Volume I of the report gives details of, and analyzes, trials conducted with natural gas to determine the relationship between combustion aerodynamics and pollution emission characteristics of industrial burners. Three burner types were studied (kiln, ported baffle, and movable vane boiler), based on relative gas load and estimated total industrial emissions. Experimental measurements on a pilot-scale furnace included baseline characterization of each burner and variation of primary operating parameters (air preheat, air/fuel ratio, firing rate, heat release rate, position of gas nozzle in burner block, and air swirl intensity). Additional emissions data were gathered for suspected control conditions (fuel injector design, flue gas recirculation, fuel/air momentum ratio, and burner block angle). It also describes in detail the experimental facility and sampling probes used to collect the data. Volume II discusses completely the procedure used to select the test burners. It includes detailed flame characterizations of baseline operations assembled from in-the-flame temperature, gas species, and flow direction data analysis. Similar in-the-flame studies were made for control conditions which minimized emissions for each burner type. It also includes all raw data collected from the input/output trials.
