Abstract	New England Power Service Co. (NEPSCo) contracted Riley Stoker to help in evaluating advanced low-NOx, high efficiency oil/gas burners. Baseline pilot-scale tests hav~ been conducted on an 80 x 10^6 Btu/hr burner similar to the 200 x 10 Btu/hr burners currently installed at Salem Harbor Unit 4 and Brayton Point Unit 4. The paper presents the results of the baseline burner pilot-scale combustion tests. Correlation of the baseline burner pilot-scale test results with field test data will be used to evaluate the pilot-scale test performance of the low NOx burners. The paper also presents evaluation criteria used to select burners for atomization testing. An Aerometrics Phase/Doppler particle analyzer was used to characterize atomization quality. A water-glycol solution was used to confirm the effects of viscosity. Based on the results of the atomization tests, two burners have been selected for pilot-scale combustion testing.

OCR Text	Show proposals from the burner manufacturers will be used to evaluate the relative cost of retrofitting each burner to the NEP boilers. PROPOSAL EVALUATION NEPSCo established the following full load performance and operational characteristics for candidate burners: Full Load Performance o NOx emissions less than 0.3 lb/106 Btu for 0.5% wt. nitrogen fuel o Particulate emissions, less than 0.05 lb/106 Btu after the precipitator (precipitator efficiency = 60%) o CO emissions, less than 100 ppm o Flue gas oxygen content, less than 1% by volume (5% excess air) o Carbon in flyash, less than 20% by weight Operational Characteristics o Turndown, 6:1 to 10:1 o Dual fluid atomizer using air or steam o Fuel oil pressure, less than 300 psig at the gun inlet • Ability to fire #6 oil, #2 oil, or natural gas o Fuel oil viscosity at the burner 100 - 150 SSU o Fuel flow: 21 gpm #6 oil, 220 KCFH natural gas AFRC89 5
