Waste Heat Recovery Systems (WHRS)
Pressure Integrity for Energy Optimization
In modern cement plants, energy efficiency is no longer optional, it is strategic. Waste Heat Recovery Systems (WHRS) convert kiln exhaust gases into usable electrical power, directly reducing fuel consumption and carbon intensity.
However, WHRS performance depends heavily on pressure stability and controlled discharge within high-temperature dust-laden zones. Rotary Air Locks play a critical role in maintaining that stability.
Oswar Rotocorp Rotary Air Locks are engineered to preserve pressure integrity and protect energy recovery efficiency in WHRS installations.
What Makes This Zone Demanding
Why Pressure Control Matters in WHRS
- WHRS captures heat from preheater exhaust, clinker cooler exhaust, and kiln vent streams
- Relies on carefully maintained pressure differentials for optimal heat transfer
- Must sustain gas velocity profiles for turbine performance
- Even minor air leakage can reduce system efficiency and power output
- Uncontrolled air ingress lowers gas temperature and reduces heat recovery ROI
Critical WHRS Discharge Zones
- Preheater dust discharge systems under elevated temperatures
- Cyclone separators with abrasive dust conditions
- ESP / Baghouse under WHRS circuits operating continuously
- Clinker cooler dust handling with fluctuating pressure
- Fine material discharge to pneumatic conveying systems
