Reburning is a combustion modification technique which removes NOₓ from combustion products by using fuel as a reducing agent. Previous studies have shown that natural gas is more effective than coal as a reburning fuel. Objectives of this program are to define the chemical and physical constraints...

Description
Summary:Reburning is a combustion modification technique which removes NOₓ from combustion products by using fuel as a reducing agent. Previous studies have shown that natural gas is more effective than coal as a reburning fuel. Objectives of this program are to define the chemical and physical constraints which prevent the attainment of 80% NOₓ reduction with reburning and to test improved configurations for reburning as an advanced NOₓ control technique for coal-fired boilers. Bench scale studies are designed to screen the chemical and physical means for enhancing reburning efficiency. Pilot studies will evaluate the impacts of finite rate mixing on the effectiveness of the various concepts. The program consists of the following: (1) bench scale studies on N₂ formation in reburning zone and XN conversion in burnout zone; (2) pilot scale studies; (3) interpretation and generalization and a final report. This quarterly report documents the preparation work carried out for the pilot scale studies in this reporting period. 2 figs.
