The report describes analyses of a large number of emissions, operating conditions, and boiler configuration data from full-scale, multiple-burner electric utility boilers using natural gas and low-sulfur oil fuels. The report includes: (1) a discussion of the major combustion process modications resulting in NOx emission reductions due to two-stage combustion, burners out-of-service, combustion air temperature reduction, load reduction, and excess air variations; (2) estimates of NOx minima achievable in the boilers studied with current hardware; (3) estimates of most probable longer term hardware and operating condition modifications likely to yield ultimate NOx reductions with these fuels; (4) identification and verification of general mechanisms for the combustion and flame instabilities observed; and (5) a list of all of the hardware configurations, operating conditions, and NOx, CO, O2, and CO2 emissions data for 428 tests in eight full-scale, multiple-burner, face-fired electric utility boilers using natural gas and low-sulfur oil fuels.
