基于流程模拟的固体氧化物燃料电池-燃气轮机-有机朗肯循环联合系统的优化分析
Optimization Analysis of the Solid Oxide Fuel Cell-Gas Turbine-Organic Rankine Cycle Combined System Based on Process Modeling
摘要
Abstract
The organic Rankine cycle (ORC) coupled as bottoming cycle with solid oxide fuel cells (SOFC) and gas turbines (GT) can fully recover the waste heat from the topping cycle system for power generation,thereby improve the energy conversion efficiency of the entire combined system.In this study,we developed an integrated model with numerical analysis for a SOFC-GT-ORC combined power system.A comprehensive parametric analysis is conducted to predict the effect of system performance to the variations in design and operating parameters such as the fuel and air flow rates of SOFC,the pressure ratios of turbine and compressor,the flow separation fraction of the ORC cycle,etc..The optimal criteria for several key parameters are also given,which will in turn provide theoretical guidance and reference for the optimal design and operation of SOFC-GT-ORC and similar combined power systems.关键词
