Embodiment Construction

[0042] A cylindrical hole of 0.3 mm × 0.3 mm is regularly arranged at an interval of 1 cm to form a grid pattern, which is formed by laser drilling on the MCrAlY coating on the surface of the propeller. A slurry of white fluorescent granular SFP-0010 was prepared in distilled water. Inject the slurry into the small hole with a syringe. Simmer to evaporate the water. Na 2 O·Al 2 o 3 4 SiO2 3 (100g, melting point 1000°C) the adhesive was put into a syringe and melted with a thermal glue sprayer. The melted adhesive is introduced into the small holes in the form of small droplets. Sand off any excess adhesive so the small hole is flush with the surface of the propeller.

[0043] Then put the propeller back into operation. When the surface temperature of the propeller reaches the melting point of the adhesive (1832F), the adhesive melts, releasing fluorescent particles into the exhaust stream. This substance is Image 6 with Figure 7 Device capture shown. Detection an...

Abstract

In this method for forming monitoring deposit on a substrate, a temperature range lower than critical deterioration temperature of the substrate when it is exposed to high temperature in operation is determined, such binder that monitors temperature by releasing indicator in the temperature range determined is selected, the indicator is combined with the binder, and the combination of the indicator and the binder is added to the substrate for forming monitoring deposit. The device includes the substrate and the combination of the indicator and the binder added to the substrate. The binder releases the indicator in the temperature range lower than the critical deterioration temperature of the substrate determined to expose the substrate 16 to high temperature in operation.

Description

Background of the invention [0001] The present invention relates to a method, article and system for monitoring combustion systems with selected binders. Rather, the present invention is directed to an indicator in a selected adhesive. [0002] A gas turbine, including continuous flow mass transfer, one or more compressors, followed by a combustion chamber and high and low pressure turbines are sequentially distributed in an annular outer sleeve along the longitudinal central axis. In operation, the compressor is driven by a turbine to compress air mixed with fuel, which is then ignited in a combustor to produce high temperature combustion gases. Combustion gases flow down through high and low pressure turbines to extract energy to drive compressors to produce output power in the form of shaft power or ram force. [0003] The operating environment within a gas turbine is both thermodynamically and chemically hostile to some turbine components. If the components are located ...
