| 20090205634 | Residential fireplace insert system improvements - 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. | 08-20-2009 |
| 20120192854 | UNVENTED GAS FIREPLACE - An unvented gas fireplace in which air flow through a closed combustion chamber is controlled by means of a restriction in the air flow path through an outer plenum chamber surrounding the combustion chamber. The restriction in the air flow path through the plenum causes a pressure differential between the plenum and combustion chamber, forcing air from the plenum into the combustion chamber, where it is combusted and mixed with the cool air that has passed the restriction in the plenum, before the air mixture is exhausted into the surrounding room, thereby heating the room. | 08-02-2012 |

A baffle plate may be introduced in the secondary combustion zone to increase a combustion chamber temperature, encourage mixing of oxygen starved air with oxygen rich air and increase a residence time of the combustion gas within the combustion chamber. These aspects of the baffle plate promote more efficient burning of the biomass/fuel. Additionally, log lighter(s) may be disposed in the secondary combustion zone to increase a temperature of the combustion chamber for the purposes of reducing harmful emissions. | 08-02-2012 |
