Abstract

A turbine component (200) includes a first structure (210) and a second structure (212). A first fluid passage (220) is defined in the first structure (210) for delivering a first thermal transfer fluid (222), e.g., a coolant such as air, through at least a portion of the first structure (210) to cool the first structure (210). A second fluid passage (230) is defined within at least a portion of the second structure (212) and is in fluid communication with the first fluid passage (220). After heat transfer in the first structure (210), the heat transfer fluid is hotter than a temperature of the second structure (212), and thus increases the temperature of the second structure (212). The heat transfer to the second structure (212) reduces a temperature difference between the second structure (212) and the first structure (210) that would, without heating, cause thermal stress between the structures (210, 212). The heating of the second structure (212) reduces the need for early maintenance and lengthens the lifespan of the component (200).
