The report describes tests to evaluate the performance characteristics of three Second Generation Low-NOx burner designs: the Dual Register burner (DRB), the Babcock-Hitachi NOx Reducing (HNR) burner, and the XCL burner. The three represent a progression in development based on the original Babcock and Wilcox DRB. Of particular interest was the identification of burner configurations which would be suitable for application in the EPA LIMB (Limestone Injection Multistage Burner) technology demonstration program at Ohio Edison's Edgewater Station, Unit 4. The retrofit requirements for this unit were used to establish burner performance criteria. The testing was conducted with nominal full-scale burner designs, having a capacity of 78 million Btu/hr (22.0 MW). Each burner was tested over a wide range of operating conditions and hardware configurations, and with different coals. However, the XCL burner was judged to have the best overall performance and to meet all the Edgewater boiler retrofit requirements. Additional brief tests were conducted to evaluate the impact of burner design on SO2 removal by injected sorbent materials.
