Operational / Human Error Event Rate Investigation And

Air Quality Control Maintaining air quality control systems in service at lower loads presents a special challenge. Nitrogen oxides (NO x) can generally be controlled by combustion down to about 40% load with proper tuning and controls. NOx will increase as load drops from about 40 to 25%; in this case, the selective catalytic reduction (SCR) system goes out of service.
