20110239649 | Steam Characteristics Automatic Measuring Device and Geothermal Power-Generating Device - Provided is a steam characteristics automatic measuring device capable of automatically, ideally also continuously measuring the characteristics of steam taken from a production well, without being affected by interfering components, such as hydrogen sulfide gas and carbon dioxide gas contained in large quantities in steam taken from under the ground, which enables the operator to continuously understand the characteristics of steam and support a smooth operation of a geothermal power plant. The device has a silica monitor for measuring a concentration of silica included in a condensate obtained by cooling steam taken from under the ground; an electrical conductivity meter for automatically measuring the electrical conductivity thereof; a pH meter for automatically measuring the pH value thereof; and a data processing transmitter for automatically transmitting data measured by each of the monitor and meters. A geothermal power-generating device equipped with the steam characteristics automatic measuring device is also provided. | 10-06-2011 |
20110144947 | Online Diagnostic Method and Online Diagnostic System for Geothermal Generation Facility - An online diagnostic system for a geothermal generation facility is discloses that includes: an automatic steam measurement device for measuring a characteristic of steam to be supplied to a steam turbine from a steam-water separator at the geothermal generation facility that outputs analysis data. A monitor•control device controls an operation of the geothermal generation facility while monitoring the geothermal generation facility. A diagnostic device performs at least one of an evaluation of a steam characteristic at the geothermal generation facility, an evaluation of the steam-water separator, and an evaluation of pulsation and confluence of a production well based on the analysis data from the automatic steam measurement device and performance data of the geothermal generation facility from the monitor•control device. An operating status of the geothermal generation facility is diagnosed. | 06-16-2011 |
