However, the total efficiency decreases with increasing steam conversion. The negative effect on the efficiency can be offset by rising the temperature of AR. Furthermore, the optimum in the oxygen carrier circulation is found to be 40% excess stoichiometric value and higher than 95% is found to be unacceptable.]]> Wed 11 Apr 2018 11:15:12 AEST ]]> Systematic study of pressure fluctuation in the riser of a dual inter-connected circulating fluidized bed: using single and binary particle species https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:37984 Tue 20 Jul 2021 19:18:32 AEST ]]> Mixing and segregation of binary oxygen carrier mixtures in a cold flow model of a chemical looping combustor https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:20069 Sat 24 Mar 2018 08:00:11 AEDT ]]> Effects of particle cloud extinction on synthesis gas reduction of metal oxides in chemical looping reactors https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:23739 2O₃ metal oxides undergoing synthesis gas (syngas) reduction in chemical looping reactors were theoretically investigated using an adaptation of Semenov’s theory. The extinction was characterised in terms of a critical particle radius and a minimum percentage of the cloud mass loss (%CML). The critical sizes of metal oxide particles in the cloud were found to be strongly affected by the particle size, shape, and reactivity as well as solid volume fraction and type and concentration of the reducing gas. Our analyses indicate that blending of a base metal oxide with another metal oxide species with different reactivity may lower the extinction potential of the cloud (i.e. likelihood of extinction).]]> Sat 24 Mar 2018 07:16:56 AEDT ]]>
