地热电站凝汽器运行压力优选

Optimization of Operating Pressure for the Steam Condenser in a Geothermal Power Plant

摘要: 地热电站热效率低导致单位发电量所产生的凝汽器排热比火电站大得多，这使得凝汽器的运行参数优选对于地热电站的意义与火电站相比更为重要。本文分析了凝汽器运行参数对地热电站性能的影响规律，并基于肯尼亚某地热井机组进口参数，对不同凝汽器运行压力下的机组输出功进行了计算分析，得出了最优的凝汽器运行压力，本研究将为面向地热电站的凝汽器运行压力优选提供科学依据。

Abstract: Due to the relatively low thermal efficiency of geothermal power plant, the steam condenser in a geothermal power plant is more important than that in a fire power plant. This paper analyzed the effect of operating parameters of steam condenser on the performance of a geothermal power plant. Based on the inlet steam parameters of one wellhead power plant located in Kenya, the net output power was computed and analyzed at different condensation pressures, and the optimum operating pressure for the steam condenser was presented. This investigation will provide a scientific base for the selection of optimum operating pressures of the steam condenser in geothermal power plants.
