| Abstract |
The report gives results of an investigation of combustion modification techniques for controlling NOx emissions that have application to pulverized coal-fired utility boilers. The techniques, studied on a 5 million Btu/hr single-burner pilot unit, included: excess air, air preheat, firing rate, flue gas recirculation, staged, combustion, quench, and swirl. Tests conducted with a Colorado coal showed that NOx reduction of up to 65% were possible by using staged combustion or by lowering excess air levels from 30 to zero %. Flue gas recirculation yielded only moderate NOx reductions for coal. For existing units, control of excess air appears to be the simplest method for NOx reduction. Where possible, staged combustion could be retrofitted on existing units to achieve further NOx reductions. For new units, staged combustion combined with low excess air firing appears to be the most promising method for NOx control. |
