An inlet and outlet opening between ambient room air and the interior of a device are used with a sensor. Flame arrestor quench screens are used to control a fire within a chamber having an impeller causing air flow. A pilot flame situated within the combustion chamber burns combustible gas while temperature, pressure, and oxygen sensor devices are used to modify air flow as necessary for optimum combustion within the device.

at Rotary Flame Heater By www.freepatentsonline.com Published On :: Thu, 15 Jun 2017 08:00:00 EDT This invention relates to a rotary flame heater, comprising a burner, a first wind wheel, a second wind wheel and a glass tube set in sequence from bottom to top; one side of the burner is set with an ignition device, the first wind wheel and second wind wheel are annular, a plurality of first air inlet passages are aslant set on a side wall of the first wind wheel, a plurality of second air inlet passages are aslant set a side wall of the second wind wheel, the inclined direction of the plurality of first air inlet passages is the same with that of the second air inlet passages. The advantage of this invention is to make full use of the combustion space, increase the contacting area with the glass tube and increase the calorific value when burns the same gas, which achieves a better heating effect.

at METHOD AND APPARATUS FOR DIFFUSE COMBUSTION OF PREMIX By www.freepatentsonline.com Published On :: Thu, 15 Jun 2017 08:00:00 EDT A method directs fuel-oxidant premix into a reaction zone through a first total premix inlet flow area, and causes the premix to combust and form a stable flame projecting into a process chamber through an outlet from the reaction zone. At a time when the process chamber has a temperature at or above an auto-ignition temperature of the fuel, the flame is blown off to initiate diffuse combustion in the process chamber without a stable flame. The flame is blown off by directing the premix into the reaction zone through a second total premix inlet flow area greater than the first total premix inlet flow area. Full Article
at DOUBLE-SEALED HIGH-TEMPERATURE RESISTANT DC IGNITOR FOR USE WITH WOOD PELLET BURNER ASSEMBLIES By www.freepatentsonline.com Published On :: Thu, 22 Jun 2017 08:00:00 EDT Embodiments of the inventive concept provide a double-sealed high-temperature resistant DC ignitor for use with a wood pellet burner assembly. The DC ignitor includes a non-heating element portion. The non-heating element portion is connected to at least one of a battery or an AC to DC electrical transformer attached to the wood pellet burner assembly. A heating element is connected to the non-heating element portion, and extends by at least one inch into a combustion region of the wood pellet burner assembly. The heating element portion is configured to be heated by power received from the battery or the AC to DC electrical transformer. The DC ignitor provides safe, reliable, and fast combustion of wood pellets that congregate in a combustion region of the wood pellet burner assembly. Full Article
