Inspection of chimney and flue ducts at Danish incinerator

In this case study, we explain how we used drones to find damage in the chimney and flue gas ducts at a Danish incineration plant.

Key points from the case:

We easily fly into vertical channels that were previously difficult to inspect.

Our drone is equipped with a safety grid and full LED lighting.

Deliver data as an interactive inspection report with 3D model.

Chimney inspection with a drone

When inspecting the chimney, which has a significant height, we identified a damp area with visible water ingress at a height of 50 meters. This indicated a possible leak or condensation issue that could lead to corrosion and structural damage over time.

Inspection of the flue ducts with a drone

In one of the vertical flue ducts, we found blisters in the fiberglass. This is a sign of material degradation, which can reduce the life of the duct and may require repair or replacement to prevent further damage.

The benefits of drone inspection

The use of our drone for this inspection brought several significant benefits:

Safety: No need for scaffolding or rope climbing, minimizing risk to employees.
Efficiency: The entire inspection was completed quickly and without disrupting operations.
Detailed documentation: 4K video and LiDAR scanning provided an accurate assessment of the damage, which helped the customer plan necessary maintenance work.

Conclusion

This case highlights how drone inspection can reveal hidden damage in a fast, safe and cost-effective way. The customer gained valuable insight into the condition of the facility and was able to plan preventive maintenance, potentially saving significant costs in the long run.
