Gas combustion
Gas combustion is crucial in maintaining safe and efficient operations on liquefied natural gas (LNG) carriers. LNG evaporates during transport, and the boil-off gas (BOG) must be managed to prevent overpressure in the cargo tanks. When excess gas cannot be utilized in engines or boilers, a Gas Combustion Unit (GCU) provides a reliable solution by safely burning the surplus. Designed for stability and compliance with emission regulations, Alfa Laval GCU technology ensures seamless LNG transport.
Meeting LNG industry needs with efficient gas combustion solutions
- Simple and compact design without any moving parts inside the combustion chamber
- Combined combustion and dilution fans that do not require silencers or duct pipes
- All-metallic combustion chamber with no refractory lining
- Electric igniters instead of an oil pilot and associated equipment
- Induct burner type that offers a robust and extremely reliable design
Part of a growing LNG portfolio
The Alfa Laval Gas Combustion Unit (GCU) is a central component of boil-off management strategy. It provides a reliable, simple and compact means of safely dealing with excess boil-off gas on LNG carriers with dual-fuel or low-speed dual-fuel engines.
The GCU is joined by inert gas generators, burners, boilers, heat exchangers and more to form an extensive portfolio of Alfa Laval solutions for use with LNG. As fuel choices and cargo needs grow even more specialized, more LNG solutions and other vessel-specific equipment will follow.
Alfa Laval Gas Combustion Unit
The Alfa Laval Gas Combustion Unit (GCU) is a critical unit. It ensures the effective and safe combustion of boil-off gas (BOG), which allows continuous and reliable operations on the LNG carrier.
Innovating at the Alfa Laval Test & Training Centre
At the Alfa Laval Test & Training Centre, the solutions and knowledge for working with LNG on board continue to develop. The facility’s 2800 m2 of testing space include a dedicated LNG process line with a full-size GCU. This unique R&D resource is providing deeper insights into both gas handling and combustion – not only for LNG, but also for other alternative fuels. The efforts will ensure safety and efficiency on tomorrow's more sustainable shipping.
