Ammonia blending with ethanol offers a promising solution for carbon-free fuel with enhanced combustion properties. A detailed combustion chemical kinetic mechanism was developed for NH3/C2H5OH blends, validated extensively against experimental data for accuracy. The study explored laminar burning velocity, ignition delay time, and the effect of ethanol on combustion properties under various conditions. A modified formula showed a strong correlation with LBVs of blended fuels. Additionally, the research investigated NO and N2O behaviors, noting that higher NH3 cracking ratios reduce NO generation. Ammonia and ethanol blends show potential for efficient combustion with reduced emissions, contributing to the shift towards renewable energy sources.
