ABSTRACT:
A gas combustion method and apparatus for performing such comprises supplying a fuel gas, generating a gas mixture composed of the fuel gas and external air, diffusing the gas mixture through a diffusion member to lower a flow velocity of thereof, putting the gas mixture to flaming combustion in a cylindrical combustion chamber thereby elevating the temperature of a combustion catalyst disposed to the downstream end of the combustion chamber by the heat of the flaming combustion, then ceasing the diffusion of the gas mixture to increase the flow velocity thereof in the combustion chamber, thereby extinguishing the combustion flame and directly supplying the gas mixture to the combustion catalyst. The gas mixture is put into and out of diffusion by an actuating mechanism that brings a diffusion member into and away from the entrance of the combustion chamber.
