本文提出了中温太阳能与二甲醚－氧化钴化学链燃烧整合的新颖冷热电联产系统，并对系统热力性能及关键参数对系统热力性能的影响进行了分析。研究表明，燃气透平入口初温（TIT）1000℃，压比8．8时，新系统的总能效高达92．6％。在输出量相同的情况下，新系统的化石能源节能率达29．3％，太阳能集热面积节省率可达69．8％。同时，采用热重分析仪对系统关键过程－二甲醚－氧化钻化学链燃烧开展了初步的实验研究，验证了新系统的可行性。
In this paper, a novel solar-hybrid trigeneration system with chemical looping combustion （CLC） has been proposed, and the system is analyzed to evaluate its thermodynamic performance, examine the effect of its key parameters. As a result, the thermal efficiency of this system is expected to be 92.6%. In addition, the FESR of the new system can be as high as 29.3% and the SASR is expected to reach 69.8% at a turbine inlet temperature （TIT） of 1000℃ and the pressure ratio of 8.8, respectively. Meanwhile, experiments on the key process-dimethyl ether-fueled CLC are conducted in a TGA apparatus to prove the feasibility of the proposed system.
