limit the scope of the present invention.
[0014]The present invention is a heat extractor which captures heat energy from a discharged flue gas of a furnace as the discharged flue gas releases thought a flue pipe system of the furnace. More specifically, the present invention captures the heat energy of the discharged flue gas and recycles the heat energy back into the furnace though a return air duct of the furnace thereby pre-heating the cool air before it reaches the furnace. Since only the heat energy is isolated away from the discharged flue gas, the present invention still allows the carbon monoxide bi-product of the discharged flue gas to release into the atmosphere through the flue pipe system. As a result, the present invention is able to improve the efficiency of the furnace without requiring an outside energy source while maintaining ...

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.
Description
FIELD OF THE INVENTION[0001]This invention relates generally to an apparatus that improves the overall efficiency of a furnace. More specifically, the present invention captures and separates heat energy from the carbon monoxide bi-product of the furnaces to preheat the return air, and then the preheated return air can be recycled back into the furnace to improve the efficiency of the furnace.BACKGROUND OF THE INVENTION[0002]Modern high-efficiency furnaces can be 98% efficient and operate with or without a chimney. However, small amount of waste gas and heat energy are ventilated through a flue piping system of the furnace. The flue pipe system normally vents through the side or roof of the house so that the waste gas and the heat energy can be effective discharged from the structure. In other words, the furnace is not able to improve upon the standard 98% efficiency due to the heat energy that is lost as a wasted bi-product from the furnace. Due to the rising electricity cost and n...
