Re: Steam Actuated Inlet Valves?

Skinner of course used two cams running running at the same speed, and adjusted the phase angle between the cams to achieve a wide range of cut-offs, from 5 or 10% to over 50% - necessary since those engines were often used in direct reversing marine service, and reliable reversing is essential. Th...

Re: Heavy Duty Trailer cover

Alright, keeping in mind that virtually all of my experience is in moving furniture; If you want to do this on a tighter budget, look at using a few tarps instead of just one. I'd recommend wrapping the VFT by itself,with a liberal amount of ratchet ties to keep flapping to a minimum. The biggest ki...

What are you going to do with the exhaust valve?

Lionel
Because timing isn't quite as important as the inlet valve, I figured either a uniflow design or cam driven poppet would be suitable.

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...

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...
