Show designed boiler and 40% to 50% for oil firing in a coal designed boiler, without adversely affecting boiler performance. Natural gas reburning with heavy oil as the main fuel yielded NO emissions reductions exceeding x 50% (with maximum reductions approaching 70%) for both oil and gas designed furnace configurations. Heavy (#6) fuel oil reburning with heavy oil as the main fuel was shown to be capable of producing NO emissions x reductions approaching 50% for testing in an oil designed boiler configuration. The test programs described herein represent only a portion the on-going emissions reduction research and development efforts of ABB C-E, ENEL, and FTC. They are part of a continuing effort to bring promising new technologies to market which minimize the cost to benefit ratio without adversely affecting boiler performance. REFERENCES 1.
