基于Aspen Plus建立喷流床煤气化炉模型

引　言当前 ,环境污染和液体燃料短缺已经成为制约我国经济持续高速和安全发展的瓶颈问题 .通过煤的大规模、综合、清洁、高效利用来解决未来对能源尤其是对液体燃料的需求 ,已经成为我国政府和科学界的共识[1] .在未来的能源结构中 ,以煤气化为基础的新型能源系统无疑将扮演越来越重要的角色[2 ] .因此 ,深入开展以煤气化为基础的新型能源系统尤其是多联产系统的研究十分必要 .鉴于煤气化能源系统中涉及大量横跨动力过程和化工过程的特殊设备 ,本文选择Aspen作为工具软件开展研究 ,其中的一个重要任务就是建立能在Aspen中使用的特殊设备模…

MODELING OF ENTRAINED BED COAL GASIFIERS WITH ASPEN PLUS

Two models that can predict and simulate the performance of entrained bed coal gasifier were established by using the process simulator--Aspen Plus The models are characterized by handling solid materials directly rather than converting them into equivalent conventional components One model uses Aspen built in RGibbs model, and the other uses a user self defined model Both models were verified by the industrial data of three typical entrained bed gasifiers--Texaco, Shell and Destec Finally, the optimal equilibrium temperature ranges of different gasifiers were analyzed and discussed The analysis showed that the optimal equilibrium temperature of slurry feed gasifiers was lower than that of dry coal feed Shell gasifier, and the results of the slurry feed type gasifiers were more sensitive to equilibrium temperature
