| 摘 要： | 基于热经济学结构理论,建立太阳能辅助燃煤热发电系统的热经济学成本分析模型,并以C50-8.83/0.294型供热机组和太阳能热利用系统集成取代1段抽汽为例,对系统进行经济性能分析。结果表明,太阳能热量的引入导致太阳能辅助燃煤热发电系统的热经济性能优于单纯燃煤机组,但是由于煤价、集热器价格、年折算运行小时数等因素的综合影响导致系统经济性能较差。最后对热经济学成本进行敏感性分析。以拉萨地区为例,假定煤价上涨幅度和集热器降低幅度均为20%,则当集热器成本下降至480元/m2,同时燃煤价格达1 300元/t时,取代1段抽汽方案的单位热经济学成本与单纯燃煤近似相等,两者可竞争发电。为太阳能辅助燃煤热发电系统的实施提供一定参考。

| Abstract: | Based on the thermo-economics structure theory,thermoecnomic analysis model on hybrid system integrated cogeneration with solar heating system is set up,which is used for economic anlysis of hybrid system.As an example,thermoeconomic analysis on hybrid system integrated a model C50-8.83/0.294 cogeneration with solar heating system is given.The results show that,the thermal performance of hybrid system is higher than the coal-fired only system,but with lower economic efficiency due to the of coal price,colle... |
