Construction

Aalborg OC is a vertical boiler with an exhaust gas section consisting

of bare smoke tubes. The cylindrical shell surrounds

the smoke tubes, the furnace, the steam space and the convective

section, which consists of pin tube elements. The boiler

pressure part is manufactured from mild steel able to withstand

high temperatures. Stress concentrations in corners are minimised

by the simple design of cylindrical shells with flat plates

of equal thickness.

Burner

Aalborg OC is equipped with a Aalborg type pressure-jet burner

or Aalborg types rotary cup burner. The burner is mounted

and can be swung out for service and easy access to inspect

the furnace. The burner housing is mounted on the boiler front,

angled 15 degrees downwards against the furnace bottom. This

allows for a long flame and offers better utilisation of the furnace

and the result is a high performance combustion – even with.

The flow of the combusting particles becomes optimal, and

the result is a high performance combustion – even with the

lowest grades of fuel. As an alternative, Aalborg OC can be

equipped with a rotary cup burner.
