Use of Oxygen to Improve Efficiency and Reduce Emissions from Combustion Systems

Over the last several years oxy-fuel combustion has received a great deal of attention as a way to mitigate CO2 emissions from stationary power sources.  However, the use of oxygen to reduce emissions is not new.  Many of the unique characteristics of oxy-fuel combustion, such as elevated temperatures, have been used in a wide range of furnaces to improve efficiency and reduce emissions.  This presentation will cover some of the important characteristics of oxy-fuel combustion, typical ways oxy-fuel combustion is applied in commercial systems, and examples of recent developments in oxy-combustion for power systems.


Dr. Lawrence Bool got his Ph.D. from the University of Arizona in 1993. Throughout his career Dr. Bool has been active in developing technologies that utilize oxygen to facilitate combustion of a wide range of materials, increase energy efficiency, and reduce pollutant emissions from combustion processes. Dr. Bool led the development and commercial installation of oxygen enhanced combustion to minimize NOx formation in coal fired boilers. Using his experience with coal combustion Dr. Bool also invented a process to produce activated carbon from coal using hot oxygen technology. Dr. Bool is currently leading the development of HOB technology to reform tar and methane from hydrocarbon streams, as well as syngas production by partial oxidation. He currently holds 24 patents.
