Abstract

This study examines the co-firing characteristics of a zero-carbon fuel based on methane gas (CH₄) with hydrogen (H₂) and ammonia (NH₃) by means of numerical simulation using ANSYS CHEMKIN-Pro and the performance analysis tool Ebsilon. Four different co-firing conditions are analyzed, namely, pure H₂, pure NH₃, 100% NH₃ full cracking fuel (75% H₂ + 25% N₂), and partial (60%) NH₃ cracking fuels. Adhering to identical adiabatic flame temperature values across all co-firing conditions, we maintain the same TIT (Turbine Inlet Temperature) for calculation purposes. Notably, a slight increase in NH₃ fuel composition leads to elevated fuel NO_x, presenting an obstacle in applying premixed-type gas turbine combustion. Cycle analysis results demonstrate that power output and efficiency increase as the blending ratio is raised, with significant disparities among the blending fuels.
