Steam production and waste heat recovery - 4

Aalborg boilers and burners encompass the best of the efficient features Alfa Laval has developed over the years, along with the latest advances. Yet perhaps their biggest asset is the way they operate in perfect harmony - with each other and with the steam consumers downstream. Meeting steam demands on board is as vital now as it always has been. But today there are new factors impacting why and how this is done. In an era of slow steaming and emission restrictions, the reduction of energy use and environmental impact can be as important as the steam volumes themselves. Alfa Laval is at...

Always in full control Optimized steam production depends not only on the boiler and burner, but also on the control system that steers them. Alfa Laval control ensures safety, fuel efficiency and lower emissions by securing the correct combustion conditions and constantly adjusting the boiler plant to critical parameters. Control at your fingertips Alfa Laval has long been the leader in boiler and burner control. We were the first to introduce self-diagnostic testing for maritime boiler systems, as well as to provide a clear visualization of operating sequences. Today’s Alfa Laval Touch...

The most efficient combustion Optimal combustion is vital to fuel efficiency and economy on board. The right burner, in combination with the right boiler and control, can save fuel and reduce emissions. With well over a half-century of know-how going into them, the burners of our Aalborg range are perfectly matched to the boilers they serve. Burners Aalborg burners from Alfa Laval are designed for reliable ignition and precise combustion. Able to effectively atomize liquid fuels, they maintain a uniform and accurate air-fuel ratio. This ensures ideal heat transfer efficiency and reduces the...

Waste heat recovery As energy efficiency grows even more important, the focus is widening from the production of thermal energy to the reuse of what already exists on board. Already the leader in waste heat recovery, Alfa Laval is expanding both the application and its potential for every vessel. Why let fuel go up in smoke? Partnered for guaranteed savings Only 50% of the fuel energy released by your vessel’s main engine actually goes to propulsion. The rest of it escapes as heat, and it makes sense to reclaim as much of this energy as possible. Alfa Laval boiler technology can recover a...

Utilizing all energy sources At today’s fuel prices, it makes sense to recover heat energy wherever possible – not only from the main engine exhaust. In light of modern engine constructions and slow steaming practices, looking at all exhaust gas sources can actually be a necessity. Auxiliary engine solutions When fuel prices were lower, the waste heat from auxiliary engines seemed less important. But low fuel prices are a thing of the past, and the payback time for auxiliary engine solutions is now less than two years. In some cases today, auxiliary engine waste heat makes a critical...

A systematic approach to energy efficiency A waste heat recovery system is much more than just an exhaust gas boiler. The complete system incorporates the engine, steam turbine and steam consumers – and increasingly a shaft generator. Alfa Laval works closely with all suppliers involved, which is the only way to achieve maximum energy savings. Main engine solutions When we first began adapting our Aalborg boiler technology to waste heat recovery, the main engine was in full focus. This was the natural place to start, given that 50% of the fuel energy released by the engine is turned into...

Recovery solutions for all needs Alfa Laval’s waste heat recovery solutions can improve the energy efficiency of virtually any vessel. Our portfolio stretches from advanced tailor-made systems to simpler plug-and-play solutions, including composite boilers fired with either fuel or exhaust gas. Tailored systems Aalborg OC-TCi Like our traditional boilers, our exhaust gas boilers are generally adapted to the vessel they serve, especially when it comes to main engine waste heat recovery. The more complex the system, the more attention must be paid to sizing, spacing and the configuration of...

Developing the future Our work with steam production has its roots in Aalborg, Denmark, where our first marine boilers were produced. Today Aalborg is still on the cutting edge of development. The Alfa Laval Test & Training Centre Valuable partnerships Boiler technology continues to evolve in Aalborg at the Alfa Laval Test & Training Centre. Here equipment and applications can be tested on the scale of an oceangoing ship – but with the control and convenience that cannot exist at sea. To supplement our own capabilities, Alfa Laval maintains close working relationships with universities,...
