Inspecting an industrial chimney: what's the maximum height with an indoor drone?

Inspecting industrial chimneys: a major technical challenge

Industrial chimneys, emblematic structures of industrial installations, play a key role in the evacuation of smoke and gases. Regular inspection is essential to ensure that they function properly, and to prevent risks such as wear, cracks and blockages. However, these inspections are often complex due to their height, difficult access and restrictive indoor conditions. Fortunately, indoor drones such as Multinnov's Stereo2 offer an innovative and effective solution to these challenges. But how high up can they operate?

The specific features of industrial chimneys and their constraints

Industrial chimneys are designed to evacuate large quantities of gas at high temperatures. They can reach impressive heights, up to 300 meters, and often present confined environments that are difficult to explore.

1. Height and structure:

Industrial chimneys vary in size and diameter, which directly influences inspection methods. High heights require equipment capable of reaching the top while remaining stable in cramped environments.

2. Complex environments:

Chimney interiors are often dark, poorly ventilated and full of residues. These conditions pose technical challenges for collecting accurate visual data.

3. Safety constraints:

Traditionally, inspections required human intervention, with high risks for workers. These constraints reinforce the interest in indoor drones.

What is the maximum height an indoor drone can reach for inspection?

One of the key questions when it comes to inspecting an industrial chimney is determining the maximum height an indoor drone can reach. Drones like the Stereo2, which specialize in confined‑space inspections, are designed to fly in complex environments and reach heights of up to 150 meters.

Factors influencing maximum height:

-Signal quality: Drones need to maintain stable communication with the operator. This depends on the power of the transmitter and the drone's ability to avoid interference.

- Autonomy: UAV batteries must provide sufficient flight time for ascent, inspection and return.

- In‑flight stabilization: At great heights, advanced stabilization is essential to capture reliable data.

With the Stereo2, Multinnov guarantees optimum performance even in the most demanding environments, thanks to advanced control and navigation technologies.

Essential technologies for inspection at height

To carry out a successful inspection inside industrial chimneys, drones need to be equipped with specific technologies. Here are the three essential elements for an effective inspection:

1. Stabilization

Stability is paramount, especially in confined environments where walls can create turbulence. Stereo2 's advanced stabilization systems enable the drone to maintain a precise trajectory, even at extreme heights.

2. 4K camera

A high‑resolution camera is crucial for detecting cracks, deformations or obstructions. The Stereo2 is equipped with a 4K camera offering detailed images and in‑depth analysis of inspected surfaces.

3. Powerful LED lighting

As chimney interiors are often plunged into darkness, powerful LED lighting illuminates inspection areas and guarantees usable data.
