Steam recovery
Valmet has been a trusted partner in steam separation since the 1980s, bringing extensive experience to optimize energy efficiency in fiberboard and pulping processes. Leveraging this expertise, Valmet offers advanced solutions for recovering steam from the Defibrator system blow line. Our steam separators efficiently separate steam from fibers, enabling reuse in pre-steaming or other low-pressure applications. These solutions help reduce energy consumption, lower emissions, and improve overall process performance.
Reduction in boiler load
Maximum separation at any production level
Reduces total steam consumption in the system
Eliminates the need of fresh steam for pre-steaming
Maximize efficiency with Valmet Steam Separator C
The Valmet Steam Separator C is the smart choice for efficient steam recovery. Designed for simplicity and reliability, it enables the return of up to 30% of the generated steam from the blow line for reuse in pre-steaming or other low-pressure applications. This recovery reduces the need for fresh steam, delivering energy savings and a short return on investment. With no moving parts, minimal maintenance, and easy installation, the Steam Separator C offers a robust and user-friendly solution. By reducing fresh steam demand, it also helps lower VOC and CO₂ emissions, supporting a more sustainable process.
High-performance steam recovery with Valmet Steam Separator PV
For operations demanding maximum energy recovery, the Valmet Steam Separator PV is engineered to deliver. By eliminating the need for fresh steam in pre-steaming and reducing dryer and boiler loads, it can cut total steam consumption by up to 50%. Its advanced centrifugal design ensures efficient fiber separation and stable performance at varying production levels. Built with durable stainless steel components and equipped with vibration dampers for smooth operation, the PV model recovers steam at pressures up to 8 bar, offering significant cost savings and improved process efficiency.
