Gas combustion unit

The Alfa Laval Gas Combustion Unit (GCU) is a reliable and simple technical solution. The Gas Combustion Unit, designed with reliability in mind, serves an important purpose: properly controlling and ensuring the secure disposal of boil-off gas (BOG) that inevitably releases from LNG cargo during its transit route.


The Alfa Laval GCU 2.0 – original simplicity made even smarter

  • Proven, reliable solution built on a long track record
  • Simple design – a perfect balance between compact and safe
  • Extended lifetime thanks to new combustion chamber design and elevated burner
  • Worldwide service and support, available 24/7 and remotely

Alfa Laval solutions are continuously improved, and the trusted Alfa Laval Gas Combustion Unit (GCU) is no exception. 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.


Diverse Sizing of Alfa Laval Gas Combustion Unit (GCU)

Alfa Laval Gas combustion Unit (GCU) is available in multiple sizes and configurations to accommodate the diverse needs of both larger and smaller LNG carriers as well as FSRUs. The choice of GCU size and specifications for LNG carriers and FSRUs depends on a balance between operational needs, safety considerations, space constraints, and regulatory compliance.
