Abstract:

While ice formation within the air intake of industrial gas turbines can cause serious damage, fouling (dirtaccumulation)leads to a reduction in output and efficiency. The paper presents the development of a real-time condition monitoring system for automatic detection and qualitative measurement of both ice and fouling. The approach is based on the use of double radon transforms to achieve automatic segmentation of image areas corresponding to inlet guide vanes, and the use of colour information to achieve automatic detection of ice formation and automatic measurement of fouled state. Also presented in the paper are some testing results to demonstrate the effectiveness of the system developed.
