Water-tube boilers may vary in design; however, their basic principles of operation are the same. This type of boiler consists of two drums, a series of water tubes, a feedwater inlet line, and a combustion gas outlet stack. These tubes are connected to a steam drum and a mud drum. The water is heated and steam is produced in the upper drum.
