Patent
·
OSTI ID:5392446
A low NO /SUB x/ burner for a furnace and a method of operating the burner involving a primary and secondary combustion zone wherein staged fuel and air to both combustion zones 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 and injection of the remaining fuel with the remaining 10% of the air to a secondary reaction zone the formation of NO /SUB x/ is significantly suppressed. Such a burner is useful in minimizing NO /SUB x/ emissions for a variety of furnace types including both natural draft and forced draft furnaces.
