The main components of a water tube boiler are the furnace, the tubes, the drums, the gas/oil burner, and the economizer. Cool water comes in through the inlet and then flows down the downcomer to then be heat in the pipes. As it heats the warmer water then begins to rise up the risers until it boils and becomes steam.

What is Water-tube Boiler? | Technology-Articles.com
Modern water-tube boiler, equipped with water pipes designed as the boiler walls (wall-tube). Water from the steam drum goes down through a pipe called downcomer to the header pipe (lower ring header) connected to all the lower ends of the wall-tube. The other end of the wall-tube at the top of the combustion chamber is directly connected to the steam drum. In the wall-tube, there is a phase change from water to steam.

Dynamic Shrink/Swell and Boiler Level Control – Control Guru
The tubes producing large quantities of steam are termed risers and those principally carrying water down to the mud drum from the steam drum are termed downcomers. Excluding the tubes subject to radiant heat input from the firebox flame, a given tube will serve as a riser at some firing rates and a downcomer at other firing rates. The mechanics of the natural convection circulation of boiler water within the steam generator is the origin of the dynamic shrink/swell phenomenon.
