SAACKE Marine Systems

Boilers | Burners | Gas Combustion Units & Automation Technology

SAACKE GmbH is one of the leading manufacturers for BoilersBurners | GCUs | SOx Scrubbers globally with almost a century of experience in firing technology.

The company was founded in 1931 by Carl Saacke as CSÖ and is based in Bremen, Germany with production plants, customer support centers, service stations and sales network worldwide. The company introduced its first burner for marine use to the market in 1934. The company is now a market leader for marine combustion engineering and complete plant systems.

SAACKE on board; this means reliable, environmentally friendly and energy-efficient combustion plants for sea-going vessels, offshore plants and LNG tankers. The vast experience in the development, design and construction of new plants and conversion of existing plants pays off here.

SAACKE offers in-depth expertise and efficient order handling from a single source. Each individual combustion plant not only ensures high availability, but also meets the strictest environmental standards. That holds true for standard configurations and for plants with individual and tailored systems.

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


The GCU combines a burner with an air-cooled steel combustion chamber. All components are built so compactly that the entire system can be accommodated in the area of the funnel and saves valuable installation space in the ship. The GCU has several power-saving blowers, is ignited with either oil or gas and can be run at full load within a few minutes.


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


 The new GCU evo

  • Capacity range: 0.4 – 4.5 t/h methane (other variables available on request)
  • Combustion of the boil-off-gases on the basis of the 100% free-flow-solution
  • Low NOx values thanks to cold flame technology
  • Short flame due to grid burner


 The Classic GCU compact

  • Capacity range 0.5 – 6.5 t/h methane (other variables available on request)
  • Low heat radiation and minimum NOx emission due to the low flame temperature resulting from the high air excess (250%)
  • Turbulent wave motion does not cause contact between the flame and the walls of the combustion chamber. This significantly increases the stability of the combustion chamber
  • Vertical or horizontal installation possible
  • Oil-fired ignition burner guarantees continuous operation even in exceptional situations
  • Controlled fuel-to-air ratio ensures reliable combustion and low emission values
  • Easy maintenance through funnel shaft. Internal parts such as the combustion chamber and burner can be removed and replaced

The SAACKE Multistream Exhaust Gas Cleaning System (EGCS-HM) / SOx scrubber guarantees the continued use of heavy fuel oil, while reliably complying with the required emissions values (reducing Sulphur from 3.5% down to 0.1%). Its short amortization period makes it attractive for new-builds and retrofits alike.


The Scrubber is U-type multi-stream and can accept a combination of exhaust gases from M/E, A/Es and Boilers in a single tower, depending on the requirements of each vessel.


The internally developed EGCS monitor enables the live monitoring of all relevant system data onshore, which offers significant savings potentials for the operator. Overall, the efficient and practical engineering reflects SAACKE’s decades of experience in the field of maritime applications.


  • Capacity range up to 30 MW (engine equivalent)
  • SOx removal rate >99%
  • Modes of operation are Open-Loop, Hybrid or Closed-Loop mode.

In order to maintain the high efficiency of any boiler, the most important operation is routine cleaning, in order to remove carbon and particle deposits from inside the tubes.


You can read more about the importance of boiler tube cleaning in this link.


SAACKE offer 2 solutions for different types of boiler tubes and these cleaning devices are available not only for SAACKE boilers - most boiler types are covered if the respective tube diameter is advised.
a. For Tubular (usually straight) Tubes : Putzmaus - Smoke Tube Cleaner (Automatic)
