LOW EXCESS AIR HIGH PERFORMANCE MARINE BURNER/COMBUSTION SYSTEM. PHASE II. SMALL SCALE PROTOTYPE TESTS FOR UNITED STATES DEPARTMENT OF COMMERCE,MARITIME ADMINISTRATION
An experimental study was performed on a massive recirculation, 3,000,000 btu/hr, low excess air burner operating in a Cleaver-Brooks Mini-4 boiler. Successful operation was achieved with 1/2 to 1 1/2% excess air and Bacharach smoke ratings of 4 to 6 (zero to trace of smoke visible in stack) while burning No. 6 fuel oil at a temperature of 180F. Recirculation ratios on the order of unity were measured. NOx levels were held to 165 to 220 ppm for the No. 6 fuel oil tested, containing 0.1% fuel bound nitrogen. The apparent turndown capability is at least 5/1 with 11.1 inches w.c. available combustion air pressure difference. No structural problems were noted within the burner. Deposits within the burner were essentially nonexistent. It is recommended that a much larger scale test be undertaken aimed toward marine boiler application for residual fuel combustion. It should result in lower smoke at 1% excess air than found in this small scale test.
