MHPS Axial Flow Turbine Direct Contact Condenser, and Recent Projects in Mexico

摘要

In the case of geothermal power generation, the enthalpy of the steam used is lower compared to thermal power generation. The steam is mostly saturated at the inlet to the steam turbine, and the wetness increases at low pressure, therefore increasing the erosion rate. In addition, impurities contained in the steam and the hot water cause scale, precipitation, and corrosion of metal material to all sorts of equipment. Therefore, it is essential for reliable operation to ensure and enhance the performance and reliability of the power generating facilities including steam turbines. In this article, we introduce how we have grappled with the enhancement of performance and reliability for the facilities we have delivered in these past few years.
