On line Chimney inspection camera

PCR have perfected the requirement of inspecting industrial chimneys lining whilst the Chimney is on line.

The benefit of this equipment allows Maintenance Engineers to survey their Chimneys without having to plan for a turnaround or shutdown. 

During our developement of the camera we had to consider the following:- 

  • Extreme heat within the Chimney up to 300 degrees c
  • Danger to personel working at the top of the Chimney due to heat and noxious gases


The hazards were fully considered and an engineer proposal developed as follows;

The lining would be filmed with a self contained system within a heat capsule.

The equipment consisted of 4 videos recording onto SD cards, the capsule would also house powerful lighting to enhance imagery.

The camera would be delivered to the top of the Chimney by a 10m long telescopic davit that allowed the workforce to be approx 5m from the top of the chimney at all times.

Once the camera was winched to the top of the davit this davit would be swung into the centre of the chimney and the camera lowered into the internal brickwork lining system.  For a typical survey the camera can be lowered, raised and withdrawn from the Chimney within 30 minutes.
