    A gas burner comprising a burner plate (3) arranged within a closed combustion chamber (2), a mixing chamber (4) having a gas inlet(5) and an air inlet (6) located at the side of the burner plate reverse to that of the combustion chamber and a fan (7) for feeding the gas-air mixture from the mixing chamber through the apertures of the burner plate in the combustion chamber. The gas burner is provided with a burner plate having a low thermal conductivity, a redox detector (9) arranged within the combustion chamber above the burner plate and an electronic control unit (10) producing one or more output signals for controlling the supply of gas and/or air to the mixing chamber of the burner in response to the output signal of the redox detector being applied to its input. These latter provisions permit the burner to be operated with widely differing loads and gas compositions whilst maintaining an extremely low excess of air in the gas-air mixture resulting in correspondingly low CO- and NOx -concentrations in the exhaust gas of the burner. The gas burner of the invention can be used both in domestic gas appliances for the heating of air of water or for cooking and as a pilot burner for controlling the supplying or oxygen to large industrial burners.

    专利说明:

    The invention relates to a power system, namely to the combustion of gas-like fuel, and can be used both in household gas-using devices for heating air or water, or cooking, and as a pilot burner for controlling the supply of oxygen to large industrial burners.
    The purpose of the invention is to provide regulation in a wide range of loads and reduce the toxicity of combustion products.
    The drawing schematically shows a device for heating air or water, equipped with a gas burner.
    The burner contains a closed case 1, divided by a stabilizer in the form of a perforated plate 2 into the upper combustion chamber 3 and the lower mixing chamber 4 equipped with gas and air nozzles 5 and 6, and the fan 7. The burner also contains a sensitive oxidative and regenerative element 8, mounted in the chamber 3 above the plate 2, as well as the electronic control unit 9.
    Ptita 2 is made of low heat conductive material, for example, ceramics.
    Element 8 is provided with a heating element 10 for preheating it, maintaining it at a predetermined temperature and simultaneously for igniting the gas / air mixture in chamber 3.
    Element 8 may be made in the form of a carbon monoxide detector. A heat exchanger 11 is installed inside the chamber 3 for heating water or air.
    The input of unit 9 is electrically connected to the electrical resistance of the sensing element 8, and the output is connected to a 7 "fan and / or a gas and / or air flow regulator 12 (not shown) mounted on the gas and air nozzles 5 and 6.
    During the operation of the burner, air through pipe 6 and gas through pipe 5 is fed to the mixing chamber 4 to form a gas-air mixture, from where the fan 7 supplies this mixture through perforations in the stove 2 to the combustion chamber 3, where it is ignited using heating element 10 and burns The supply of a gas burner with a flat plate 2 having a low heat conductor

    by the sensitive element 8 installed inside the combustion chamber 3 above the plate 2 and the electronic control unit 3 producing one or more output signals regulating the supply of gas and / or air to the mixing chamber 4 in response to the input signal of the sensitive element 8, supplied to the inlet of block 9, it allows to operate with different loads and gas compositions over a wide range while maintaining an extremely low value of the excess air ratio in the gas-air mixture, which leads to correspondingly low concentrations of CO and N0, in products of combustion.
