摘　　要：为了满足日益增长的低碳供热需求,同时提升供热系统的运行灵活性和经济效益,本文提出了一个集成“燕龙”池式低温供热堆(DHR-400)、储热水池、燃气锅炉的核能供热系统(DHGHS)。以辽源市某一集中供热区域作为DHGHS的应用场景,开展了以费用年值最小化为目标的设备容量配置与运行优化,并与DHR-400+储热水池、DHR-400+燃气锅炉、燃气锅炉、地源热泵等4种供热方案进行了对比分析。研究结果表明:额定容积为3.15×10^(5)m^(3)的储热水池和额定容量为82.79 MW的燃气锅炉可以实现DHGHS在整个供热期的灵活运行,DHR-400的功率调节次数仅有177次。DHGHS的最优费用年值为1.16×10^(8)元,低于其他4种供热方案,最佳供热规模为1.18×10^(7)m^(2)。本文工作可为多热源DHGHS的设计及运行优化提供理论指导。In order to meet the growing demand for low-carbon heating and improve the operational flexibility and economic benefits of the heating system,a nuclear heating system(DHGHS)integrating a"Yanlong"pool-type low-temperature heating reactor(DHR-400),a heat storage pool,and a gas boiler was proposed.A central heating region in Liaoyuan City was taken as the application scenario of DHGHS,the equipment capacity and operation optimization with the goal of minimizing the annual cost were carried out.A comparison between DHGHS and four heating schemes including DHR-400 and heat storage pool,DHR-400 and gas boiler,gas boiler,and ground source heat pump was conducted.The results show that the heat storage pool with a rated volume of 3.15×10^(5)m^(3)and the gas boiler with a rated capacity of 82.79 MW can achieve the flexible operation of DHGHS throughout the heating period.The total number of power adjustments of DHR-400 in the whole heating period is only 177 times.The optimal annual cost of DHGHS is RMB 1.16×10^(8),which is lower than the other four heating schemes.The optimal heating scale of DHGHS is 1.18×10^(7)m^(2).The work in this paper can provide theoretical guidance for the design and operation optimization of the multi-heat source nuclear heating system.
