Mechanism Study on N2O Reduced with Biomass Gas

The reduction of N
₂
O by adding biomass gas as reburning fuel is studied on a small-scale vertical reactor tube and experimental results are analyzed using the theory of chemical kinetics. The result showed that for the flue gas containing a certain concentration of N
₂
O, when the biomass gas contained H
₂
, CH
₄
, CO and CO
₂
was used, the reburning fuel ratio should be more than 1.4%. The decomposition of N
₂
O is caused by free radicals, including H and OH in the process.
