The Alfa Laval Aalborg Micro is a uniquely compact

water-tube economizer. Easy to install, operate and

maintain, it reduces the use of the fired boiler by

recovering heat energy that otherwise would be

lost through the engine exhaust gas. This ensures

a rapid return on investment.

Despite its minimal footprint, height and weight,

the Aalborg Micro has an extended heating surface

created by coiled fin tubes. Even more efficient than

smoke-tube economizers, it provides an ideal retro

fit solution where no other economizer will fit.

Application

Only a portion of the fuel energy released by marine engines

actually goes to propulsion. A large amount of it escapes

as heat, and it makes sense to reclaim as much of this en

ergy as possible. This is true for auxiliary engines as well as

main engines.

Steam produced with the Aalborg Micro can support or fulfil

steam needs in port, but it can also serve other functions.

For vessels whose long-stroke main engines produce

cooler exhaust, it can provide a needed steam boost during

a voyage. If there is no steam shortage while sailing, the

additional steam produced with the Aalborg Micro can

be used to generate electricity, for example by means of

Organic Rankine Cycle (ORC) technology.
