| 摘 要： | 利用已建立的流化床煤气化模型系统地研究了不同气化方案下的流化床煤气化性能，包括空气气化、空气/蒸气气化、空气/二氧化碳气化、氧气/水蒸气气化、氧气/二氧化碳气化5个气化方案，结果表明：空气/水蒸气和氧气/水蒸气方案具有较优的气化效率和较高的煤气品质，氧气/蒸气气化方案在煤气组分、气化效率和热效率等方面比空气/蒸气气化方案更具优势。

| Abstract: | A series of calculations were carried out to explore the effects of various gasification schemes on the performance of fluidized bed coal gasification using the mathematical model previously established by the authors. The gasification performances for five schemes including air, air/H_2O, air/CO_2, O_2/H_2O and O_2/CO_2 blown were studied. The main results show that the better gasification efficiency and higher syngas quality can be obtained from the schemes of air/H_2O and O_2/H_2O. Furthermore, the O_2/H_2O scheme are more predominant than air/H_2O scheme in syngas composition, gasification efficiency and thermal efficiency. |
