A steam condenser condenses steam and the heat released by the steam is absorbed by water. A surface condenser passes the stem over the outer surface of tubes through which cooling water is pumped. This is basically the same as a radiator in a car. My model of a condenser is of a Down-Flow type where the cooling water enters the condenser at the lower section and after traveling through the upper section comes out the outlet. The exhaust steam enters from the top, flows down over the tubes and is removed via an extraction pump.
My model vaguely follows this pattern but mostly was designed to look interesting. For my modeling, “interesting” beats out reality often as not. The condenser and pumps and plumbing may not be visible at all from the skylight or perhaps only partial. Either is fine .. I am just having fun designing this bit of the engine room.
I will be painting them a different color than the green I painted the engine with for contrast. This is of course assuming they can be seen at all. If so the different color/hue will say they are from another company or division.
- The Water pump takes seawater in so it needs to plumb through the engine room floor.
- The Extraction pump needs to feed the boiler so it needs to plumb into the forward wall of the engine room.
- The Exhaust seam connects to the exhaust on the engine.
- The Water outlet plumbs to the outer wall of the engine room.
