Dependence of Biofuel Ignition Chemistry on OH-Initiated Branching Fractions

Frontiers in Mechanical Engineering, 2021
ion of hydrogen by ȮH is the dominant initiation step in low-temperature oxidation of biofuels. Theoretical chemical kinetics calculations for such reactions provide a direct means of quantifying rates of abstraction, which are critical to modeling ...

Global kinetics for n-heptane ignition at high pressures [PDF]

, 1992
A kinetic mechanism of 1011 elementary reactions with 171 chemical species for n-heptane ignition is analysed and reduced to 4 global steps with adjusted rate coefficients to describe ignition at pressures around 40 atm.

Studies of ignition behaviour of biomass particles in a down-fire reactor for improving co-firing performance [PDF]

, 2016
To realize large percentage biomass co-firing with coal in existing coal-fired boilers, the combustion behaviour of biomass is expected to be similar or comparable to that of coal. When co-firing with coal, biomass is not necessarily to be ground as fine
