Alfa Laval

Gas combustion unit

With its simple and reliable construction, the Alfa Laval Gas Combustion Unit (GCU) is the most trusted solution for boil-off gas (BOG) management on LNG carriers (LNGCs) and floating storage regasification units (FSRUs). By combusting the natural gas vapour, it removes surplus BOG that cannot be utilized in the engines or boilers. The proven GCU design, which uses electrical igniters rather than a pilot flame, offers not only dependable safety but also cost-effective and flexible operation.

Safe, reliable BOG management for LNG

  • Choose proven GCU technology that has led the market for well over a decade – delivered to more LNG carriers than any other
  • Match your vessel’s needs with a range of GCU sizes, a flexible fan setup and additional operating options (full free-flow combustion and off-gas mo
  • Maximize peace of mind with stable and even combustion, ignited reliably and without an additional fuel-consuming pilot flame
  • Keep operating costs down with a refractory-free combustion chamber and a low-wear design that minimize maintenance needs
  • Rely on your GCU for many years to come, thanks to optimized airflow that reduces temperature stresses and extends burner lifetime

Regulating LNG cargo tank pressure is crucial to vessel safety, and no choice is more secure than the Alfa Laval GCU. Ours is the original GCU technology, continuously developed with simplicity and reliability in focus Optimized through full-scale testing at the Alfa Laval Test & Training Centre, the GCU 2.0 has an enhanced combustion chamber and burner that increase capacity and lifetime.

The simplicity and easy maintenance are the same in the GCU 2.0, which has a robust design with a limited number of moving parts. Optimized airflow and the elevated burner with electrical igniters create a stable flame in the fully metallic combustion chamber. With design temperatures down to -52°C, the GCU 2.0 is the only solution of its kind for use in Arctic conditions.
