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 smoking smiley

The Edit time has not changed on this site since it was added to Phorum years ago. (unlimited)
I sent you an email.

Hi Rick,

Its rained the past couple days. I was thinking about doing a mock-up with all the components on film, if your interested let me know.

Im talking electronics the whole nine yards etc. There is a control panel that know-body has seen and Im still working on and the dam super-heater. But the mock up will be really close to the final design.

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.

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 smiling smiley 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?
Re: 4 cycle Flash Steam Engine

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" thumbs up thumbs up thumbs up 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 smiling smiley

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 smiling smiley 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

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,
Your test rig and its components is awesome!

I have some advice when you invent. People will comment that it won't work, you're barking up the wrong tree and or they make fun of what you're doing...this is good. I take that kind of response and think I'm on the right track. Most likely, the people making comments are thinking that I should have thought of that. Or could have built that. Everyone has opinions and ideas, its like everyone has ash wholes. Its the ones who turn an idea into reality are omnipotent, the real creators in society...hope this helps.

OK, Your system as I see it is a combined cycle. You have combined the Diesel Cycle with the Rankin Cycle. The four strokes of your engine are defined in Diesel Cycle and the expansive work of the steam in the Rankin. You are using a hit and miss engine, excellent choice BTW, to demonstrate this Combined Cycle. You know I like combining cycles and often call it a Hybrid, i.e. my How I would build my Boiler thread.

Also, you are taking advantage of Carnot Efficiency with the way the steam is re-used, reheated to keep the efficiency up. Then as I understand the working diagram, you will use the exhaust heat for another cogeneration purpose like heating a house.

In summary, you have a sound concept that is feasible and works as you have demonstrated.

Kind regards,
Rick

Dont worry about the knee jerk reaction of my previous posts. Im not used to someone saying hey I find something interesting about that.

Im going to come clean,,, about projected efficiency I want to achieve 60% eff. some steam is being reused without condensing.

Its kind of funny I had this guy working for me. And he remarked whats the deal with music in the shop, is it banned or what. I said yes we dont listen it to work.

I find it appropriate went were not using any heavy equipment and are inventing.

I know im claiming a hi efficiency on the expander of 60%. I dont know what it will take to prove that.

Just as an aside Harry is making us that are in genuine effort, look bad. 30% total efficiency BIG DEAL....

I was at Harrys shop a couple times and all they wanted me to do was to sign a non compete. I wouldn't sign it and they showed me the door straightaway...

I honestly believe Harry is wrecking us and our development. Although its all in the name of money.

A guy like me comes along and have to be looked down because of Harry.

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% eye popping smiley

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

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.

Ahhh my old friend stoichiometry, The combustion that the by products are just water vapor, maybe some Co2.

When I burn corn the efficiency is quite good. Just a little FYI burning corn kernels is exempt from EPA regulation. The secondary kerosene burner, has a pump that can be adjusted to achieve optimum burn/feed rate.


A better question is how many GPM the feed pump supply's to the injector. The idea is that measuring what amount of flow is supplied. Water has a 1600 to 1 expansion ratio. In other words less the flow requirement since its flashing to steam, the output gpm is far less than traditional requirements. applications like this don't need a lot of flow so the feed pump can be driven with an under drive, this makes the load on the feed pump much less.


Take for example the recent work on feed water pump ratio, I have made that can see 3000psi cranked over easily by hand. This is possible because there is not a high requirement of flow. Now my next step is to allow the injector to not be connected to the piston chamber, and free in the open air, and analyze the spray pattern, once I see what im looking for we will proceed.

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 smiling smiley

I'm going stir crazy. I'm between shops and going through with drawls....

Cheers,
Rick


Re: 4 cycle Flash Steam Engine
February 20, 2019 09:21AM
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.
