Abstract | The experimental study is to investigate the control of thermal nitrogen oxides emissions from a 70,000 Btu/hr gas-fired test furnace. Tests, included changing axial or radial air flow rate, adding cooling water, and adding staged air were performed to characterize and optimize the fuel-rich burning zone and the fuel-lean burnout zone independently. Detailed measurements of O2, CO2, CO, NO and NOx were made at the fuel-rich burning zone and furnace exit. The influence of forming CO, NO and NOx was examined. Results indicated that adding staged air in the fuel-rich burning zone (75cm from burner) will reduce the maximum NO and NOx emissions. Adding cooling water in a right position may further lower the NO and NOx emissions. In addition, the least formation of thermal nitrogen oxides in the first stage fuel-rich burning zone will occur at the stoichiometric ratio's inverse value, (o1)^-1, 0.65 to 0.7. |
