Coal fired Scotch fire tube boiler with three furnaces.
The stoker is banking up the furnace, i.e., he packs embers and coals tight
together so they don't burn but smoulder. Next morning there will be sufficient
live coal to start up the fire again.
The reciprocating compound steam engine. The crosshead and connecting rod for
the high pressure piston and the eccentrics and the reversing motion links for
both pistons.
The Flodman reversing link motion works very much like the
Klug reversing gear.
