Alfa Laval Aalborg OL dual-fuel central heating boiler in Alfa Laval Test as well as Training Center
Alfa Laval is playing a vital function in delivery’s step in the direction of LNG propulsion. Its modern technologies as well as knowledge– specifically in the location of central heating boilers– are making it possible for vessels take care of boil-off gas (BOG), an important action in making the change to LNG.
Alfa Laval’s dual-fuel central heating boilers, Gas Combustion Unit (GCU) as well as solutions create a total profile of services for BOG security.
HANDLING BOIL-OFF GAS
To utilize LNG as gas, vessels have to have the ability to take care of boil-off gas (BOG), the vaporized gas that can enhance storage tank stress. Alfa Laval’s Gas Combustion Unit (GCU) securely burns BOG in conformity with the International code for Gas as Cargo (IGC). When it involves utilizing LNG for propulsion under the International code for Gas as Fuel (IGF), Alfa Laval is additionally handling BOG with dual-fuel Alfa Laval Aalborg central heating boilers– tipping the equilibrium in LNG’s support for a much bigger variety of vessels.
When an LNG gas storage tank is included right into a vessel, the stress developed by BOG has to be maintained a degree that prevents air flow to ambience using the security shutoff. Reliquefaction of the gas is feasible, yet doing this aboard includes substantial intricacy as well as expense for the majority of vessels. Likewise, melting the gas in supporting engines or gensets calls for pressurization, which requires a repetitive pricey compression train.
“On some vessels you can use a Type C tank to allow pressure to accumulate,” states” states Markus Tauriainen, Manager Exhaust & & Combustion System Sales atAlfa Laval “But what most vessels need is a safe solution for burning off the gas at low pressure. That can be a GCU on LNG carriers, but the best and most economical solution for vessels using LNG as fuel is usually a dual-fuel boiler.”

A central heating boiler, either for generating heavy steam or for home heating thermal oil or water, is tools that vessels require anyhow. Since an Aalborg dual-fuel central heating boiler can be terminated with LNG, it can handle the extra security feature of BOG monitoring. “Boilers are a compact, simple and highly affordable way to handle boil-off gas,” Tauriainen states. “As strange as it may sound, our Aalborg dual-fuel boilers have been the enabler for LNG propulsion in many, many projects.”
MORE INTELLIGENT PREPARATIONS FOR LNG STORAGE TANK EXAMINATION
Aalborg central heating boilers, like the GCU, have yet one more benefit when it involves BOG monitoring. Every 5th year, when a vessel gets in completely dry dock for examination, the storage tank atmosphere have to be made non-hazardous by changing the LNG with inert gas. During this procedure, Aalborg dual-fuel central heating boilers can melting the combination of inert gas as well as LNG.
“Inert gas itself doesn’t burn, so the mixture resulting from the inerting process can’t be fed to an engine or genset,” statesTauriainen “It can be fed to an Aalborg dual-fuel boiler, however. So the boiler offers a time-saving and economical solution to this recurring issue, which otherwise has to be solved by visiting an onshore disposal terminal before and after dry docking.”
Alfa Laval has actually provided, enhanced as well as sustained central heating boilers for 100 years, as well as has actually marketed over 100 Aalborg dual-fuel central heating boiler systems to day. That experience is coupled with BOG expertise from the GCU, plus R&D muscle mass at the Alfa Laval Test & & Training Center in Aalborg, Denmark, a 1350 sq. m center with a specialized wing for gas as well as burning services.
“Our Aalborg dual-fuel solutions are designed with boil-off gas in mind and are influenced by our experience with the GCU,” statesTauriainen “The boiler uses LNG efficiently for heating, but by managing the boil-off gas and making LNG propulsion possible, it also enables far greater savings. GCU or boiler, steam or thermal fluid – we have a solution to make LNG propulsion happen, on any size or type of vessel.”
COMPLETE SUPPORT
As a full-scope provider, Alfa Laval offers not just internal design as well as production, yet additionally comfort with appointing as well as a reputable worldwide solution network.
“Responsiveness is crucial in safety applications,” statesTauriainen “We’ve spent decades building up our boiler services, and we can meet vessels at their next port in the vast majority of cases. In an emergency, we also have field service engineers who can be dispatched to sea.”
Bringing Alfa Laval solution knowledge closer than ever before: an expanding variety of electronic solutions. Alfa Laval BOG services all utilize Alfa Laval Touch Control, a next-generation control option with a user friendly touchscreen user interface. As well as supplying teams with usual controls for all BOG-related tools, Alfa Laval Touch Control supplies a system for data-driven upkeep as well as optimization.
“Customers today want immediate solutions for converting to LNG propulsion,” statesTauriainen “They’ll find them at Alfa Laval. But we’ll also support customers as time goes on, so that they can achieve greater savings and peace of mind over their solution’s lifetime.”
