So, it is hard to understand why they would introduce steam/water into a tank car full of Bunker C rather than circulate through a series of pipes and then let it vent to the outside. In addition, my understanding from what he told me is that water flowed to the surface of a steam locomotive tender not to a low point…
If you are commenting on my road oil tankcar, they are not introducing steam into the oil, but rather into the heating coils, which are a closed system. What Chuck is saying is you don't need to vent steam out the other end of the coil; as the steam gives up its heat, it condenses to water, which trickles down to the steam trap, where it is expelled from the system, same as a passenger car heating system, or, for that matter, my building heating system. If I recall the function of the steam traps correctly, they have a bi-metallic diaphragm that when covered by water, cools enough to pop open. With the water gone and steam flowing by, the diaphragm heats up enough to pop closed again.
