The Aalborg 3-Pass Mini boiler is a gas, LFO or dual fuel industrial boiler with

a 0.5-2.5 ton/hour steam capacity and a design pressure up to 21 barg.

Having a capacity of 0.35-1.90 MW, the Aalborg 3-Pass Mini may be used for

a hot water application as well. This very compact boiler comes as a complete

skid-mounted unit – ready to be installed. Designed and optimised with the

total of Alfa Laval’s technical and innovative competencies in every detail

– inside out.

Pressure parts

The heating surfaces are arranged symmetrically with the furnace in the

centreline of the boiler to secure optimum water circulation. The reversal

chamber is water cooled in order to reduce the refractory to a minimum

and to ensure an optimum noise reduction. The pressure part builds on

well documented design and production concepts. All pressure

parts are manufactured carefully in selected materials with high tensile

steel. The Aalborg 3-Pass Mini boiler is designed according to the EN 12953

or ASME sect. I standards.

Control/security system

The control system/security system incorporates:

• Burner Management System with load and sequence control with starting

sequence/safety interlocks and load control.

• Water level control and safety.

• Motor starter.

Burner

The Aalborg 3-Pass Mini comes with a Monobloc burner which may be used

for gas and LFO or a combination hereof (dual fuel).
