Title: Innovations by David S. Neff in Low NOx Burner Technology

Introduction

David S. Neff, an innovative inventor based in Johns Creek, GA, has made significant contributions to combustion technology with a focus on reducing nitrogen oxide (NOx) emissions. His impressive portfolio includes two patents, showcasing his commitment to creating efficient and environmentally friendly combustion systems.

Latest Patents

David's latest patents include the "Low NOx Burner with Low Pressure Drop" and the "Ultra Low NOx Burner Using Distributed Direct Fuel Injection." The first patent describes a unique burner design that incorporates a cylindrical tube and an annular disk with a specific hole configuration. This design employs an oxidizer intake and fuel nozzle to create an optimal gas mixture, enhancing combustion efficiency while minimizing emissions. The use of elongated slots in the slotted member creates a complex velocity profile in the gaseous stream, which further contributes to the low NOx output.

The second patent presents a burner box featuring a housing with an open passage that allows vertical airflow. This design includes a fuel tube that distributes fuel through orifices, ensuring complete entrainment of the fuel by combustion air. The porous heat dissipating surface at the top of the housing effectively prevents flashback while allowing the fuel/air mixture to pass unimpeded, thus supporting a stable flame.
