Abstract
A desired oxygen/fuel ratio is maintained for a combustion process when the heat required from the combustion process is substantially constant. Excess oxygen is provided to the combustion process in response to an increasing fuel flow resulting from an increase in the heat required of the combustion process by initiating an increase in the flow of an oxygen-containing fluid before the fuel flow rate is increased in response to an increasing heat requirement. When the heat required of the combustion process is decreasing, the reduction in the flow rate of the fuel is initiated prior to initiating a reduction in the flow rate of the oxygen-containing fluid. In this manner, excess oxygen is provided to a combustion process even when the fuel flow rate is not at a steady-state condition.
