摘要：
Thermodynamic analysis of a micro tri-generation system comprising of a solid oxide fuel cell (SOFC), a micro gas turbine (MGT), an organic Rankine cycle (ORC), and heat recovery devices for use as combined generation of cooling, heating and power is investigated in this paper. The mathematical model of the tri-generation system is developed and validated, the input parameters of system under the design condition are exhibited. A parametric study is performed to observe the effects of some key parameters such as the fuel flow rate, fuel utilization factor, steam to carbon ratio and compressor pressure ratio on the evaluation criteria of the system and its components. Results show that under the design conditions the system electricity and exergy efficiency are 69.12%, 64.4% respectively in summer mode while at the same time the overall efficiency of the system can reach 92.65% which is 13.1% higher than that in winter. © All Right Reserved.
