Note the boiler is not fitted with a superheater. In the standard steam locomotive fire-tube boiler, the firebox is surrounded by water space on five sides. The bottom of the firebox is open to atmospheric pressure, but covered by fire grates (solid fuel) or a firing pan (liquid fuel).

The fire room of the battleship USS Massachusetts. On a ship, the fire room, or FR or boiler room or stokehold, referred to the space, or spaces, of a vessel where water was brought to a boil. The steam was then transmitted to a separate engine room, often (but not always) located immediately aft, where it was utilized to power the vessel.
return-tube boiler: fire-tube boiler with multiple small fire-tubes that reverse the direction of gas flow within the boiler. Individual tubes are not folded: there is usually a furnace, a combustion chamber that reverses the flow, then the tubes return from that. The Scotch is a well-known example of this type. Robertson boiler
Electric steam boilers are more efficient than fire-heated boilers because they require less energy to be put into them for operation at capacity. This is because there is little energy lost when the transfer of heat from the heating element to the water occurs, unlike traditional fire heated boilers, where there is a substantial amount of ...
Where such a boiler may be heated either by the exhaust gases of the main propulsion plant, or else separately fired when in port (usually by oil rather than coal) it is referred to as a composite boiler. [4] The boiler is a cylindrical vertical water drum with a hemispherical domed top. This domed shape is strong enough not to require staying.

On steam locomotives, firemen were not usually responsible for initially preparing locomotives and lighting their fires. As a locomotive boiler takes several hours to heat up, and a too-rapid fire-raising can cause excess wear on a boiler, this task was usually performed by fire lighters working some hours before the fireman's main shift started.
