Chemical looping combustion furnace and chemical looping combustion system

摘要

PROBLEM TO BE SOLVED: To improve operational reliability by simplifying the facility structure while preventing upsizing of equipment in a CLC system burning the solid fuel.SOLUTION: A CLC furnace comprises: an oxidation chamber; a reduction chamber; a fluid bed; a circulation part; a single furnace body having a partition wall partitioning an upper space of the oxidation chamber and an upper space in the reduction chamber, and a partition wall having a lower end disposed in the fluid bed that are formed inside. In the oxidation chamber, oxidizing oxygen carrier particles while the particles are flowing with oxidizing first supply gas. In the reduction chamber, mixing with solid fuels to burn the solid fuels and reduce oxygen carrier particles while the particles are flowing with non-oxidizing second supply gas. The circulation part includes: a first channel for allowing oxygen carrier particles oxidized in the oxidation chamber with the first supply gas to flow to the reduction chamber ; and a second channel for allowing oxygen carrier particles reduced in the reduction chamber with the second supply gas to flow to the oxidation chamber.SELECTED DRAWING: Figure 1
