The Aalborg OL is a large capacity oil-fired steam boiler. It is designed to provide optimal combustion conditions.
Aalborg OL is intended for steam or hot water production, the oil- or gas-fired Aalborg OL (formerly MISSION OL) is supplied as a vertical, two-drum cylindrical boiler.
Its furnace, which is built with membrane walls and contains only little refractory material, is shaped to provide optimal combustion conditions.

Hvordan det virker
Top-fired and available in two different design pressures, the Aalborg OL is a vertical, two-drum cylindrical boiler. Straight tubes connect the water and steam drums directly, which ensures safe circulation with no risk of overheating and subsequent tube burnout.
The furnace is built with membrane walls, which are constructed from gastight polygonal panels that make it resistant to gas pulsations. Containing only a minimum of refractory material, it is shaped to provide optimal combustion conditions. The convection section consists of straight pin tubes with bent pins, which provide a high coefficient of heat transfer and ensure low pressure loss. Circulation is promoted by downcomers placed outside the membrane walls.
Alfa Laval Aalborg steam atomizing burner
The Aalborg KBSD steam atomising burner is designed for use on our top-fired boilers and is delivered pre-mounted. A dynamic wind-box provides for low pressure loss and a stable combustion at low loads. All burner mountings are arranged to ensure easy installation and maintenance.
