Abstract
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. Particles diameter demonstrated to have highest impact on the solid flow rate. Particles density and solid inventory in the reactor were affecting the solid flow rate with less impact. Pressure variation loop over the first section of the system was finally presented for three different solid flow rate.
