摘要
应用Aspen Plus工业系统流程软件和Gibbs自由能最小化方法对粉煤气流床气化炉进行模拟.在设定粉煤气流床气化炉条件下,研究空气(O2占0.21,N2占0.79)与煤比和气化压力对有效气体(CO+H2)含量的影响.结果表明,在设定粉煤气流床气化炉温度为1500℃和碳转化率为99%的条件下,当煤进料量为3265.87kg/h,空气与煤比为4∶1时,有效气体含量最大.同时,气化压力越大,有效气体含量越大.
The pulverized coal entrained-flow gasifier is simulated by Aspen Plus industrial systems flower software and the minimization method of Gibbs free energy. Under the given conditions of pulverized coal entrained-flow gasifier, the effects of content of effective gas （CO＋ H2） are studied under various ratios of air-coal and various pressures. Under the given conditions of 1 500 ℃ and carbon conversion of 99%, when coal flow volume is 3 265.87 kg/h and the ratio of air/coal is 4 ： 1, the computational results show that the content of effective gas is maximal. At the same time, the content of effective gas increases with the increasing of the pressure.
