The 13th International Conference on Fluidization - New Paradigm in Fluidization Engineering
Experimental results from a cold flow unit of a novel chemical looping combustion configuration are presented in this paper. The system employs a non-mechanical lvalve to control solid flow rate and uses loop-seals to minimize gas leakage. A model was developed to predict solid flow rate and pressure variation in different elements of the system. The developed model was able to well predict solid flow rate within an error range of 10% for a wide solid flux range of 70 – 150 kg/m².s. Sensibility of the solid flow rate was analyzed for different operating parameters by aid of the model. …

The 13th International Conference on Fluidization - New Paradigm in Fluidization Engineering
In the present work the system of interconnected fluidized bed reactors of a Chemical Looping Combustion (CLC) process is simulated in pilot plant scale and 100 MWth scale. Attrition models, derived from small scale laboratory experiments, are employed to predict the behavior of a large scale CLC process in terms of attrition and oxygen carrier (OC) losses. Realistic circulation mass flows of OC are calculated and the sources of the losses are further investigated. Different arrangements of cyclones are evaluated for their potential to improve the solids recovery. For example the introduction of a second-stage cyclone separation for the air …
