The report describes the analyses of a large quantity of emissions, operating conditions, and boiler configuration data from full-scale, multiple-burner, electric-generating boilers firing coal fuel. Objectives of the study include: (1) evaluation of the effects of combustion modifications on NOx emissions, in fundamental combustion terms; and (2) evaluation of techniques for further reductions in NOx emissions. The report includes the following, pertaining to coal-fired utility boilers: (1) discussion of the major sources of NOx emissions; (2) parametric investigations of the effects on NOx emissions of two-stage combustion, burners out of service, combustion air temperature, and excess air reduction; (3) discussion of probable short- and long-term hardware and operating condition modifications likely to yield further significant reductions in NOx emission in coal-fired boilers; and (4) general comparisons of NOx reduction techniques in utility boilers firing coal, oil, and natural gas fuels. Boiler firing types included single-wall, opposed, and tangential configurations.
