A Mechanical Property, Non-Destructive Testing and Microstructural Investigation of Power Plant Mechanical Systems

Coal or lignite thermal power stations are built next to the lignite mines and they are usually vast technological installations with a multitude of mechanical parts that need to be maintained and tested for life assessment. These include the excavating equipment, the ore crushers and belt conveyors, the furnace with its steam generating tubes and super heater coils, a steam drum and a steam turbine. Most of these are made of steel and other metal alloys and often fail due to normal service wear, bad maintenance, human error and poor material quality.
