Heat release rate surrogate for ammonia–hydrogen premixed flames under various conditions
Applications in Energy and Combustion Science, 2023 Blending hydrogen has proven an efficient method to enhance the combustion stability of gaseous ammonia flames. Heat release rate (HRR), as an important parameter to indicate combustion process, is hard to be directly measured and highly dependent on the

Thermal Calculations for Co‐Firing of Hydrogen/Ammonia and Coal in 660‐MW Coal‐Fired Boilers
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT To achieve a clean energy transition under the dual carbon goals, blending hydrogen/ammonia into pulverized coal boilers represents a key technological pathway. Different hydrogen/ammonia co‐firing ratios (5%–50%) are investigated for their impact on the thermodynamic characteristics of 660‐MW supercritical boiler at 100% and 20% boiler ...
