2 near marine CONTINUED STORY FOR “BOILER INNOVATION – INSIDE AND OUT” “A boiler is more than a giant kettle, even if what it produces is steam or hot water,” says Lars Skytte Jørgensen, Vice President Product Centre Boilers. “There’s deceptive complexity in the tubes and internal configurations. Constantly optimizing the heating surfaces and the flow of media through the boiler has been the key to reliability and efficiency.” Over the years, Aalborg boiler innovations have saved fuel by increasing the thermal output from every square millimetre of heating surface. But advances have also been made by seeing the boiler as a part of a wider system. The best example is waste heat recovery, which today provides steam, electrical power and even energy for propulsion. “When we pioneered it in the 1960s, we couldn’t have imagined the importance of waste heat recovery today,” Jørgensen says. “Back then, heating boiler surfaces with exhaust gas was a novelty. Today, it’s an integral part of saving fuel in an era of energy efficiency.” Multi-fuel Aalborg boiler at the Alfa Laval Test & Training Centre A higher level of control Steel is only a small part of Alfa Laval Aalborg boiler solutions. Effective control ensures safety, fuel efficiency and lower emissions by securing ideal combustion conditions and adjusting the systems as needed. Alfa Laval Aalborg boiler solutions were the first to provide self-diagnostic testing and a clear visualization of operating sequences. But today’s Alfa Laval Touch Control brings boiler control to a completely standard. The graphical touchscreen display and intuitive navigation make it easy for crews to secure efficient boiler operation, giving them a complete plant overview and access to any data or function in only two touches of the screen. “Retrofitting Alfa Laval Touch Control is a simple process of just five steps,” says With its robust PLC-based design, Alfa Stig Person, Vice President Aalborg Service. Laval Touch Control offers future-proof “The new generation of boiler control can expansion possibilities. But just as help customers get the best from their boiler importantly, it can easily be retrofitted to systems – whatever generation those happen boiler systems that already exist. to be.” The answers to burning needs As the marine fuel landscape changes, so do the demands placed on boiler combustion. Alfa Laval Aalborg boiler solutions are giving customers the flexibility and reliability they seek. The burner is just as important as the boiler in a fired boiler system, where changes in one impact the other. “We optimize our burners for reliable ignition and precise combustion,” says Lars Skytte Jørgensen, Vice President Product Centre Boilers. “But we also fine-tune them to match the specific boiler configuration.” Today that process involves a whole range of fuels. With many vessels running on gas and other alternatives, Alfa Laval Aalborg multi-fuel burners are providing flexibility as well as efficiency and fuel economy. “Multi-fuel solutions are a key focus of our work at the Alfa Laval Test & Training Centre,” says Jørgensen. The 1350 m2 facility in Aalborg, Denmark, has performed extensive tests and flame analyses using different fuels to secure ideal combustion with the full range of alternatives. “Whether customers work with gas, synthetic fuels or traditional HFO, they can expect top combustion performance.” 1950 After World War II, Aalborg marine boilers are supplied to an increasing number of international shipyards and ship owners. 1960s The number of boilers going to European shipyards increases. During this decade, the unique combined oil and exhaust gas boiler is designed and introduced to the market. 1982 The first large waste heat recovery (WHR) plant after a turbo generator is delivered. Over the years, the largest WHR plants for the largest container ships in the world will follow. 1988 The KB oil- and gas-fired burners are added to the product range through the acquisition of Dansk Fyrings Teknik A/S, based in Odense, Denmark. 1994 The Sunrod Group, with its portfolio of marine boilers, exhaust gas economizers and marine boiler service, is acquired from ABB.
