Study on Combustion Performance and Reaction Mechanisms of Ammonia Blended with Low-Carbon Alkanes

Published: Jan. 1, 2024

Blending co-combustion fuel is an effective strategy for improving the low combustion performance of ammonia (NH3), enabling its use as a power fuel. In this study, impact and underlying reasons types blending ratios low-carbon alkanes (methane ethane, C1/C2) on NH3 were elucidated at level chemical reaction mechanisms efficacy reactive radicals, through experimental numerical simulation approaches. Using dimethyl ether reference to estimate energy efficiency supply. The research indicates that C1/C2 can improve emission levels NH3. enhancement effect more pronounced with C2, particularly when ratio less than or equal 0.5. disparity in effects stems from different chain dehydrogenation reactions number C-H bonds. CH3 radicals generated initial C1 bind H, hindering subsequent reactions. inert C2 appear later, occurring H structure four. However, adverse. leads increase peak concentration NO, but oxidation produces NH NH2, reducing most fuel-NO. This reduction not significant thermal-NO. addition increases intensity N→NO reaction, thereby increasing proportion thermal-NO difficult consume.
