Chimney Inspection

PCR have perfected the requirement of inspecting the chimney lining whilst the Chimney is on line and also use drones to conduct initial external inspections where applicable.

A ‘Hot Camera’ has been designed and used on a number of jobs where the Client is unable to switch off the boilers on an industrial chimney due to operational reasons.  The benefit of this equipment allows maintenance engineers to survey their chimneys without having to plan for a turnaround or shutdown.

  • During our development of the camera we had to consider the extreme heat within the industrial chimneys up to 300 degrees C
  • Danger to personnel working at the top of the Chimney due to heat and noxious gases

The hazards are fully considered and an engineered proposal has been developed as follows:-

The lining is filmed with a self contained system within a heat capsule, the equipment consists of 4 videos at 90 degree points recording onto SD cards; the capsule  also houses powerful lighting to enhance imagery.

To keep up to date with the ever increasing changes in technology PCR have purchased and trained personnel in the use of operating UAV type Drone’s  to access chimneys, flare stacks, bridges and viaducts.

This allows for a more cost-effective means of assessing any potential defect to a structure and can be used to ascertain the true nature through video and photographs in order to plan accordingly for a planned shutdown.
