Residential fireplace insert system improvements

Abstract

This CIP titled “Residential Fireplace Insert System Improvements” involves an improvement in the efficiency of the slide-in “Residential Woodburning Fireplace Insert System”, formerly application Ser. No. 11/507,343 filed Aug. 21, 2006, (now Pat. No. 7,509,954) wherein the heat output and fuel consumption are improved by controllably shutting off free air flow into the the combustion chamber by using a framed panel of heat-tolerant plastic film (as an alternate to using the glass doors) at the surround door location, then controlling the generated heat and fuel combination by carefully injecting just the proper ratio of the oxygen-to-fuel necessary for controlling both the heat output rate and fuel consumption parameters which include soot and creosote control improvements.

1 . I claim an improvement in the art related to the parent application Ser. No. 11/507,343 filed Jun. 18, 2008 wherein a modification to the said parent application is so effective that radiated heat transfer is enhanced and controlled by the ability to shut off free normal oxygen combustion air intake into the combustion chamber by using a thin rigid metal frame with a taut, leakproof, stretched temperature-tolerant plastic film panel option in place of the usual glass closure doors, and using a plurality of air purge inlets located immediately behind and around the surround area to supply and control the necessary optimum fuel/air ratio combustion combination, the drilled said air purge inlets strategically arranged in the air pressure supply tubing constraint coming from the plenums which assist in the formation of a swirling turbulent inlet air action in near proximity to, directed generally parallel to, and to the rear of the film plane, additionally using one or more soot controls or similar smoke deflector means to prevent as much smoke deposit or similar accumulation as possible on the said temperature-tolerant plastic film panel and/or door closure, including a dome light centered over the said combustion area to render aid in observing and making possible fuel/air adjustments based on burning and flame pattern characteristics.
