Computational Fluid Dynamic Simulation of a Circulating Dual Fluidized Bed Prototype for Chemical Looping Combustion

摘要

Chemical Looping Combustion is an emerging technology for the "carbon-capture ready" production of energy from fossil fuels. Two chemical looping units have been recently constructed at the National Energy Technology Laboratory to specifically assess and develop this technology: a high-temperature chemical looping reactor and cold flow system with a similar geometry, which is also optically accessible. Preliminary computational fluid dynamic simulations were performed using three different computer codes and compared to the first set of experimental measurements. Additional efforts are needed to refine sub-models to improve predictions and also insure better consistency between simulation platforms.
