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...

Re: Resources/Information for Crank Lubrication?

That crank is beautiful Lionel, and it's really making me reconsider bolting mine together. I'm not really familiar with the 6A, so where does the eccentric for the cylinder away from the camera go? The engine I'm planning this for is going to be a pyramidal 5-cylinder quadruple expansion with a reh...

Resources/Information for Crank Lubrication?

I'm currently working on my own engine design, and it seems like the biggest source of headaches is the crankshaft design and lubrication. I haven't been able to find anything regarding the crank bearings or lubrication. I'm currently planning on doing something along the lines of a built-up, bolted...

Re: Steam Thruster?

Another advantage of the trolling motor is safety. A lot of models are remote control from a keyfob, which means that if you ever fall overboard with the throttle shut you can use the trolling motor to bring the boat back to you. Maybe more of a concern for a fishing vessel, but still it can't hurt.
