Abstract
The objective of this work, funded by the Physical Sciences Department of GRI and Nordic Gas Technology Centre, is to improve the understanding of the nitrogen chemistry at the final air addition point in reburning and to identify optimum conditions for conversion of reactive nitrogen to N{sub 2} in this region. A parametric study of the burnout zone nitrogen chemistry has been conducted. The effect of temperature, partitioning of HCN, NO and NH{sub 3} in the flue gas, and CO concentration on the conversion of reactive nitrogen has been investigated. Results show that a temperature window exists where both HCN and NH{sub 3} act as reducing agents for NO. At the optimum temperature, significant amounts of intermediate N{sub 2}O is formed. presence of CO and other combustibles moves the temperature window towards lower temperatures. A chemical kinetic model for the nitrogen chemistry has been established. It describes the nitrogen chemistry in the burnout zone of staged combustion. (au) (104 refs.)
