Automatic fuel combustion control method and system
 Combustion of fuels each containing at least one combustible component, wherein, while the composition of each combustible component is known, the mixture ratio of only one combustible component is yet unknown, is automatically controlled by: measuring the flow rate of each fuel, the flow rate of air for the combustion, and the percentage proportion of residual oxygen in the combustion exhaust gas; introducing the values thus measured as input into a combustible component ratio detector comprising an operational circuit according to a combustion reaction formula thereby to automatically determine the unknown combustible mixture ratio; multiplying this mixture ratio by a flow rate signal corresponding to the same fuel; and utilizing the resulting product value for automatic control of the flow rate of each fuel and the combustion air.
