Comprehensive report to Congress, Clean Coal Technology Program. Full-scale demonstration of low-NO(sub x) cell burner retrofit.

摘要

This project describes the full-scale retrofit demonstration of Low-NO(sub x) Cell (LNC) Burners proposed by the Babcock & Wilcox Company (B&W). The LNC burner was developed by B&W to provide a cost effective means to reduce NO(sub x) emissions in boilers equipped with standard cell burners. The LNC burner is designed to provide an economical replacement for the standard cell burner, reduce NO(sub x) emissions by 50%, and produce no impact on boiler operation and performance. In terms of the reduction of total acid emissions, the expected reduction in NO(sub x), on a tons removed basis, for the LNC burner technology results in the same environmental impact as an equivalent reduction in SO(sub 2) emissions using another technology. The LNC burner fits in existing standard cell burner wall tube openings and therefore, does not require burner relocation or major boiler pressure part modifications. Retrofit materials generally consist of the LNC burner can be retrofitted to all utility boilers containing two-nozzle cell burners and could possibly be adapted to three-nozzle cell burner installations. 6 figs.
