Boiler Design: Composition Benefits & How to Start ...

This type of boiler consists of two drums a set of water tubes a feedwater channel line and a combustion gas vent stack. These pipes are attached to a steam drum and a mud drum. The water is boiled and steam is generated in the upper drum. Water-tube design boilers are quite fit for applications needing large amounts of steam such as industrial process purposes and are used less often for
