| Abstract |
The report describes field studies on utility boilers to develop NOx and other pollutant control technology by modifying combustion operating conditions. Tests were made on 12 pulverized-coal-fired boilers. Six oil-fired boilers, converted from coal-firing, were also tested with combustion modifications for NOx control. Particulate emissions and accelerated furnace corrosion rates were also determined in some cases for coal-fired boilers. Analysis indicated that combustion modifications, chiefly low excess air firing coupled with staged burner patterns, can reduce NOx emissions from the tested coal-fired boilers by 25-60%, depending on the unit and its flexibility. NOx emissions were successfully correlated for normal and modified firing conditions with the percent stoichiometric air supplied to the burners. |
