Effects of N2 dilution on laminar burning velocity, combustion characteristics and NOx emissions of rich CH4–air premixed flames

, 2021
Effects of N2 dilution on laminar burning velocity (LBV), adiabatic flame temperature (AFT), intermediate radicals (CH3, H) and NOx emissions (NO, N2O) of methane were investigated using Bunsen burner under the condition of fuel-rich combustion ...

Experimental study and kinetic analysis of the laminar burning velocity of NH3/syngas/air, NH3/CO/air and NH3/H2/air premixed flames at elevated pressures

Combustion and Flame, 2020
Mixing ammonia with syngas can be a promising way to overcome the low reactivity of ammonia, allowing it to find usage in IGCC (Integrated Gasification Combined Cycle) systems and gas turbines for power generation.

The temperature dependence of the laminar burning velocity and superadiabatic flame temperature phenomenon for NH3/air flames

, 2020
Combustion of ammonia (NH3) as a carbon-free alternative fuel has been recently widely studied, with vast majority of the burning velocity data obtained at room temperature.

Measurement of oxy-ammonia laminar burning velocity at normal and elevated temperatures

, 2020
Ammonia is considered as a carbon-free alternative fuel and hydrogen carrier to realize green and renewable energy conversion, but the oxidation mechanism of NH3 still needs to be improved and validated by more experimental data.

Burning velocities of CO flames

Combustion and Flame, 1997
Asymptotic and computational methods are employed to investigate premixed laminar burning velocities of planar adiabatic flames in ideal gas mixtures containing carbon monoxide, oxygen, an inert, and trace amounts of hydrogen-containing species. The chemical-kinetic steps that control the burning velocity are identified, and the dependence of the ...

Theory of Burning Velocity. II. The Square Root Law for Burning Velocity

The Journal of Chemical Physics, 1947
Previous papers by the authors having suggested that the diffusion of active particles (chiefly hydrogen atoms) from the flame front is the controlling factor in combustion in Bunsen-type burners, an equation for burning velocity based on such a concept is derived.
