Project summary description:
Fluidised-bed technology is suggested as a means for utility-scale NH3 combustion which, owing to its thermal stability and fuel flexibility, is hypothesised to achieve stable and high-intensity NH3 combustion as well as potentially low NOx emission.
A fixed-bed reactor may be considered a special case of fluidised-bed where the reduced gas flowrate yields a lower upflow velocity in the reactor, thereby allowing the bed particles to settle into resting positions. This is particularly relevant for industrial scale power generation applications where, in cases of low load operation, flowrate through the reactor is decreased and thus the influence of bed material on flame formation and combustion in a fixed-bed system becomes of interest.
A fixed-bed reactor, more fundamentally, functions as a research tool to study reaction behaviour in the presence of solid bed material. This will provide foundational information to aid in the development of an in-depth understanding of fluidised-bed NH3 combustion which exhibits a more complicated reaction environment. Prior to fixed-and-fluidised bed experiments, however, a detailed set of flow reactor NH3 dissociation and oxidation experiments is required to establish a baseline to which subsequent data may be compared.
