Overview
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. |
Sample IR Images:
- Boiler Flue Gas Leaks
- Boiler Skin Crack
- Boiler Refractory
- Boiler Economizer
- Boiler Economizer
- Boiler Manway
- Boiler Outlet
- Formation Boiler

1. Boiler Flue Gas Leaks
Maverick scanned for flue gas leaks and to determine the refractory condition. A pre-shutdown infrared survey revealed cracks on the Northwest corner of the boiler on the fifth level. During the shutdown the area was inspected internally and repairs were made as required. Post-shutdown infrared survey confirmed the effectiveness of the repairs.

2. Boiler Skin Crack
This image shows an leak on a boiler in a natural gas fueled power generating station. Close examination showed an vertical, linear indication on the wall of the boiler.

3. Boiler Refractory
This is an image of the wall of an new heat recovery steam generator. Poor refractory is evident around the door, as is a poor seal on the left side.

5. Boiler Economizer
This image shows the end of the economizer section of a large boiler. Poor refractory is evident in the center of this panel. The bright, apparently hot indication to the right is merely loss of the reflective paint.
