In order to explore the low-carbon and environmentally friendly thermal power generation technology and improve the utilization efficiency of clean energy, a power generation system consisting of Allam cycle and clean heat sources is proposed. The thermodynamic models of the main equipment in the system are established, the advantages and principles of the coupled system are explained by comparing with the reference system, and the influence of the design parameters on the system performance is studied through parametric analysis. The calculation results show that the low-grade clean heat source can effectively solve the heat imbalance problem of the Allam regenerator, thereby heating the recycling stream to a higher temperature. Under typical design parameters, the exergy efficiency of the coupled system can reach 54.07%, which is 4.01% higher than that of the reference system. The output power and exergy efficiency of the coupling system first increase and then decrease with the increment of the turbine inlet temperature. With the increase of the temperature and the mass flow rate of the clean heat source, the output power of the coupled system increases, while the exergy efficiency first increases and then decreases. The research results of this paper can provide data support and theoretical support for low-carbon power generation technology.

为了探索低碳环保的火力发电技术,提高清洁能源利用效率,提出一种耦合清洁热源的Allam循环发电系统。建立了系统中主要设备的热力学模型,通过与参考系统的对比阐释耦合系统的优势及原理,并通过参数分析研究设计参数对耦合系统性能的影响机制。计算结果表明:低品位的清洁热源可以有效解决Allam循环回热器的热量不平衡问题,将循环工质加热到更高的温度,进而提高系统性能。在典型算例下,清洁热源耦合系统的㶲效率可达54.07%,比参考系统高4.01百分点;耦合系统输出功率和㶲效率随透平进口温度的升高先升高后降低;随着清洁热源温度和流量的增加,耦合系统输出功率有所增加,㶲效率先升高后降低。研究成果可以为低碳发电技术提供数据支持和理论支撑。

为了探索低碳环保的火力发电技术,提高清洁能源利用效率,提出一种耦合清洁热源的Allam循环发电系统。建立了系统中主要设备的热力学模型,通过与参考系统的对比阐释耦合系统的优势及原理,并通过参数分析研究设计参数对耦合系统性能的影响机制。计算结果表明:低品位的清洁热源可以有效解决Allam循环回热器的热量不平衡问题,将循环工质加热到更高的温度,进而提高系统性能。在典型算例下,清洁热源耦合系统的㶲效率可达54.07%,比参考系统高4.01百分点;耦合系统输出功率和㶲效率随透平进口温度的升高先升高后降低;随着清洁热源温度和流量的增加,耦合系统输出功率有所增加,㶲效率先升高后降低。研究成果可以为低碳发电技术提供数据支持和理论支撑。

In order to explore the low-carbon and environmentally friendly thermal power generation technology and improve the utilization efficiency of clean energy, a power generation system consisting of Allam cycle and clean heat sources is proposed. The thermodynamic models of the main equipment in the system are established, the advantages and principles of the coupled system are explained by comparing with the reference system, and the influence of the design parameters on the system performance is studied through parametric analysis. The calculation results show that the low-grade clean heat source can effectively solve the heat imbalance problem of the Allam regenerator, thereby heating the recycling stream to a higher temperature. Under typical design parameters, the exergy efficiency of the coupled system can reach 54.07%, which is 4.01% higher than that of the reference system. The output power and exergy efficiency of the coupling system first increase and then decrease with the increment of the turbine inlet temperature. With the increase of the temperature and the mass flow rate of the clean heat source, the output power of the coupled system increases, while the exergy efficiency first increases and then decreases. The research results of this paper can provide data support and theoretical support for low-carbon power generation technology.
