Pressurized oxy-fuel combustion characteristics of single coal particle in a visualized fluidized bed combustor

Pressurized oxy-fuel combustion (POFC) is recognized as the second generation of oxy-fuel combustion for the reduction of CO2 emissions, which has gradually gained more and more attention recently. In this work, the influence of pressure on the combustion characteristics (i.e., ignition, volatiles combustion, char combustion) of a single lignite particle was investigated in a pressurized visualized fluidized bed combustor under O2/N2 and O2/CO2...
