Water Tube Boilers | Spirax Sarco

The water within the water drum, and the connecting pipes to the other two upper drums, are heated, and the steam bubbles produced rise into the upper drums where the steam is then taken off. The bent tube or Stirling boiler allows for a large surface heat transfer area, as well as promoting natural water circulation.

Steam Boiler: Circulation Water in Steam Boiler

Circulation of water in the pipes/tubes in steam boiler is a very important thing to be designed. Boiler must be designed in such a way that avoided the formation of steam and out of the water wall tubes from steam drum. In other words, should not be going back-flow.
