Waste heat recovery
Alfa Laval has the right waste heat recovery solution for any steam need or engine room. Our wide portfolio of economizers, like our holistic approach, is built on 40+ years of waste heat recovery experience. We help you identify the optimal economizer setup, ensuring the greatest energy savings and a future-proof solution for your vessel. Through reduced use of your fired boilers, you can expect immediate and long-term benefit on your bottom line – along with reduced emissions and improved CII.
Take the cost-saving route to lower CO2 emissions
- Maximize vessel energy efficiency with innovative, thermally efficient economizer solutions
- Produce steam by recovering waste heat from main and/or auxiliary engines
- Save on fuel and maintenance by reducing the use of your fired marine boiler
- Reduce your environmental footprint and enhance your CII rating
- Limit your potential exposure to CO2-related taxation and emission trading system costs
Marine waste heat recovery – solutions for today and tomorrow
Alfa Laval has supported maritime industry with thermal solutions for over 100 years. We pioneered marine waste heat recovery, and today’s portfolio reflects our decades of expertise. Whatever your vessel’s challenges, we have a waste heat recovery solution.
Our easily retrofitted, fuel-saving economizers are an ideal way to boost onboard energy efficiency, lower vessel OPEX and improve CII ratings. Our broad range includes:
- Smoke-tube and water-tube economizers
- Single-inlet and dual-inlet solutions
- Compact economizers to minimize installation footprint
That lets us tailor the optimal solution for you – based on your steam requirements, the amount of exhaust gas and your vessel’s unique characteristics. No matter which fuel you use today or tomorrow, you can count on lasting fuel and cost savings through waste heat recovery.
You’ll find similar flexibility in our boiler solutions for methanol and for LNG, and in Alfa Laval’s wider portfolio of technologies for onboard energy efficiency. Our range of energy-efficient solutions is constantly growing, in part through innovation at the Alfa Laval Test & Training Centre.
Waste heat recovery retrofits
Why let any fuel energy go up in smoke? Installing economizers after your auxiliary engines is an easy way to lower fuel costs, reduce emissions and improve CII. Our broad portfolio makes it simple to find an optimized solution, and the fuel you save will quickly pay back your economizer investment – often in less than a year.
From waste heat to electricity
Steam from waste heat recovery can be used by steam consumers, but it can also support clean electrical power. The Alfa Laval E-PowerPack uses Organic Rankine Cycle (ORC) technology, which lets it generate electricity from low-temperature heat sources. By feeding it surplus steam from your economizers as well, you can give power production a significant boost.
