Steam question |
|

|
is there a way to get the water out of the steam before it gets |
|
to the driven mechanism, so there 's not such a mess? |

Hi, some diagrams show a super heater coil. I have noticed when |
|
the engine is cold at start up the steam condenses and after the |
|
engine warms up the problem goes away. |

The major mistake I made was using black iron unions, they rust |
|
really fast. I plan to use bronze on all future efforts. |

Steam is water in a changed state. In most steam engines of old |
|
the steam loses a lot of heat when it does work and changes back |
|
to water. While the steam is fairly dry in the inlet as soon as |
|
it leaks out of valves, cylinders etc it forms water droplets. |
|
Steam is very difficult to seal. An analogy would be water is |
|
like big rocks in your hands, steam is like fine sand. |
|
Also, keep in mind different steam engines are setup to work |
|
with varying degrees of saturated steam or superheated "dry" |
|
steam. A "simple" engine (not compounding) may run poorly on |
|
superheated steam. A compound engine wont run on saturated |
|
steam well if at all because in the last stage the steam may |
|
collapse and cause a vacuum causing the piston to run the wrong |
|
direction. |
|
If a steam engine is designed well and the steam is at the right |
|
temperature it's possible to see very little condensate coming |
|
from the engine. |
|
In good steam engine design the steam 'hot" side is all very |
|
well insulated so there is much less condensate. |
