I should include these pictures aswell
the first one is the connection to the feed pump to the water reservoir(water tank), and the second is a picture of the water tank I think its capacity is about 25 gallons.

Could someone change the courtesy edit time to 10 minutes this is what I do on my forum. I can understand the limit on editing because someone can edit there post way after it was posted (how you used to have) like unlimited how it was set. I was in a situation where the page flipped and wanted to include the pictures on the previous page

Yes, or you can do it with picture...your choice. I often stage this type of assembly mock-up, example attached. Feed water heater for my scooter.

Looks good Rick... I still think you should be a moderator

Jeremy my friend...I'll look into it. Part of my dilemma is that I'm in an apartment, in-between houses. This forum fills a void for not performing experiments, play time in my shop.
Enough of me, how is the mock-up coming? Take your time, no rush.
Last picture is of some sort of fuel injector for steam, on steroids In my post, I believe you stated that this can handle super critical (SC) steam. I'm thinking a SS construction? Tell me about this design?

Hi Rick,
Yes the injector valve can handle SC steam. The construction is 316L and a special graphite impregnated spring loaded seal. The tolerances are super tight and probably work without the seal.
The injector is electronically actuated. So the user can use variable cutoff advance and such. The solenoid is 12vdc with a water cooled wire. The real innovation is that its variable lift thru a system of primary and secondary stops. I tested it dynamically and it throttles very efficiently.

Hi Jeremy,
Take your time. However, you get the coveted "Tip-Of-The-Hat"
You have this device patented...you did it!
Am I correct in the application, to release SC steam right into the Cylinder? Please explain? Sorry for asking so many question, hope you don't mind.
Kind regards,
Rick

Hi Rick,
I have done my best to explain the 4 cycle flash steam engine Flash steam
Just spend some time reading on that page, there are some links on that page links to. I hope I have provided enough info to explain to current design

Jeremy,
Let me complete looking through it. I'm relating it to thermodynamics and T-S diagrams. Let me review it a little more. I hope to point out the stumble block so to get you past the stall.
Here is a little bit that I think where you are coming from. You like a solid fuel, renewable, system. The system seams to have co-generation. These are two points I think are sweet If Craig goes to the meet, I would like you to talk with him about his ideas. You two are on the same parallel path.
We should talk Rocket Stoves also, sometime. This is another interesting area after we get through this one.
I'll be back...
Kind regards,
Rick

You like a solid fuel, renewable, system.
Back in the day when I was burning 4 to 6 hours a day, the only way I could, was using corn kernels as the primary fuel it was just cheaper thats the reasoning for it.
On the next combustion chamber its going to have an auxiliary kerosene vaporizing burner as a secondary on the afterburner unit..
I think its really important to work with the burner the more you experiment you can perform over the long run teaches you thermodynamics
This is the state of the system before the super heater, I hand built all of this, including the aluminium welding.

Hi Jeremy,
Let's get to technical stuff...efficiency. You know how to calculate, can I see the numbers? Probably best to do it in numbers of temperature. Let us take a look at just temperature at this point and we'll factor in the work required to achieve HP, SC water. I'm thinking this is where the challenge is, to be conquered.
Also, what are the numbers for Pressure and Temperature going into the injector? I'm sure you know that the road to the best efficiency, break through as a matter of fact, is to go super critical (SC). The numbers you need are ~3,000 PSI and ~700 degree F. The 700 club is easy to obtain. However, the pressure is a challenge to me. This is why I'm very interested in your project...how do you obtain the SC pressure?
Back when I was working with Gas Turbine Engines, the Stealth Cruise Missile Turbine Engine, we tested the girl in high altitude chamber. We had a HP compressor. It was in two (2) stages, one is like the compressor you and Jamison might use and the other was smaller and looked like it was on steroids. There were double the rings, seals and the diameter of the rods. It took like an hour to get to 2,000 psi before we could run. Reason mentioning it is the wonder if this is where one needs go to achieve the SC pressures.
Wonder also, what is the diameter of tubing to the injector?
Hope this is helpful.
Last, when building my oil injector, I had a thought about this arrangement to achieve high pressure, ultra high that is....rhetorical? Stanley oil pump attached.
Cheers my friend,
Rick

Re: 4 cycle Flash Steam Engine February 18, 2019 11:55AM |
Hi Jeremy,
Sorry, I missed that you came clean with stating a 60% efficiency. My guess is this is a thermal efficiency and not a total efficiency? In other words you're using an equation like:
n=1-(T1-T2)/T1, Note that the n is supposed to be this fancy character with a tail (represents efficiency).
This called the Carnot Efficiency.
Respectfully, with kind intentions, I would challenge the 60%
Keep in mind I would like to explore the energy required by the pump. What Horsepower is needed to run the pump(s)? We can get to this later. Another point to discuss is the Stoichiometric efficiency. This is regarding the burner or heat source, how efficient is this process?
Another thing is looking out for sensitive IP, i.e. I'm interested in a HTE burner that will be ultra high efficiency and break through. I need SC steam to do that and hence the synergy with your system. What I'm not going to tell anyone on this forum, the process to make the electrodes. I believe we will come to a similar stumbling point with your system. You can keep that part quiet. You have a patent on the injector, this is a key element towards your IP protection.
Kind regards,
Rick

Re: 4 cycle Flash Steam Engine February 18, 2019 12:36PM |
The thing should be considered as re-using steam without condensing. That is a feature that aims to prove 60%.
Im not in this for easy construct of steam engines. I want to pioneer a more efficient steam engine.

Hi,
Still working on my homework assignment. If you are willing, please provide 2 PV diagrams for your engine? One will represent the Intake/compression and the other the expansion/exhaust. This will cover a 4Pi cycle. I attached some examples. One is actual measured and plotted.
Note that I did laugh at your joke, pretty funny
I'm going stir crazy. I'm between shops and going through with drawls....
Cheers,
Rick

This is a rough idea of the cycle. The only thing that concerns me is at the rise of the map is adiabatic has no heat transfer wheras it should. At the instant of flash steam there is/should be heat transfer albeit as the Heat of rejection dictates.
Although Heat of rejection notes a decease in heat transfer which is a semi adiabatic process, there is still some thermal heat transfer.
