Chemical loop combustion apparatus and chemical loop combustion method

摘要

PROBLEM TO BE SOLVED: To provide a chemical loop combustion device capable of suppressing consumption of oxygen carrier particles.SOLUTION: A chemical loop combustion device 100 includes an air reactor 10 forming a first bubble fluidized bed 22 including oxygen carrier particles and air, and oxidizing the oxygen carrier particles by oxygen of the air in the first bubble fluidized bed 22, a riser 12 in which the oxidized oxygen carrier particles are supplied from the air reactor 10 and the oxygen carrier particles are moved vertically upward by a carrier gas, and a fuel reactor 14 in which the oxygen carrier particles are supplied from the riser 12 to form a second bubble fluidized bed 24 including the oxygen carrier particles and a fuel, the oxygen carrier particles are reduced by a fuel in the second bubble fluidized bed 24, and the reduced oxygen carrier particles are supplied to the air reactor 10.SELECTED DRAWING: Figure 1
