Why Condensate Recovery Matters
- Condensate contains ~25% of the energy used to produce the steam — recovering it saves fuel
- Every 6°C increase in feedwater temperature saves approximately 1% of boiler fuel
- Returned condensate is chemically treated water — saves water treatment chemical costs
- Reduces makeup water consumption — saves water and sewer charges
- Reduces boiler blowdown (condensate has near-zero TDS) — saves more energy
- Target return rate: 80–90% for a well-managed steam system
