Re: Steam Actuated Inlet Valves?

Wow, this took off way more than I expected it to. To respond to a few of the observations: 1. It should be possible to run this at boiler pressure. All that should be necessary is that the surface area of the piston attached to the main valve be larger than that of the valve, and there will be suff...

Re: Oil/Water Separator

To remove oil from water, you must use an oil that does not emulsify with water, once it is emulsified, you cannot remove the oil, unless you boil away the oily water, leaving the oil behind, but that does not generally work on a steamboat. Pure Mineral oil is separable from water, virtually any ty...

Steam Actuated Inlet Valves?

Would it be possible to actuate the opening and closing of valves directly by using steam? Essentially, I'm thinking of a situation where a small amount of steam could be admitted to a small cylinder via a small solenoid. This steam would then force itself against the piston, which is attached to th...

Oil/Water Separator

Those of you running condensing plants, what do you do do remove oil from the condensate before sending it back to the boiler?

Re: Resources/Information for Crank Lubrication?

Triangletom, 2- The amount of steam that would go into the HP cylinder would be a tiny fraction of what would be required to run the 2 x 5LP cylinders - not even enough to register on a pressure gauge I wouldn't wonder! This means that both the HP and 1IP cylinders would be required to run non-expa...

Re: Resources/Information for Crank Lubrication?

Wouldn't even need to be a truck engine. Something small would probably handle the load. Like a Suzuki Samurai or some such thing. The limit would be the minimum bore spacing at the low pressure end. How many crank throws does this dilithium crystal need anyway? Whadaya think, Scottie? I'm planning...

Re: Resources/Information for Crank Lubrication?

I see what you mean now regarding the SA/V ratio. I'm actually planning on tapping the reheated line for a steam jacket around the HP cylinder so that heat actually flows inwards, but like I said the math isn't done yet. When I eventually do get it built, I'll be certain to post it everywhere. And t...

Re: Resources/Information for Crank Lubrication?

You're right that the quad is for efficiency, but it's a strange engine to think about. Essentially it's a small superheated HP engine that exhausts at 120 PSI and a large superheated LP engine that exhausts around 5 PSI. Based on the math I've done so far, there won't be any condensation in the HP ...

Thanks for that Lionel! It explains a lot.

Re: Resources/Information for Crank Lubrication?

How big is this engine to be? Bores and stroke? 1 7/8"+3 7/8"+8 1/8"+ (2) 10" X 7 inch stroke. I'm still doing the math on the heat transfer in and out of the cylinders and resuperheater as well as condensation in the valves and receivers, so those bore numbers are subject to a little further refin...
