Abstract

ABSTRACT The pursuit of environmentally friendly electricity generation methods, such as the Chemical Looping with Oxygen Uncoupling (CLOU) process, necessitates optimization of both oxygen carrier materials and reactor design. This study focuses on enhancing fuel combustion efficiency and minimizing dust emissions within the CLOU process. A novel fuel reactor design featuring a cascade of return valves is proposed. Computational Fluid Dynamics (CFD) modeling demonstrates that redirecting a portion of the gas flow at angles between 134° and 165° significantly reduces gaseous methane flow velocity, thereby extending contact time and increasing fuel conversion. The design effectively confines submicron and nanoparticles within the reactor, eliminating the need for downstream dust removal. This innovative fuel reactor design offers a highly efficient and environmentally conscious solution for advancing CLOU technology.
