Abstract
By providing a heat exchanging vessel which employs no moving parts and is interposed in the exit flue between the furnace and the chimney, an efficient energy recovery system is achieved which prevents hot air from escaping without any benefit. In the preferred embodiment, the energy saving system of this invention optimizes normal convection currents and air flow paths to eliminate the necessity for any moving parts or electrically driven equipment, as well as incorporating fin members to increase surface areas for heat transfer and heat radiation.
Claims7
An energy recovery system for installation in a furnace output flue line, comprising
- A. a heat exchanging vessel adapted for mounting directly in the furnace output flue line and incorporating
- a. an inlet portal for receiving output hot gas from the furnace,
- b. a flue outlet portal for delivering said furnace air to a chimney flue, and
- c. baffle means for controllingly diverting the furnace output hot gas through a pre-defined path;
- B. first duct means positioned within the heat exchanging vessel and extending the entire length thereof, substantially along the central vertical axis of the heat exchanging vessel, and incorporating
- a. an inlet portal located at the bottom of said first duct means for receiving ambient air,
- b. a first outlet portal positioned at the top of said first duct means for delivering the warmed ambient air, and
- c. a duct defining wall member cooperatively associated with the interior of the heat exchanging vessel to form therewith a heat transfer zone wherealong the ambient air rising through the duct means is continuously warmed;
- and
- C. a shroud member peripherally surrounding the upper portion of the heat exchanging vessel and comprising
- a. a shroud inlet portal formed at the base of said shroud for receiving ambient air, and
- b. a second outlet portal spaced above said shroud and positioned for delivering the warmed ambient air to a pre-determined heating zone,
- wherein the first outlet portal from said first duct means and the second outlet portal of said shroud merge within second duct means for carrying said warmed air directly to a zone wherein heated air is required, whereby the total aspiration of air is increased.
