Videoscopes can be used to inspect the interior of large gas turbine components such as fuel nozzles. The efficiency and proper working of a gas turbine depends on components such as fuel nozzles to be free of debris and blockage. A small diameter videoscope such as a 4.0 mm diameter will easily access the twists and turns in the tight spaces of these fuel nozzles.
A 4.0 mm videoscope or a small diameter fiberscope will be able to remotely inspect the interior surfaces for foreign objects, residue and blockages that will affect the gas turbine from running at full efficiency. The videoscope should be able to negotiate several 90° bends and twist with the assistance of the scopes articulation.
