Infrared thermal imaging is a non-intrusive thermal technique that detects transient disparities and provides surface temperatures by way of capturing the radiation energy from the body. Application of this technique in the ESP portion of a power plant has provided extensive data for pioneering design modifications. The purpose of hopper heater modules provided on ESP hopper surface is to avoid clinker formation in the ash being collected at the bottom of ESP. Excessive power intake of the heater elements leads to higher auxiliary power consumption of ESP and has a bearing on the entire power plant operation. The issue of high auxiliary power consumption is resolved by the application of thermal imaging. Extensive data is collected for lucidity and an unambiguous conclusion.
