为了合理地建立热电厂的热储系统,需要探究该热储系统的储能效果以及对环境的影响情况.文章以吉林省桦甸市热电厂为例,构建该研究区的地下水-热耦合模型,并设计了最佳储热模型,对该热电厂热储系统的储能效果进行定量分析,还分析了该热储系统对研究区环境的影响情况.研究结果表明:两口热水井的总提热量为2.2×1011 J/d;热储系统对环境的影响需要15 a以上才能够达到稳定状态;人工热储系统可以节约标煤4400 t,可以减少CO2排放量10967 t.%Studying on the energy storage effect and environmental impacts of the thermal storage system in thermal power plant is of great importance in establishing reasonable thermal storage system. A groundwater-thermal coupling model was proposed in Huadian city, Jilin province. Then, a best thermal storage model was designed to analyze the energy storage effect of the thermal storage system in thermal power plant quantitatively, as well as the effect on environment. The results showed that the total heat of the two hot water pumping and injection wells was 2.2 ×1011 J/d. More than 15 years were needed to reach the steady state on environment. 4400 tons of standard coal can be saved and 10967 tons of carbon dioxide can be cut using artificial heat storage. These results have important implications for protecting the environment.
