The overall objectives of the full-Scale Low-NO{sub x} Cell{trademark} Burner (LNCB{trademark}) Retrofit project is to demonstrate the cost-effective reduction of NO{sub x} generated by a large, base-loaded (70% capacity factor or greater), coal-fired utility boiler. Specific objectives include: (1) At least 50% NO{sub x} reduction over standard two-nozzle cell burners, without degradation of boiler performance or life; (2) Acquire and evaluate emission and boiler performance data before and after the retrofit to determine NO{sub x} reduction and impact on overall boiler performance; (3) Demonstrate that the LNCB{trademark} retrofits are the most cost-effective alternative to emerging, or commercially- available NO{sub x} control technology for units equipped with cell burners. The focus of this demonstration is to determine maximum NO{sub x} reduction capabilities without adversely impacting plant performance, operation and maintenance. In particular, the prototype evaluations will resolve many technical issues not possible to address fully in the previous pilot-scale work and the single full-scale burner installation.
