Remove the Burner
The burner assembly is removed after the fuel gas lines have been secured and rendered safe. The arrestor and burner are removed and set to the side. A visual inspection of the inside of the tube is completed. If any issues are found, they are noted and later addressed by the producers. If a heat shield is present, the team will remove the shield to ensure safe working conditions.
Prepare and Clean Fire Tube
The fire tube must be free from debris – such as soot, scale and rust. This is accomplished with specially designed brushes that loosen the material so it can be removed effectively. We use compressed air to facilitate the preparation process. Once the tube has been cleaned, the scanning process can begin.
Inspect and Scan Fire Tube
The scanner head is deployed into the fire tube, starting in the 12 o’clock position. The scanner head is pushed forward, traveling over the steel tube and sending data to the computer. The information is then translated by the software and a digital image is produced. The operator and producer can then determine the depth and location of the corrosion. This process is repeated until the entire fire tube has been scanned. If the tube has significant damage (75%+ or as otherwise instructed), a call is immediately placed to the producer for necessary interventions.
Once the data has been collected and interpreted, the reassembly process begins. If a heat shield was used, it is replaced and re-positioned. The burner assembly is reinstalled and secured to the fire tube flange. If the burner was lit before the disassembly process began, it is then re-lit and the arrestors are placed and secured.
