Oxy-fuel conversion of sub-bituminous coal particles in fluidized bed and pulverized combustors

• Oxy-fuel combustion in pulverized coal (PC) and fluidizedbed (FB) boilers is being increasingly investigated due toits potential use for carbon dioxide capture. The combustionconditions in the two types of unit differ significantlybecause of fuel size, furnace temperature, and fluid dynamics. These differences affect the change of combustioncharacteristics from air (O2/N2)to oxy-fuel (O2/CO2) conditions in PC and FB in different ways. In this paper, the oxy-fuel combustion behavior of a single sub-bituminouscoal particle in PC is compared with that in FB conditions.The FB data were measured in our bench-scale FB test rig,whereas the PC data were collected from literature. The FB tests were performed at 1088 K with 0%vol
