Oxy-fuel conversion of sub-bituminous coal particles in fluidized bed and pulverized combustors
Journal article, 2017
Oxy-fuel combustion in pulverized coal (PC) and fluidized
bed (FB) boilers is being increasingly investigated due to
its potential use for carbon dioxide capture. The combustion
conditions in the two types of unit differ significantly
because of fuel size, furnace temperature, and fluid dynamics. These differences affect the change of combustion
characteristics 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-bituminous
coal 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
