The LNCB{trademark} project involves retrofitting the two-nozzle cell burners at Dayton Power & Light`s, 605 HWe J.M. Stuart Unit {number_sign}4 Boiler near Aberdeen, Ohio with LNCB{trademark} (a burner and intregal NOx port). Previous pilot-scale tests have shown such an arrangement to achieve 50% reduction in NOx emission levels. This full-scale project will determine the commercial applicability of this technology. Fabrication and installation of all materials for the burner inversion and impeller change was completed during this quarter. The outage work, which began April 27th and concluded with the unit returning on line May 9th, went very smoothly. The parametric testing phase of the project actually began May 14th after correcting test equipment problems. Preliminary results show that the impeller change and burner inversion were successful. The Low NOx Cell{trademark} burners achieved better than 50% NOx reduction and carbon monoxide (CO) inside the lower furnace is less than 1000 ppm.
