1. An improved combustion device for an outdoor flame heater, comprising:
a housing with an inside space for installing a gas barrel; a base mounted on the housing, including a gas intake tube and a gas control switch; a burner mounted on the base; a plurality of support members having a bottom end fixed on the housing to define a mounted space therein; a glass tube disposed in the mounted space; the burner including a top surface extending to define a gas distribution room over said gas intake tube; the top surface forming a plurality of tubular flame holes communicating with the gas distribution room and directed towards the glass tube, the top surface extending to a flange surface fastened to the base; a bottom surface of the gas distribution room being connected to the gas intake tube; wherein said flame holes have a diameter which is at least 10 mm for the flame to be in red and yellow, and a piece of metal wire mesh with a sieve size between 20-30 mesh abuts thereto from under in the gas distribution room, so as to construct a structure with a relatively greater diameter above and a relatively lesser diameter below; and a cover covering the burner to delimit an air distribution room between the burner and the cover, the air distribution room receiving gas projected through the flame holes for combustion therein, the cover having a plurality of airflow holes formed therein; a top of the cover having a recessed mounted hole for receiving a bottom end of the glass tube; the glass tube thereby having a lower opening located above the plurality of flame holes and the air distribution room for receiving and guiding a flame therefrom. |
