Product Description

This type of boiler is of double drum, vertical arrangement and “D” type furnace design with 1 or 2 burners located where the front wall stands. Inside it has an air-tight furnace structure with densely arranged tubes and air-proof casing. Outside it is covered with insulation materials and convex color plates. The flue gas takes a U turn.

D type water tube boilers are designed with a large steam drum at the top, vertically connected to a smaller water drum (or "mud drum") at the bottom, via multiple steam-generating tubes which carry feed water (providing the main heat transfer surfaces for the production of steam). These are surrounded by walls made up of larger water-filled tubes, which make up the furnace.

"D" type water tube boilers are designed to reduce overall project cycle time and to lower steam generating equipment costs.

Overview of D type water tube boiler

Boiler structure:
The "D" design boiler is made up of five major components. The components are the Structural Steel Base and Lower Water Drum, the Front Wall, the Rear Wall, and the Upper Steam Drum. These components provide the structural integrity of the boiler. Each component is designed to expand independent of the other components. The membrane wall tubes in conjunction with the corner expansion joints allow for the independent expansion. Regardless of its capacity, each boiler is constructed in much the same manner.
