This invention includes a detection system that can determine if a turbine component, such as a turbine vane or blade, has exceeded a critical temperature, such as a melting point, along any point along the entire surface of the vane or blade. This system can be employed in a conventional combustion turbine having a compressor, a combustor and a turbine section. Included within this system is a chemical coating disposed along the entire interior surface of a vane or blade and a closed loop cooling system that circulates a coolant through the interior of the vane or blade. If the temperature of the vane or blade exceeds a critical temperature, the chemical coating will be expelled from the vane or blade into the coolant. Since while traversing the closed loop cooling system the coolant passes through a detector, the presence of the chemical coating in the coolant will be sensed by the system. If the chemical coating is detected, this indicates that the vane or blade has exceeded a critical temperature.

[ I claim:] [1.] A detection system that detects whether a turbine component has reached a critical temperature at any point on a surface of the component, comprising:a chemical coating disposed on an interior of the component that is adapted to be expelled from the component, in the form of a particulate if the component reaches a temperature that is approximately equal to the critical temperature. [16.] A method of detecting whether a turbine component has reached a critical temperature at any point on a surface of the component, comprising:cooling the component by exposing an interior of the component to a cooling medium; andpassing the cooling medium through a detector that determines if a chemical in the form of a particulate that forms at about the critical temperature is present in the cooling medium. The method of claim 16, wherein the chemical comprises a chemical coating applied along the interior surface of the component. The method of claim 16, further comprising the step of injecting the chemical into the cooling medium before the step of passing. The method of claim 16, wherein the chemical comprises adamantyl imide.
