Simulations of Coal Combustion in a Pressurized Supercritical CO₂ Circulating Fluidized Bed

The supercritical CO2 (S-CO2) power cycle circulating fluidized bed (CFB) integrated with pressurized combustion is a promising power generation technology with high efficiency and low exhaust heat discharge. In multiphase particle-in-cell (MP-PIC) simulations, a 3-D Eulerian–Lagrangian model with a coal combustion process was developed to investigate the combustion characteristics in CFB with S-CO2 wall boundaries under the pressurized...
