| 摘 要： | 采用火用]热力学分析方法，对Shell干粉煤气化系统进行了火用]量衡算，分析了Shell干粉煤气化的火用]效率和火用]损失状况，探讨了提高Shell干粉煤气化系统火用]利用率的措施。结果表明：气化炉是火用]损失最大的设备，占总火用]损失的81．1％；水冷壁火用]效率最低，仅为48．1％；Shell干粉煤气化火用]效率可达77．7％，高于水煤浆气流床气化。Shell干粉煤气化效果较好，高负荷、长运行周期稳定运行是Shell粉煤气化能否成功推广应用的关键因素。

| Abstract: | Through exergy balancing on the Shell coal dust gasification system by means of exergy thermodynamic, analyze the exergy efficiency and exergy losing of this system. Advance some measures to increase the exergy efficiency. The results show that gasifier is the largest exergy loss equipment, amounting to 81.1% of the total loss; the water cooled wall has the lowest exergy efficiency which is 48.1% ; the exergy efficiency of Shell coal dust gasi- fication system is 77.7% which is higher than coal-water slurry entrained flow bed gasification. High load and longterm stable operation determine the Shell coal dust gasification system whether can be successfully used. |
