Abstract |
The document gives results of tests conducted in a 2 MWt experimental furnace to: investigate ways to reduce NOx emissions from utility coal burners without external air ports (i.e., with internal fuel/air staging); and improve the performance of calcium-based sorbents for SO2 control, by modifying the design and operation of the sorbent jets. NOx emissions could be reduced by 50-60% (to 300-500 ppm) without external ports by using two secondary air channels in the burner throat, and by modifying the coal nozzle. A baffle in the outer secondary air channel also appears necessary where high secondary air velocities cannot be avoided. Sorbent testing confirmed that jet design/operation must focus on protecting the sorbent from seeing high peak temperatures: a peak temperature of 1230-1290 C gave optimum sorbent performance. SO2 removals of 80% at Ca/S = 2 were achieved with a pressure-hydrated lime at this temperature. Jet design to increase sorbent heating rate might also have a secondary effect in improving performance. |
