Alfa Laval Aalborg Mini 3-Passv

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).

Easy installation

The boiler is mounted on a skid - ready to be plugged in. Supplied with ready

-mounted burner, control panel, fittings and cables.

Compact design

The small foot-print makes the boiler easy to install.

Easy inspection and maintenance

All boiler connections/valves and inspection doors are located in such manner

that they easily allow access for access for operation and maintenance.

Easy to clean

The smoke tubes are fast and easy to clean thanks to the low number of spiral

tubes. Uniform, high steam quality The boiler is designed with symmetric drawing,

with stable and uniform evaporation and suitable steam space ensuring a high

saturated steam quality Improved combustion The furnace design in conjunction

with the burner ensures an efficient combustion and low atmospheric emissions.

Accessories

The Aalborg 3-Pass Mini comes with pressure part with insulation, Monobloc

burner, feed water pump, on/off/ water level control, steam outlet, blow down

and safety valves as well as control panel as standard. As optional extras, you

may be supplied with a stand-by feed water pump, automatic blow-down valves,

sample cooler, stack, feed water tank, blow-down tank, chemical dosing system

as well feed water treatment equipment.
