Watertube Boilers

Indeck Watertube Boilers

Watertube boilers are industrial boilers that produce steam or hot water for various applications. Unlike firetube boilers, which have hot gases passing through the tubes and water surrounding them, watertube boilers have water circulating inside the tubes while hot gases pass around them. This design allows for higher efficiency and faster steam generation in large-scale industrial settings. Watertube boilers work by transferring heat from combustion to the water-filled tubes, converting it into steam or hot water for use in processes such as power generation or heating systems.

Indeck is a world leader in industrial watertube boiler manufacturing and distribution. Indeck’s steam boiler systems include “A” “O” “D” and Modular “D” designs. Currently, our watertube boilers provide reliable steam to industrial facilities and large commercial campuses in over 50 countries worldwide.

How Does a Watertube Boiler Work?

Water circulation is a crucial aspect of how watertube boilers work. In these industrial boilers, water flows through the tubes while hot gases surround them. This circulation allows for efficient heat transfer and prevents the tubes from overheating.

Heat transfer plays a vital role in the operation of watertube boilers. The hot gases produced by fuel combustion pass over the external surfaces of the tubes, transferring heat to the circulating water inside. This process ensures that steam or hot water can be generated at high temperatures and pressures for various industrial applications.

The process of steam or hot water generation in watertube boilers begins with heating the circulating water within the tubes using fuel combustion or other heat sources. As this heated water reaches a boiling point, it turns into steam that can be utilized for power generation or mechanical processes in industries such as manufacturing and energy production.
