Gas combustion

During the last decade, the major part of new-building LNG carriers have changed main propulsion system from steam turbine into Dual Fuel Diesel Electric (DFDE) propulsion. The use of DFDE engines or the new generation 2-stroke DF engines provides LNG ship-owners and operators with economical and environmentally sound alternatives to traditional systems.

Easy to integrate, reliable to operate and easy to maintain

  • 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 ignites instead of an oil pilot and associated equipment
  • Induct burner type that offers a robust and extremely reliable design
The Alfa Laval GCU is considered to offer the smallest footprint on-board and the lowest maintenance cost on the market today. These factors combined with proven technology and simplicity in design makes the Alfa Laval GCU the clear choice for today’s LNG Carriers.

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.

Gas Combustion Unit

Specifically designed for LNG carriers, the Alfa Laval Gas Combustion Unit (GCU) is a reliable, simple and compact means of economically regulating cargo tank pressure on vessels with dual-fuel or low-speed dual-fuel engines.

It safely disposes of boil-off gas when the gas cannot be used by the vessel’s propulsion system, or when it is necessary to prepare the tank for inspection. The unit can also provide backup if the onboard reliquefaction plant should fail. Proven and effective, the GCU requires little maintenance and has a unique design with no perforated dome, refractory lining or expansion joints.
