基于化学链制氧的加热炉富氧燃烧系统构建及分析.

Based on the principle of chemical looping oxygen production， the oxy-fuel combustion system of heating furnace was built to solve the oxygen source problem.The feasibility of constructing the system was analyzed by investigating the characteristics of Co3O4 oxygen uncoupling. The results showed that the volume fraction of the equilibrium oxygen from the Co3O4 reduction increases sharply with the reaction temperature. When the temperature is 900℃， the volume fraction of the equilibrium oxygen is 29.6%.The components of CO2 and H2O in flue gas do not affect the oxygen release process of Co3O4. The oxygen volume fraction in flue gas increases with increasing the mole ratio of Co3O4 and flue gas. When the mole ratio is 1:1， the oxygen volume fraction can be up to 24.5% at 950℃. In practice， for a furnace with 32t/h output，when the oxygen-enriched rate is 4%， the Co3O4 filling capacity is 3.4t. [ABSTRACT FROM AUTHOR]
