Title: Keith C Kaufman: Innovator in Pulverized Coal Burner Technology

Introduction

Keith C Kaufman is an accomplished inventor based in Canton, OH (US). He has made significant contributions to the field of combustion technology, particularly in the development of burners that minimize emissions and fuel losses.

Latest Patents

Kaufman's notable patent is for a pulverized coal burner designed to achieve lower emissions and reduced unburned fuel losses. This innovative burner incorporates a transition zone within a low NO.sub.x burner. The design features a pulverized fuel transport nozzle surrounded by the transition zone, which effectively shields the central oxygen-lean fuel devolatilization zone from the swirling secondary combustion air. The transition zone serves as a buffer between the primary and secondary air streams, enhancing the control of near-burner mixing and flame stability. This is accomplished by creating limited recirculation regions that transport evolved NO.sub.x back towards the oxygen-lean fuel pyrolysis zone for reduction to molecular nitrogen. Additionally, alternate embodiments of the burner include options for natural gas and fuel oil firing.
