Re: digital steam engine indicator

So, The separate calculation of the medium pressure is done. The calculation of the power is done. Everything is prepared so far for the addition of the display. Now, my todo list has changed a little: The metric/imperial options will definitely be implemented. It's too easy not to do. It is just us...

Re: digital steam engine indicator

I fired a lot tonight:) To water the mouths, I give a short update of what I've accomplished so far: Translation of the encoder signal into the crank angle. Calculation of the piston position (The crank radius and con rod length still are written into the code as constants). Shifting the piston posi...

Re: digital steam engine indicator

Well, I'll not be making money off of this. This is a project, which is interesting for me and if it can be helpful for others, it is reward enough. I actually have cheap pressure transducers in mind, which are available for different pressure arrays and have a reaction time of 1-2 ms. I suspect the...

Re: digital steam engine indicator

So, Unfortunately, I've not found time for my interests, but I've now proceeded with the digital steam engine indicator. I've now fully finished everything going on on the x-axis of the indicator diagram. Fortunately, this has been the more complicated part. To accomplish this, I've sherlocked the i...

Well, thanks, that you can identify the engine as unsuitable. I thought it was a big one. You prevented a disappointed face.

Stuart Twin for Sale for 600€, negotiable - I offer to organize negotiations and shippment if someone prefers that.

Hey, If someone needs a Stuart Twin steam engine - there is one on offer on a german version of craigslist. The text says as follows: The owner just bought it himself some weeks ago, but didn't think that the engine would need a bigger boiler than he could possibly install into his steam boat. The p...

Re: Oil inside the condenser

Interesting. I intend to try out different oil separation methods with my engine on a kind of test series.

So what you are saying implies the condenser regularily gets washed out to get the pipes clean again? I am asking because I've never read anything adressing this issue anywhere.

Re: How to design a monotube steam separator?

As always, many thanks. This is exactly what I was hoping for. By the way: Do you think your steam is very dry already? (In your "machine gun" monotube) I am asking because I was thinking of placing a cyclone separator inside the top of the flask. It'll definitely not hurt, but if the tangential inl...

Re: Any german steam boat captains reachable?

I already found it, but many thanks of course. They seem to have the same restrictions, that finding an address is rare, but I've found a phone number to ring through.

How to design a monotube steam separator?

Hey, Is there any rule to design a steam separator? My monotube test boiler will have 9 sqft of HS equally split between radiation and convection HS and should spit out roughly around 50-60 pph. To be clear, I am talking about the drum-like flask. is there a rot for how much water it has to contain ...
