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

“…After passing the compressor and gaining higher pressure, the air with high density and temperature participates in the furnace combustion, thus intensifying the combustion process. The enhancement of combustion increases the volume heat load of the furnace, and the heating surfaces absorb more heat to reduce exhuast heat loss and in turn increase the system efficiency. − Sun et al designed a pressurized fluidized bed combustion (PFBC) system for S-CO 2 recompression cycle and found that the increase of pressure decreased flue gas heat discharged to the environment, raising the power generation efficiency. Besides this, the pressurized combustion has other advantages such as strengthening the reaction intensity, increasing the carbon conversion, reducing the equipment volume, and saving the construction cost.…”
