Abstract
A chemical looping combustion apparatus for solid fuels using different oxygen carriers is provided. The chemical looping combustion apparatus includes: a solid fuel chemical looping combustor configured to receive solid fuels and to produce carbon dioxide and steam by combustion of the solid fuels; a gaseous fuel chemical looping combustor configured to receive gaseous fuels and to produce carbon dioxide and steam by combustion of the gaseous fuels; and a devolatilization reactor configured to produce solids and gases by devolatilizing the solid fuels, and the solid fuels received by the solid fuel chemical looping combustor and the gaseous fuels received by the gaseous fuel chemical looping combustor are the solids and the gases produced by the devolatilization reactor, respectively. Accordingly, a reaction rate and an amount of oxygen transfer can increase, and necessity for low-priced oxygen carriers and a make-up cost of low-priced oxygen carriers can be reduced.
