Fuel is burned inside the furnace creating hot gas which heats water in the steam generating tubes in smaller boilers additional generating tubes are separate in the furnace while larger utility boilers rely on the water filled tubes.
The heat of the gases is transferred through the walls of the tubes by thermal conduction heating the water and ultimately creating steam. Actually this boiler is just opposite of fire tube boiler where hot gasses are passed through tubes which are surrounded by water. We briefly discuss about water tube boiler parts and functions.

Water tube boilers were developed for a variety of reasons including the need for higher steam pressures higher steam generation rate superheated steam. The energy from the heat source may be extracted as either radiant or convection and conduction. These types of boilers have quicker response to load changes.
The water tube boiler diagram is shown below and these two drums are associated via two tubes such as downcomer and riser.
