Alfa Laval T2 Gasketed plate heat exchanger

Introduction

Aalborg AV-6N boiler efficiently recovers waste heat from exhaust

gases, making it ideal for steam and/or hot water production. This

boiler is constructed to recover heat from diesel and gas engines,

gas turbines or other heat sources.

The robust and highly efficient water tube boiler significantly

enhances the overall efficiency of power and industrial plants and

reduce the use of fuel, leading to remarkable cost savings and

lower CO2 emissions.

By utilizing heat energy from engine/gas turbine exhaust or

process industry flue gas that would otherwise be released

into the atmosphere, the Aalborg AV-6N contributes to a more

sustainable operation.

Main benefits

• Reduced fuel consumption, leading to remarkable cost

savings and lower CO2 emissions

• Natural circulation: high availability, low operational and

maintenance costs

• Compact heating surface, optimizable for different

applications

• Small water volume inside the boiler allows it to respond

quickly to load changes

• Freedom of scope: shop-assembled, or with maximised

scope for local outsourcing (e.g., insulations, platforms,

inter-connecting pipes etc.)

Boiler design

The boiler’s compact and flexible design, which makes it easy to

install, also allows cleaning during operation, which minimizes

engine shutdowns and increases plant availability.

Designed with extended heating surface, Aalborg AV-6N is

compact and cost-effective. The possibility of cleaning during

operation minimizes the need for engine shutdowns and

increases the overall plant availability.

Natural circulation is used in the standard steam configuration

with resulting advantages for reliability, safety and energy

efficiency, although traditional forced-circulation models are

available if specifically requested.

Unique boiler construction

A unique supporting arrangement without endplates, enhanced

by computerised analyses ensures a vibration and thermal

stress-free boiler structure sustaining even the most demanding

operational conditions of engine-based heat recovery

applications.

Reliable natural circulation

Alfa Laval offers reliable natural circulation solutions as a

standard for steam applications, eliminating the need for

circulation pumps and providing several advantages. These

include enhanced reliability, minimized risk of soot fires, reduced

power consumption, cost effectiveness, fast site installation,

reduced foundation work, minimized piping and cabling, and

a small footprint. Additionally, conventional forced circulation

boilers are also available.

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.
