<p>Burner [10] for a furnace and a method of operating the burner [10] involving a primary [22,38] and secondary [28,46] combustion zone wherein staged fuel and air to both combustion zones [22,38;28,46] is provided. By injection of from about 40% to 60% of the liquid or gaseous hydrocarbon fuel along with about 90% of the total air required to a first reaction zone [22,38] and injection of the remaining fuel with the remaining 10% of the air to a secondary reaction zone [28,46] the formation of NOx is significantly suppressed. Such a burner is useful in minimizing NOx emissions for a variety of furnace types including both natural draft and forced draft furnaces.</p> |
