摘要
分析闪蒸分离发电系统的热力过程。基于肯尼亚Olkaria地区某典型地热井测井参数,计算得出地热电站输出功率、热效率和火用效率随井口热流体参数的变化规律。经计算,获得比功最大条件下的最优汽水分离器压力。当汽水分离器工作温度等于地热流体闪蒸点温度与凝汽器运行温度的算术平均值时,系统比功最大,地热电站输出功率也最大。
The thermodynamic process of flash separation power generation system is analyzed. The variation rules of output power, thermal efficiency and exergy efficiency of the geothermal power plant with wellhead thermal fluid parameters are obtained based on the test data of a typical geothermal well at Olkaria area, Kenya. The optimum pressure of steam-water separator at the maximum specific power was achieved by calculation. When the working temperature of steam-water separator is equal to the arithmetic average of the geothermal fluid flash temperature and the condenser operating temperature, the specific power of the system is the maximum, and the power output of geo- thermal power plant is also the maximum.
