The Analysis of Geothermal Power Generation by Flash System Combined with Binary Cycle

摘要:

本文通过模拟计算分析得出，对于100℃~150℃的地热资源，利用闪蒸–双工质联合发电系统可以提高发电功率，提高资源的利用率。采用EES软件，分析了闪蒸温度、双工质种类和地热流体流量对该系统发电功率的影响，提出了最佳闪蒸温度的经验公式，结果表明不同工质对于发电功率的影响很大，地热发电功率随地热流体流量的增大而增大。

Abstract: Obtained by simulation analysis of 100˚C - 150˚C geothermal water resources, geothermal power generation by flash system combined with binary cycle can obviously improve the power generation capacity and resource utilization. EES software was introduced to analyze the impact of flash temperature, working fluid and fluid flux for geothermal power generation capacity, and empirical formula for the best flash temperature was proposed. The results indicated that the type of working fluid had great influence on power generation capacity, and geothermal power generation capacity increased as geothermal fluid flow increased.
