Failure analysis of the 150MW gas turbine blades

Autor: J.A. Rodríguez, G. Castillo, G. González, I. Rosales, Jesu´s Nebradt, Gustavo Urquiza, J. Kubiak

Publikováno v: Engineering Failure Analysis. 16:1794-1804

A 150 MW gas turbine experienced a forced break down because of extremely high vibrations and subsequent output power reduction down to almost zero. Before the break down, the turbine was operated by approximately 1800 hours in intermittent mode, wit

Failure of last-stage turbine blades in a geothermal power plant

Autor: F. Z. Sierra, Jesu´s Nebradt, J. G. González, J. C. García, J. Kubiak, V. M. Salinas

Publikováno v: Journal of Failure Analysis and Prevention. 5:26-32

This paper presents an investigation into causes of failure of geothermal steam turbine blades. Several L-0 blades of geothermal steam turbines of 110 MW capacity suffered failures, causing forced outages of the turbines. To assess the causes of fail

Heat Transfer and Thermal Mechanical Stress Distributions in Gas Turbine Blades

Autor: Diganta Narzary, F. Z. Sierra, Je-Chin Han, Candelario Bolaina, Jesu´s Nebradt, J. Kubiak

Publikováno v: Volume 3: Heat Transfer, Parts A and B.

In this paper the distributions of heat transfer and thermal mechanical stress in the metal blade surface are investigated. The stream that surrounds the blade was considered at the time that the cooling airflow runs through the blade interior. Cooli

Influence of Cooling Flow Rate Variation on Gas Turbine Blade Temperature Distributions

Autor: Jesu´s Nebradt, Fernando Cadena, Hugo Lara, Diganta Narzary, Fernando Z. Sierra Espinosa, J. Kubiak, Je-Chin Han, Sarah A. Blake, Areli Uribe Portugal

Publikováno v: Volume 4: Heat Transfer, Parts A and B.

Temperature and flow rate of combustion gases and cooling stream are essential conditions for blade integrity in gas turbines. Since the combustion products pass directly to the first stage of blades high thermal stresses can develop, so the temperat

Integration of Thermal Stress and Lifetime Supervision System of Steam Turbine Rotors

Autor: G Jesu´s Nebradt, P Antonio Carnero, R Lui´s Serrano, M Lui´s Leyva

Publikováno v: Volume 2: Controls, Diagnostics and Instrumentation; Cycle Innovations; Electric Power.

The turbine rotors experience high-thermo mechanical stresses caused by requirements of their operation. These cause mechanical damage (fatigue) that is accumulated according to the frequency with which the different ways of operation (cold, warm or
