The D-Type industrial watertube 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.

This concept allows English Boiler to custom design each and every unit without incurring extra engineering charges. Any boiler can be changed in height, width, and length without penalizing the customer. Each English boiler is designed to meet and exceed the customer requirements. English boilers usually have more heating surface for the same size and capacity than that provided by other boiler manufacturers.
