Abstract: The combustion chemistry of formaldehyde in fuel-rich flames has been studied by numerical modeling and sensitivity analysis. It has been shown that the wide flammability limits of CH$_2$O air mixtures are due to features of the combustion chemistry of formaldehyde at high equivalence ratios rather than to the superadiabatic temperature effect. In this case, the thermal decomposition reaction of hydrogen peroxide H$_2$O$_2$ plays a key role in the conventional branching reactions.

Keywords: formaldehyde, flame speed, combustion chemistry, numerical modeling.
