Ignition delay times of n-butane and i-butane under O2/CO2 atmospheres: Shock tube experiments and kinetic model

Pressurized oxy-fuel combustion is deemed an advanced oxy-fuel combustion technique due to the lower cost and little decrease in the generating efficiency compared to conventional PC system without CO2 capture. Butane is an important composition of petroleum and natural gas. In this work, the ignition delay times (IDTs) for n-butane and i-butane under O2/CO2 atmospheres were measured in a shock tube at different equivalence ratios (Φ) and …
