摘　　要：结合循环流化床锅炉构建了一套油页岩固体热载体综合利用系统,以锅炉产生的高温循环灰为油页岩干馏提供热量,并集成燃气-蒸气联合循环和常规蒸气轮机发电机组实现油-电联产。利用Aspen Plus软件对所构建的系统进行建模,结合公朗头矿区油页岩样品的物性数据,计算系统的物流参数和发电功率,并探讨了循环灰温度和油页岩干馏比例对系统的影响。结果表明,提高循环灰温度将降低系统的灰岩比,同时有利于提高系统的发电功率,但系统总发电效率会有所下降;增大油页岩干馏比例能提高页岩油的产能,系统能效呈上升趋势,同时也增加了燃气-蒸气联合循环机组的发电功率,但系统总发电功率却急剧下降。An oil shale comprehensive utilization system integrated a CFB boiler was constructed,in which the circulating ash was used as solid carrier to provide enough heat for retorting,additionally,a combined cycle system and a conventional steam turbine were integrated for power generation.The simulation process of the system was built by Aspen Plus software with the physical parameters in the model coming from Gonglangtou mine′s oil shale sample,and the effects of the circulating ash′s temperature and the oil shale′s mass fraction for retorting on the system were analyzed.The results showed that rise of circulating ash′s temperature could reduce the mass ratio of ash to shale and increase the total power of the system with power generation efficiency reduction.Furthermore,increase of the oil shale′s mass fraction for retorting could improve the shale oil production and the power of combining cycle system,meanwhile,could increase total energy efficiency,but the total power output of the system was reduced simultaneously.
