Field-tube boiler - Wikipedia
Field-tubes are always submerged, i.e. the upper end of the tube is mounted into the boiler below the water level, otherwise flow into the cold side of the tube cannot be replenished. The principal advantage claimed for Field-tube boilers is that there are none of the expansion problems experienced in boilers with simple tubes.
