Phase 1 of a study to expand the performance and life-cycle cost data base for NOx control of gas-fueled prime movers has been accomplished through experimental evaluations of fuel effects, technical literature reviews of Japanese and domestic approaches to NOx control and through direct contacts with manufacturers and users in the United States and Japan. Engine tests confirm literature findings that natural gas and methanol provide an advantage over petroleum fuels in limiting NOx formation. For lean-burn engines (e.g., two-cycle and gas turbine engines), selective catalytic reduction offers the greatest amount of NOx control. Installation, operating and maintenance costs are very high; the method has received moderate acceptance in Japan but limited use in the United States. For rich-burn engines, nonselective catalytic reduction is gaining acceptance for NOx control. This method is basically the adaption of automotive three-way catalyst technology. Further RandD is recommended for alternative methods of NOx control which include combustion-cycle modifications and noncatalytic exhaust aftertreatment.
