An internal bypass … In 1965 Toshiba manufactured, for the first time, a 22,000 kW turbine- generator for the Matsukawa geothermal power plant in Japan. Since then, we have delivered a large number of geothermal turbines to power plants in the USA, Mexico, the Philippines and Japan. These geothermal turbines have almost all established records in output power, …

HIGH RELIABILITY Toshiba’s geothermal power plant has a high reliability backed by well proven design and abundant field experience. …. 8 DESIGN AND CONSTRUCTION FEATURES OF THE TOSHIBA GEOTHERMAL TURBINE HIGHLY EFFICIENT AND STRONG STEAM PATH The steam path is designed on the basis of massive results of tests and studies and by means of the most advanced computer techniques so that the maximum stage efficiency can be obtained. The impulse type design, in which the diaphragm type nozzles are combined with strong cross section blades, is strong enough against foreign matter. EFFECTIVE SEPARATION OF MOISTURE AND DUST Moisture and dust in the steam path are satisfactorily shaked off by centrifugal force toward the outside wall. The wall is covered with a stainless steel impingement shield to prevent erosion. HIGHLY RELIABLE LONG BLADE SERIES 12Cr steel blades backed up by close calculation and ample experience are adopted. Special care is given to determine blade width and blade tip shroud band construction. STABLE AND LOW-FATT ROTOR The turbine rotor which rotates in erosive steam is made of highly corrosion-proof Cr- Mo-V steel. This rotor is a low-FATT type, which has been used formany high and intermediate-pressure united rotors of fossil fuel turbines
