Ammonia Co-Firing for Coal Fired Power Plant (CFPP) Boiler
As the world transitions toward cleaner energy solutions, non-carbon fuel combustion is emerging as a key technology to reduce greenhouse gas emissions. Ammonia co-firing in coal-fired power plant (CFPP) boilers offers a promising pathway to decarbonize existing power infrastructure. By partially replacing coal with ammonia, a carbon-free fuel, power plants can significantly cut CO₂ emissions while maintaining stable electricity generation.
Our research focuses on optimizing ammonia combustion in CFPP boilers to ensure efficiency, safety, and minimal environmental impact. We investigate combustion characteristics, NOₓ emission control, and the integration of ammonia co-firing with existing plant operations. Through advanced modeling and thermodynamic analysis, we aim to develop scalable solutions that accelerate the transition to low-carbon energy systems while utilizing current power plant assets effectively.

CFD Analysis of NH₃ and H₂ Combustion
Ammonia (NH₃) and hydrogen (H₂) are promising non-carbon fuels for cleaner energy applications, but their complex combustion characteristics require in-depth analysis to ensure efficiency and stability. Computational Fluid Dynamics (CFD) provides a powerful tool for understanding turbulent combustion, especially in cases involving partially cracked ammonia, where NH₃ is converted into H₂ and nitrogen before burning. By utilizing advanced simulation methods such as Large Eddy Simulation (LES) and Reynolds-Averaged Navier-Stokes (RANS), we can accurately capture turbulence-chemistry interactions, pollutant formation, and flame propagation dynamics.
Our research focuses on improving the predictability and accuracy of CFD models for NH₃/H₂ combustion, addressing key challenges such as flame instability, NOₓ emissions, and ignition characteristics. Through high-fidelity simulations, we analyze how different operating conditions, fuel compositions, and turbulence scales impact combustion performance. This approach helps in optimizing burner designs and combustion strategies that maximize efficiency while minimizing harmful emissions.
By integrating experimental validation with numerical modeling, we aim to develop reliable combustion frameworks that support the transition to ammonia and hydrogen-based energy systems. Our findings contribute to advancing cleaner combustion technologies, ensuring that NH₃ and H₂ can be safely and effectively utilized in power generation, industrial heating, and other energy-intensive applications.

Combustion Experiments in Co-Flow Burner
Experimental analysis is crucial for understanding the combustion characteristics of ammonia (NH₃) and hydrogen (H₂) as alternative fuels. In our research, we conduct combustion experiments using a lab-scale co-flow burner equipped with precise flow controllers, high-resolution sensors, and advanced diagnostic tools. This setup allows us to systematically investigate flame behavior, including stability, propagation, and pollutant formation under various operating conditions.
By analyzing key parameters such as temperature distribution, flame speed, and emission levels, we aim to gain deeper insights into the fundamental combustion processes of NH₃ and H₂. Our experiments focus on the effects of fuel composition, flow dynamics, and turbulence on flame structure and efficiency. This data serves as a foundation for validating numerical simulations and optimizing combustion models. Through a combination of experimental measurements and theoretical analysis, our research contributes to the development of more efficient ammonia-hydrogen combustion technologies.
