“…However, combustion of neat ammonia still has drawbacks such as low flame speed, sensitivity to nitrogen oxide formation, and difficulty in controlling ammonia slip . Blending with highly reactive fuels such as CH 4 , , H 2 , syngas, , and methanol , can significantly improve the flame speed of ammonia combustion and control ammonia slip. In addition, blending with fossil fuels such as CH 4 and coal , can also reduce CO 2 emissions.…”

The evaluation and reduction of kinetic models for the cofiring of NH 3 and CH 4 can help to guide the application of NH 3 and CH 4 in industrial equipment. In this work, eight detailed kinetic models on the cofiring of NH 3 and CH 4 and 15 detailed kinetic models on the NH 3 combustion are collected and evaluated based on error function and experiment measurement, and the detailed mechanism of 169 species and 1268 elementary reactions with the best overall performance was determined. By using two mechanism reduction methods of directed relation graph with error propagation (DRGEP) and DRGEP with sensitivity analysis (DRGEPSA), the skeletal mechanism of 45 species and 344 elementary reactions is achieved within the temperatures of 1000–2000 K, pressures of 1–60 atm, and equivalence ratios of 0.5–2.0. The skeletal mechanism is comprehensively validated and achieves good consistency with the detailed mechanism in predicting the laminar burning velocity, species concentration, and ignition delay time. The maximum relative error between the skeletal mechanism and the detailed mechanism is less than 13%.
