Power Generation Industry Use Cases for Indoor Drones: An Overview of Assets and Applications
Curious about how drones are being utilized indoors in the power generation sector? Here’s a deeper look into their applications.
The primary function of these drones is to gather visual data remotely during internal inspections. Below, we’ll explore various use cases for indoor drones in this industry, including:
- Key applications of indoor drones in power generation facilities
- Real-world case studies showcasing drone usage in power plants
### Key Applications of Indoor Drones in Power Generation
Indoor drones are proving invaluable across numerous assets within power generation facilities. Inspectors rely on them to examine everything from boilers to wind turbines, ensuring safe and efficient operations. Here are some examples of where drones are making a difference:
#### Coal-Fired Boilers
When inspecting coal-fired boilers, drones help assess the condition of burners, refractory materials, and superheater piping within the combustion chamber. They also detect clogs and signs of wear and tear in air pre-heaters, all while minimizing human exposure to hazardous environments.
#### Heat Recovery Steam Generators (HRSG)
During outages at combined-cycle plants, drones are employed to evaluate the structural integrity of supporting pins, burners, and lancers inside HRSG units. This allows maintenance teams to identify potential issues without interrupting critical power generation processes.
#### Wind Turbines
Drone inspections of wind turbine blades have become standard practice during planned shutdowns. Additionally, drones provide access to otherwise hard-to-reach areas like the pillars and basements of operational turbines, offering comprehensive assessments without halting production.
#### Pulp and Paper Mill Recovery Boilers
For recovery boilers, drones visually inspect refractory materials, burners, tubes, and pipes within the combustion chamber. These inspections occur both during scheduled maintenance windows and emergency shutdowns, enabling timely repairs and preventing costly downtime.
#### Asset Commissioning
Before new installations go live, drones perform pre-commissioning inspections of critical components such as coal-fired boilers. This ensures construction quality meets specifications and reduces the risk of future failures.
#### Nuclear Power Plants
In highly regulated environments like nuclear facilities, drones offer a safe alternative for assessing equipment integrity in radioactive zones. By eliminating direct human exposure to radiation, drones enhance worker safety while maintaining operational standards.
#### Waste Incinerators
Similar to other combustion systems, waste incinerators benefit from drone inspections. Visual checks of refractory materials, burners, tubes, and pipes help maintain optimal performance and prevent accidents.
#### Hydroelectric Power Plants
Hydroelectric facilities utilize drones to capture images of confined spaces like surge tanks, water canals, penstocks, and flood gates. This data aids engineers in monitoring structural health and addressing any anomalies promptly.
#### Transformers
High-voltage transformers require regular monitoring for liquid levels and leak detection. Drones equipped with thermal imaging capabilities make these tasks easier and safer by accessing otherwise inaccessible areas.
#### Chimneys / Smokestacks
General visual inspections of chimneys using drones help detect cracks or other defects. This proactive approach prevents catastrophic failures and extends the lifespan of these vital structures.
### Case Studies Highlighting Drone Usage in Power Generation
To better understand the impact of indoor drones, let’s dive into real-world examples:
- **Offshore Wind Turbine Inspection**: A leading power company, Ørsted, tested the Elios 2 drone for inspecting wind turbine blades. The results were impressive—inspecting 40% more of the blade area, cutting inspection times in half, and improving overall safety.
- **Scrubber Inspection Efficiency**: TVA conducted trials with the Elios 2 to inspect a scrubber unit. The drone reduced inspection times by 98%, saving nearly 470 hours of labor compared to traditional methods.
- **Boiler Inspection Savings**: Pampa EnergÃa, Argentina’s largest independent energy provider, saved $420,000 during initial tests of the Elios 1 before upgrading to the Elios 2. Their investment underscores the long-term cost benefits drones bring.
- **Chimney Safety Improvements**: DTEK, a Ukrainian energy firm, successfully deployed the Elios 2 for chimney inspections. The drone collected necessary data faster and kept personnel away from dangerous heights, demonstrating its value in hazardous conditions.
These stories highlight just how transformative indoor drones are becoming in the power generation field. As technology continues to evolve, expect even greater efficiency gains and safety improvements across industries relying on complex infrastructure.
