Clark, D R

This patent describes a heating appliance employing a radiant burner that burns a combustible gas comprised of a mixture of gaseous fuel and combustion air and that emits radiation while burning the combustion gas, having means for suppling the gaseous fuel to the radiant burner at at least one flow rate and have means for controlling the rate of supply of the combustion air to the radiant burner, a method of setting the proportion of the gaseous fuel to the combustion air in the combustible gas to a desired proportion. It comprises setting and gaseous fuel supply means at a given flow rate; measuring the unmodulated intensity of the radiation; deriving a control partner based on measurements of intensity of the radiation taken while varying the combustion air flow rate; and applying the control parameters to the means for controlling the rate of supply of the combustion air so as to reach and maintain a flow rate of the combustion air that results in the desired proportion.
