<p>A method for operating a burner system (Fig. 1A) safely which uses a standard burner curve (Fig. 1B) of carbon dioxide concentrations plotted against the percentage of air in the burner system and having an infection point (22). The method of the present invention must determine if the operation of the system is such that the concentration of carbon dioxide falls on the left side (24) or the right side (26) of the inflection point of the curve. If the measured concentration of carbon dioxide (CO2), when compared to a constant, falls within a range which is near the inflection point of the standard curve further adjustments would have relatively small effect on safety and efficiency of the burner system. If the measured (figure 2) concentration of carbon dioxide falls outside of the range, then air is injected into the burner system and the concentration of carbon dioxide is measured again. The difference between these two measured concentrations is determined. If the difference is less than a predetermined constant, the method ends. Otherwise, additional air is injected and the steps of the method are repeated.</p> |
