The Steam Plant
Above: the lower portion of the boiler front, showing the firehole door with the chained fuel filler cap in the foreground. The 2" door was turned from Naval Brass, reclaimed from the propeller shaft of an old lobster-fishing boat.
My initial was cut in the glass firehole door window with a Dremel Tool. The vertical stainless steel and brass arm assembly is ganged to wick adjustments on three of the Kerosene burners. It has a counterpart to the right (seen here poking up behind the fuel cap) to control the other three burners.
The square brass plug provides access for cleaning the port mud drum on the Yarrow-style boiler. The shiny metal end of the port water tank is visible on the right side of the picture. The red-capped feedwater filter is fashioned after one used in oil-fired home heating systems. Visible behind the filter is the green-painted manual feed pump.
BELOW: The stack base and top steam manifold showing the homemade stack temperature gauge. Four valves are visible: Pressure relief, whistle shut-off, steam blower and the main safty valve.
These shots of the port side give a good idea of the arrangement of the engine behind the boiler and the location of the water tanks. The long black vertical cylinder at the back of the boiler is an exhaust steam separator. The sliver horizontal tank at the bottom of the separator is the feedwater heater. A brass vertical air chamber attached to the feed pump is also visible.
The three-drum boiler is made from copper, but the extensive use of stainless steel can be seen here in the double- walled boiler casing, the stack and the two side water tanks. Brass, bronze and some aluminum are also used, as well as cast iron, gunmetal and steel on the engine.
The whistle has been changed to this single-note, organ-style ship's type - a little less glamorous perhaps, but more functional over a wider range of steam pressures.
This image appears elsewhere on the site, but I have included it again as it gives a good idea of how the plant looks from the starboard rear quarter.
