Returkraft：对垃圾焚烧发电锅炉进行无脚手架超声波测厚检查
挪威垃圾焚烧发电厂 Returkraft 使用搭载超声测厚（UT）设备的无人机测量锅炉管壁厚度。制造商报告称，UT 作业从最多300小时降至约8小时，无需脚手架，停机时间缩短约48小时。在狭窄弯曲的管子上调整探头角度较为困难，且需要预先清洁。
| 业主 | Returkraft (waste-to-energy plant) |
| 服务商 | — |
| 地点 | Kristiansand, Norway |
| 机型 | Flyability Elios 3 with UT payload |
| 传感器 | ultrasonic thickness (UT) probe, 4K video, LiDAR |
引入前
10–15 名脚手架工花费约 1,700 小时在锅炉内搭设脚手架，随后无损检测人员花费约 300 小时进行 UT 测厚。
引入无人机后
电厂自有团队使用带 UT 探头的无人机采集管壁厚度读数，无需进入锅炉。
成果
| 指标 | 数值 | 依据 |
|---|---|---|
| UT inspection time | about 8 hours (incl. battery changes) vs up to 300 hours | 报告值 |
| measurements | over 150 UT readings in 2.5 hours of flight | 报告值 |
| outage length | about 48 hours shorter; 7 days of scaffolding avoided | 报告值 |
| cost | €450,000 stated as saved | 报告值 |
注意事项与局限
- Manufacturer case study (Flyability); the €450,000 figure is presented both as the saving and as the cost of the traditional method, so it is internally inconsistent.
- Curved narrow tubes (44.5 mm and 57 mm) required careful probe angling; the boiler cleaning system must run first and fouling may need removing.
- An earlier FPV drone could not fly the space and gave only visual data.
- Year not stated in the article; city (Kristiansand) is from the plant's public identity, not the article.
