GAS COMBUSTION UNITS.

The GCU (Gas Combustion Unit) developed by SAACKE makes the safe transport of liquefied natural gas (LNG) at sea possible. It utilizes excess boil-off gas completely and with maximum availability.

The GCU combines a burner with an air-cooled steel combustion chamber. All components are so compact that the entire system fits in the chimney area, saving valuable space on the ship. The GCU has several energy-saving blowers, can be ignited with either oil or gas, and can be run at full load within a few minutes.

Thanks to its design, which is specially tailored to the specific needs of ships, the GCU combines all the advantages of economical, reliable, and environmentally friendly combustion at sea. This applies to both the GCU compact series and the new SAACKE GCU evo.

GCU evo.

Power range: 0.4 – 4.5 t/h methane

IMO-compliant and class-approved
100% free flow possible
No methane slip
High air surplus ensures low flame temperatures – resulting in low radiant heat and low NOₓ emissions
Operational reliability thanks to the robustness and expertise of our SAACKE team
Rainproof design protects GCU components – especially the burner and combustion chamber floor – from corrosion and wear
No wear on the combustion chamber: Stabilized combustion prevents flame contact with the walls – even in heavy seas
The inner lining of the combustion chamber ensures a cool and therefore stable structure
Controlled fuel/air ratio ensures reliable combustion and low emissions

Productinformation

GCU compact.

Output range: 0.5–6.5 t/h methane

Low heat radiation and minimal NOx emissions due to low flame temperature resulting from high air excess (250%)
No contact between the flame and the walls of the combustion chamber in rough seas, which significantly increases the stability of the combustion chamber
Vertical and horizontal installation possible
Oil-fired pilot burner guarantees continuous operation even in exceptional situations
Safe combustion and low emission values due to controlled fuel-air ratio
Easy maintenance via the chimney shaft: internal parts, such as the combustion chamber and burner, can be removed or replaced
