Steam bubbles form in the hottest tubes and rise to the steam drum where
the steam is separated out of the water and steam mixture. Circulation is
maintained by water returning to the mud drum through the cooler tubes.
The hotter tubes (the risers) are the ones in the radiant area of the furnace
and the hottest areas of the generating bank of tubes.

the air heater to the
stack.
