摘　　要：燃气轮机循环能用于回收钢厂生产过程中熔渣所产生的余热资源,为了研究余热利用式燃气轮机循环的性能,建立了该循环的经典热力学模型,分析了余热回收温度对循环功率和热回收效率的影响,并以循环功率最大为优化目标,对循环的功率进行了优化,给出了最大功率、最大热回收效率及相应的最佳空气质量流率和最佳压比等经典热力学优化结果。The gas turbine cycle can be used in recovering waste heat of molten slag produced in steel plant. In order to study the performance of this gas turbine cycle for recovering waste heat,this paper establishes a classical thermodynamic model of the gas turbine cycle,and the effects of heat recovery temperature on the power and the heat recovery efficiency are analyzed,and the classical thermodynamic optimization results such as the maximum power,the maximum heat recovery efficiency,the optimal air mass flow rate and the optimal pressure ratio are obtained by taking power as optimization objective.
