Features and benefits of the Aalborg D product Standard medium-pressure water tube boiler Two-drum D-type design boiler configuration Horizontal flue gas pass Delivered as complete unit for easy installation Available with pin tubes or bare tubes Designed for operation with a steam atomising burner How it works The Aalborg D boiler is of the well proven two-drum D-type design and is made in standard sizes up to 120 t/h of steam. The Aalborg D boiler consists of a steam and water drum connected by a generating tube bank. The furnace is made of membrane walls forming a fully water-cooled gas-tight furnace. Large unheated external downcomers welded to the drums secure natural water circulation – with a large circulation ratio. Its furnace is built with membrane walls and contains only little refractory material. The convection section consists either of bare tubes or of straight pin tubes with bent pins, which provide a high coefficient of heat transfer and a low pressure loss. Circulation is ensured by downcomers placed outside the membrane walls.
