Alfa Laval TL6 Gasketed plate heat exchanger

Aalborg electric steam boiler

Onboard steam production using shore power or surplus

electricity

The Alfa Laval Aalborg electric steam boiler is a simple, com pact

and combustion-free solution for meeting vessel steam needs.

By utilizing shore power or the electricity already on board, it

delivers steam without producing additional emissions. When

the vessel is connected to the onshore grid, the fired boiler can be

shut down completely, reducing emissions from tank to wake.

Application

As the marine industry decarbonizes, more ports around the

globe are investing in shore power installations. Yet while shore

power provides electricity during a port stay, the vessel’s need for

steam remains. Although fired boilers can generally be used in

port, direct emissions are best kept to a minimum.

With the Aalborg electric steam boiler, vessels can meet the

needs of steam consumers without resorting to combustion.

The boiler can use either the onshore grid or the extra electricity

available on board, such as the surplus on LNG carriers and

FSRUs that comes from using the gensets to manage boil-off

gas (BOG). In both cases, it improves fuel economy and the

vessel’s green profile.

Alfa Laval Industrial line is a wide product range that is used in

virtually all types of industry.

Designed for high throughput, this model delivers excellent

thermal performance. A large selection of plate and gasket types

is available.

Horizontal or vertical installation with excellent vibration

resistance

• Stable output due to relatively large water volume

• Excellent match for HFO heating or applications with low to moderate

steam demands

• Integrated exhaust gas bypass system for capacity modulation

• Valves and instrumentation with a selectable range of automation

• Suitability for district heating via hot water

How it works

Aalborg H/HW boilers are available with vertical or horizontal layouts.

The Aalborg H, which is used for steam generation, has an integrated

steam space and employs natural circulation. The Aalborg HW, which is

used in hot water applications, has flow-optimizing baffle plates and

employs forced circulation.

Both models have a simple and reliable construction comprised of bare

smoke tubes, which are welded to tube plates at both ends of the shell.
