Design

Easy to install, the Aalborg OL operates on oils and biofuels and

can also be configured for one alternative fuel: LNG, methanol

or ammonia.* As standard, it is delivered with a preassembled

Aalborg MF SA burner for LNG operation.** The boiler and

burner are both engineered and produced in-house to ensure

the highest reliability.

• Aalborg OL boiler:

The Aalborg OL is a top-fired, two-drum boiler with a

design pressure of 9 or 18 bar(g). Its furnace, which contains

minimal refractory, is shaped to provide optimal combustion

conditions. Membrane walls with gas-tight polygonal panels

make the furnace resistant to gas pulsations.

The boiler’s combustion section comprises straight pin

tubes with bent pins, which provide a high coefficient of heat

transfer and reduce pressure loss. Combustion heat from

the burner is distributed uniformly through the combustion

section, which ensures optimal heat transfer and reduces

damaging thermal stress inside the boiler.

• Aalborg MF SA burner:**

Built with Alfa Laval’s innovative MultiFlame (MF)

concept, the Aalborg MF SA is a steam-atomizing burner

that supports conventional fuels and gas fuels like LNG.

By pre-mixing air and gas, it reduces the production of

CO2. NOx and other emissions.
