Optimized boiler performance by improving maintenance process, shut-down planning and digital support tools
Jul 26, 2023
Collaboration with Borås Energi & Miljö in Sweden, the cooperation started during the take-over of the plant back in 2019. Through a Performance Agreement Valmet and Borås Energi & Miljö enable stable production by minimizing unforeseen shutdowns.
Summary
| Location | Borås Energi och Miljö, Sobacken, Sweden |
| Challenge |
Enable stable production by minimizing unforeseen shutdowns. Reduce long support lead times which can lead to underperformance of the BFB Boiler. BFB Boiler with steam capacity of 120 MWth ,48 kg/s, 139 bar, 540 °C Fuels: Forest residues, bark, wood chips |
| Solution |
Process optimization, operation support and continuous plant development activities was implemented together with optimization of the maintenance process. The comprehensive 3-year Performance Agreement also included:
|
| Results |
Unplanned downtime was minimized, and overall performance increased through fast and effective support, scheduled maintenance stops, and continuous process development based on performance evaluations and inspections. |
