IR – BOILERS
Like furnaces, boilers are an obvious infrared subject since they are a source of a lot of thermal energy. External scans of refractory, piping, and doors are all common infrared applications.
For external surveys, a wide angle lens is often useful for the close views of the skin from the narrow decking. A telephoto lens is useful for images taken from grade or nearby structures.
Safety is also very important when working with boilers. Beware of hot surfaces. Watch for tripping hazards on decking, and make sure you don’t still have your infrared camera in your hand when you climb ladders.
