| 摘 要： | 建立了恒温热源内可逆中冷回热布雷顿热电联产装置模型,基于火用分析的观点,用有限时间热力学理论和方法研究了装置的性能,导出了无量纲火用输出率和火用效率的解析式。讨论了总压比给定和总压比变化两种情形,优化了中间压比和总压比,通过数值计算分析了回热度、中冷度和高温侧热源温度与环境温度之比等参数对装置一般性能和最优性能的影响,研究了火用输出率和火用效率之间的关系,其特性关系为扭叶型。最后发现分别存在最佳的用户侧温度使火用输出率和火用效率取得双重最大值。

| Abstract: | An endoreversible intercooled regenerative Brayton cogeneration plant model coupled to constant-temperature heat reservoirs is established.On the basis of the exergetic analysis,the performance of the plant is investigated using finite time thermodynamics.Analytical formulae about dimensionless exergy output rate and exergy efficiency are derived.The two cases with fixed and variable total pressure ratios are discussed,then the intercooling pressure ratios and the total pressure ratios are optimized.The eff... |
