High-pressure biomass steam
Thermax Steam-aaS enables reliable, low-carbon process heating in the aluminium industry

Project overview
A large aluminium manufacturing facility required uninterrupted, high-temperature process heating to support its energy-intensive operations. With round-the-clock production and zero tolerance for instability, the site needed to transition away from furnace oil while preserving uptime, reliability, and process control.
Thermax partnered with the plant to design and operate a biomass-based steam solution aligned with its long-term decarbonisation roadmap.
Challenges
- At this scale of operation, even a short fuel interruption can translate directly into production losses. The facility needed complete confidence in year-round fuel availability, with no room for stock-outs or performance swings. Managing large daily fuel volumes introduced additional concerns around dust, hygiene, compliance, and waste handling. The transition to biomass had to deliver the same predictability as furnace oil—without adding operational risk or complexity.
Solution
- TOESL, implemented a high pressure steam configuration operating at 67 kg/cm² with governed biomass as the primary utility input.
- Multi-fuel flexibility using wood chips, briquettes, CNS, and other loose biomass
- Planned daily fuel offtake management with strict quality gates
- Controlled fuel-mix governance to manage large-scale daily consumption
- A disposal ecosystem designed for high volumes and compliant handling
- Disciplined operating routines engineered for 24 X 365 continuity
- This integrated operating model ensured predictable steam delivery while enabling a reliable transition to biomass-based energy at scale.
