Title: NON-BYPASSABLE CATALYST ASSISTED APPLIANCES
Abstract:
A non-bypassable catalyst assisted appliance (100, 1000) includes, for example, a housing (112, 1112) having a combustion chamber (300, 1300) therein. The housing has a loading door opening (117, 1117) coverable by a door (116, 1116) for loading fuel into the combustion chamber, an air inlet opening (111, 1113, 1115) for receiving an air supply to the combustion chamber, and an exit opening (118, 1118) connectable to a flue (119, 1119). A catalyst combustor (200, 1200) is disposed between the combustion chamber and the exit opening. When the door of the non-bypassable catalyst assisted appliance is disposed in a closed position covering the loading door opening, gas from the combustion chamber is directed through the catalyst combustor, and out the flue. When the door of the non-bypassable catalyst assisted appliance is disposed in an open position allowing loading of fuel through the loading door opening to the combustion chamber, ambient air entering the loading door opening and gas from the combustion chamber are directed through the catalyst combustor, and out the flue.
