1.7 Lignite Combustion - US EPA

The installation shown in the pictures was performed on a 450 MW cyclone fired boiler that was designed to fire North Dakota Lignite. The unit has since converted over to burn sub-bituminous coal from the Powder River Basin. A first generation overfire air system was implemented in the 1990's to lower NOx as directed by the Clean Air Act.
