摘要：

Lean combustion takes the advantage of low NO emission levels, but it faces flame instability. Clean combustion with both low NO emissions and stable flames can be achieved by adding electrolysis products of water to n-decane combustion in the air. The addition of water electrolysis products extends the extinction limit by enhancing the OH+H2=H+H2O reaction and H+O2=O+OH reaction. In the mean time, the indices of NO emission increased by the ratio of water electrolysis products via the pathway of N+NO=N2+O reaction and N+OH=NO+H reaction. Clean combustion with super-stability flame can be achieved by adding a proper amount of water electrolysis products (equivalence ratio Φ=0.5 and addition ratio of water electrolysis products RWEP=0.3) to decrease the extinction residence time at the fuel-lean condition with a suitable NO emission index. Our numerical study shown the clean combustion of n-decane fuel and our research will be of great significance to diminution of carbon oxides in atmosphere globally. © 2022, Politechnica University of Bucharest.
