A 380-kW (1.3 million Btu/hr) two-burner level, tangentially fired, pilot-scale facility was used to characterize a dry-calcium-based sorbent SO2 capture technique combined with an offset auxiliary air low-NOx burner. Baseline tests showed that the facility properly simulates full-scale temperatures and emission levels. Dry sorbent SO2 test results suggest that for enhanced sorbent SO2 capture, injection should take place away from the burner zone where temperatures are lower, and that the time sorbent particles spend in the optimal temperature range should be extended as much as possible through sorbent injection methods and temperature profile modification.
