Title: Innovations of Steve B Londerville
Introduction
Steve B Londerville is a notable inventor based in Half Moon Bay, California. He has made significant contributions to the field of combustion technology, particularly in the development of low NO.sub.x burners. With a total of four patents to his name, Londerville's work focuses on enhancing the efficiency and environmental performance of combustion systems.
Latest Patents
One of Londerville's latest patents is the vibration-resistant low NO.sub.x burner. This innovative burner design includes a primary air and fuel discharge assembly featuring a burner plate with multiple slots. These slots allow for the discharge of fuel gas jets and combustion air, arranged to create varying widths of recirculation zones. This unique construction leads to local ignition patterns that oscillate at different frequencies, effectively dampening vibrations and minimizing resonance issues in furnaces. In applications where high excess air is not desirable, such as in boiler systems, the burner can be modified to include a secondary fuel and flue gas injection assembly, forming a two-stage burner. This design lowers overall combustion temperatures, thereby reducing NO.sub.x formation.
Another aspect of his burner design involves a plurality of fuel tubes aligned with the slots for discharging fuel gas. The high-velocity discharge of fuel gas and combustion air generates significant turbulence in the combustion chamber, enhancing combustion efficiency. The arrangement of the slots and the inclusion of a central gas nozzle further contribute to flame stability, allowing for operation with up to 110% excess air without the need for air preheating.
