POSCO chooses Spraystream for large-scale dust control project
POSCO, one of the world's leading steel manufacturers, selected Spraystream to provide a dust suppression solution for its raw material yard in Pohang, South Korea.
The project has been realised in close cooperation with Spraystream's South Korean partner, Handy Co. Ltd, whose local expertise and support have played an important role throughout the implementation process.
A challenging environment for dust control
The coastal yard, measuring approximately 1.4 km in length and 200 m in width, is continuously exposed to strong sea winds. As a result, dust and fine raw materials can be carried beyond the site boundaries. Conventional wind screens were not a practical solution due to the presence of multiple reclaimers operating throughout the yard, making it difficult to install large fixed structures.
A tailor-made hydraulic solution
To tackle this challenge, Spraystream supplied a total of 18 hydraulic dust control units:
- 12 × Spraystream S18.5 Hydraulic Arm
- 6 × Spraystream S15.0 Hydraulic Arm
By generating a fine mist that binds with dust particles, the units prevent the dust to become airborne. The Spraystream S18.5 units provide a throw range of up to 80 metres, while the S15.0 units cover distances of up to 70 metres.
The units were installed on hydraulic lifting arms rather than fixed towers. This configuration offers easier maintenance access, allows the machines to be lowered during severe weather conditions, and reduces the risk of interference with moving reclaimers operating in the yard.
Engineering large-scale dust control
This large-scale dust control installation helps POSCO reduce dust emissions across its raw material storage yard while maintaining uninterrupted operations in a challenging coastal environment.
Due to POSCO's site security and confidentiality policies, photography and video recording on site are not permitted. However, we do have behind-the-scenes footage of the production and preparation process, which offers a closer look at the scale and technical complexity of this project.
