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.

Second quarter (25 December 1980-3 April 1981) results under the Advanced Pulverized Coal Combustor f o r Control of NOx Emissions Program (DOE Contract DE-AC22-80PC30296) are reported. The program uses an ideal i zed one-dimensional combustor, incorporating fuel staging. A comprehensive computer model i s being developed under the program to allow NO mechanisms and rates to be extracted from the experimental data. During the quarter, modification of the existing PROF code to include particle effects was begun. Various aspects of the solution procedure are described in t h i s report.
