D-type design, in which the steam drum and water drum are connected

by a generating tube bank. The boiler’s furnace, which contains little

refractory, has membrane walls with external downcomers that promote

effective circulation. Delivered as a complete unit, the Aalborg D has a

steam capacity range of 25–120 t/h and a design pressure of 18 bar(g).

Large-capacity fired boiler with proven design

complete units for easy installation

• Configure for oil or gas as fuel, changing no more than the burner

• Produce steam with high efficiency and natural water circulation

Aalborg D is a standard vertical two-drum boiler. The furnace is built of

membrane walls and contains a minimum of refrac tory. The convection

section consists of straight pin tubes with bent pins that provide a high

heat transfer coefficient and low pressure loss. Circulation is ensured by

downcomers arranged outside the furnace.

Capacity range: 25 – 120 t/h
