|Combustion Modification Control of Nitrogen Oxides, Taking Research From Concept to Implementation (EPA/600/F-95/012) August 1995
EPA's research and development of nitrogen oxide (NOx) control technologies by means of modifying the combustion process have played a major role in reducing stationary source NOx emissions by over 3 million tons (2.73 x 10^6 tonnes) annually and have led to at least three low-NOx burner technologies now being offered commercially by major equipment vendors. These accomplishments required an average total EPA investment of less than $4 million per year over the past 20 years.
NOx formed during the combustion process has been seen as a major air pollution problem since environmental issues first rose to the national forefront less than 30 years ago. EPA has been involved in the full scope of technology development, from investigations of the fundamental science of NOx formation to full-scale field demonstrations of new control technologies. EPA’s efforts have contributed to a reduction of NOx emissions, in part because of the New Source Performance Standards and the 1990 Clean Air Act Amendments, both of which are based on combustion modification control of NOx. EPA's Air and Energy Engineering Research Laboratory continues to investigate more effective and efficient control technologies and to transfer those technologies to markets both in the U.S. and abroad.
