基于Aspen Plus的化学链燃烧数值模拟

基于Gibbs自由能最小化原理,建立了以贫铁矿为载氧体的化学链燃烧模型,研究了反应物摩尔比、温度及操作压力对反应产物分布的影响。结果表明:反应器温度及反应器压力对化学链燃烧特性有较大影响;适当增加氧碳摩尔比有利于提升反应器出口二氧化碳浓度。

Numerical Simulation of Chemical Chain Combustion Based on Aspen Plus

A model of chemical looping combustion with lean iron ore as oxygen carrier is established based on the principle of Gibbs free energy minimization in this paper.Effect of the ratio of the reactants,temperature and operation pressure on the distribution of the reaction products have been studied.Results show that Reactor temperature and operating pressure has a great influence on chemical chain combustion characteristics,properly increasing the carbon to oxygen molar ratio is beneficial to increase the carbon dioxide concentration at the outlet of the reactor.
