摘　　要：目前利用核电余热供热已成为我国城镇供热系统实现碳中和的重要路径和研究热点。文章研究了核电余热的供热性能;针对发现的供热系统存在余热回收率低、输送距离远等问题,提出了一种基于吸收式换热和反渗透海水淡化技术的水热联产同输系统,并结合案例分析了水热联产同输系统的节能性、环保性和经济性。结果表明:水热联产同输采暖季可节省24.68×10^(4) t标准煤,节能效果显著;采暖季替代燃煤为69.71×10^(4) t,供应淡化水为5712×10^(4) m^(3),环保效益极高;综合供热成本约为37.30元/GJ,低于常规燃煤热电联产供热成本,综合供水成本约为5.03元/m^(3),低于外调水供水成本,其经济性较好。The use of nuclear waste heat for heating has become an important path to realize carbon neutralization in urban heating system and a research hotspot in China.In this paper,the heating performance of nuclear power waste heat is studied,and it is found that there are some problems in the heating system such as low waste heat recovery rate,long transportation distance and so on.In view of the above problems,based on the absorption heat exchange technology and seawater reverse osmosis(SWRO)technology,a type of hydrothermal cogeneration and cotransmission system is proposed.Combined with the case,the energy saving,environmental protection and economy of the system are analyzed.The results show that it can save 24.68×10^(4) t of standard coal in heating seasons,which has a significant energy saving effect.It can replace 69.71×10^(4) t of standard coal and supply 5712×10^(4) t of desalinated water,which has extremely high environmental benefits.The comprehensive heating cost is about 37.30 yuan/GJ,lower than the heating cost of conventional coal-fired cogeneration and the cost of comprehensive water supply is about 5.03 yuan/m^(3),lower than that of transferred water,with a better economicial efficiency.
