Did you know
- The Aalborg XS-TC7A waste heat recovery economizer was introduced by Alfa Laval in December 2012. It was developed as a customized solution to utilize waste heat from auxiliary engines, building on decades of experience with waste heat recovery systems for main engines.
- The XS-TC7A is designed for mid-size and larger auxiliary engines, distinguishing it from the more compact Aalborg Micro, which is intended for smaller auxiliary engines. Unlike the Aalborg XS-2V, which has its own steam space, the XS-TC7A is designed for forced circulation and typically connects to an existing oil-fired boiler for its steam space.
- This model is chosen for its ability to significantly reduce oil consumption for oil-fired boilers by recovering waste heat from auxiliary engines, leading to substantial fuel savings and a rapid return on investment, often within 12 to 18 months. Its compact design, achieved through helix smoke tubes, maximizes heat transfer within a small footprint, making it the smallest smoke-tube economizer on the market.
| Model | Application | Steam Capacity (t/h) | Steam Space | Heating Surface Design |
|---|---|---|---|---|
| XS-TC7A | Auxiliary Engines (mid-size/larger) | 0.1–2.0 | Requires external (e.g., oil-fired boiler) | Helix smoke tubes |
| Aalborg Micro | Auxiliary Engines (smaller) | Unspecified | Requires external (e.g., oil-fired boiler) | Coaxial tubes / Coiled fin tubes |
| Aalborg XS-2V | Main or Auxiliary Engines | 0.5–5.0 | Own steam space | Straight smoke tubes |
