The Influence of Vanes' Cooling Technology on Initial Temperature of Gas Turbine |
| |
| Abstract: | Cooling for the turbine blade is significant to the unit lifetime and work ratio. The increase of the gas turbine work ratio is mostly demonstrated by the increase of the turbine initial temperature. The key to increase the turbine initial temperature is increasing the high-temperature capability of the first and second stage blades, and the main method is researching and developing a high-temperature material and enhancing the blade cooling effects. This essay mainly specifies the impacts of the blade cooling technique on the turbine initial temperature. |
