Power your home and workshop with steam

First Thank you for reading my instructable. This is a work in progress, I will be adding more and more to this instructable on how to build a steam driven turbine and power plant for your home. As always if you find any typo's or any mistakes please let me know there is a lot of information I am going to throw your way. So lets get started.

I am going to show you how I build this 45 Kilowatt Genset, or steam turbine to power my home and business.  This unit was a major effort to get off the ground. I will attempt to show you how to build this beauty.  Perhaps you can build one on a smaller scale. This unit is not for the amature. This build is very difficult and dangerous. There are a few things you need to be aware of when working with high power. 

 1. Respect the power. It will kill you in a heartbeat. 
 2. DO NOT ATTEMPT THE PROJECT IF YOU DON'T KNOW HOW TO WORK WITH HIGH VOLTAGE AND HIGH PRESSURE STEAM.
 3. BE REALISTIC. If you don't have the equipment to build this device then send the parts out to be made. 
 4. What you don't know, ask. I will be happy to help anyone in any I can.

Always wear safety glasses and proper protection when working with electronics and steam. 

  Ok this is the turbine and generator attached together on the test stand. This is a turbine of my own design the generator portion or Technically the Alternator to be more precise is as mentioned above 45 kw  3 phase AC power output. The turbine in order to produce that level of power it required to run at an astounding 100000 rpm, thats right 100000. Now that will ruin your day if you have a major malfunction this runs at ballistic levels so if you have a destructive or catastrophic event the shrapnel will kill you. It would literally explode. This will turn you into a red mist. That said I have maintained my rpm to more respectable and safe level of around 50000 rpm my power output drops, as should be expected. Though I feel safer at that rpm. My power levels at 50k are about half of my top end of 100k so around 22 kw output 3 phase. 

  This is more that enough for my purposes. So here is the layout and break down of the genset. From right to left. The large cylinders are far right the alternator  left of that larger alum housing is the turbine chamber, the input to the turbine is via the silver high pressure line you see entering the turbine. This LIne is rated for 10000 psi at over 800 degrees. My steam unit runs at a max of 500 degrees F so i have plenty of worry room from a potential runaway. The steam unit will be discussed later right now turbine. so after we see the input line to the left of that you will see the oil pump system I have to use turbine oil rated for aircraft turbines. 150.00 per 5 gallon drum. This is great for the protection of the bearings. I am running hydrostatic bearing at the front of the turbine and a ceramic at the rear. both rated for very high rpm. The pump is a standard 110v ac motor driving a screw pump to maintain pressure at 55 psi for the hydrostatic bearing. the oil is also use to cool the alternator during runs. the oil is returned to the bath via a radiator or heat exchanger. 

just below the alternator portion on the right you can see the pressure sensor and oil filter setup, I use a standard automotive sending unit to give me my oil pressure  more on that later. In the following steps I will show you more detail for the components of the system.

the top drawer housed the control panel. This is the basic layout of the genset.

At first I thought you were working with 'Dead Steam' because of the 'Yellow' control valve being rated at 10,000 lbs.
I had a look at the video you posted and found it to be using 'Live' steam.
What ah relief. Not that Live steam is Any Less dangerous.

What did you want to do with this Power Source? Operate ah Ship?
You should be "Featured" for this one.

wow this is complex

You probably already know this, but just a word of warning for any readers who decide to build something similar:

Be *very* careful designing your boiler. Be especially careful about your selection of a safety valve, bigger is not always better. See, when you increase the pressure on the water, you increase its boiling point. It is perfectly possible to have water in your boiler that is hotter than 100C. Now you exceed your pop valve's threshold and it starts venting. If you drop the pressure too rapidly you can easily have it decrease to the point where the water is well above boiling.

Now, when that happens, how much of the water do you think is going to flash to steam? That's right boys and girls. ALL of it. The amount of pressure generated by this happening can easily make a case of dynamite look like a 4th of July firecracker.

The moral is: Don't just get a tank thick enough to hold ten times the pressure you plan to use and assume you're good. Make sure you know something about steam and how it behaves. Because it doesn't have to be your relief valve to set of this kind of reaction. It can just as easily be a bad bolt, or even the load you're putting on the boiler if it's not properly balanced. There are plenty of good books on the subject. Read them before you fire anything up.

Would you consider attaching the designs so that *ahem* "others" might follow in your footsteps?

Also, I see the video of you testing the boiler, but have you spun up the turbine yet? (I'd be curious to see it in action!)

At the end of the instructsble is a link to my videos it is last vid bottom right. The turbine runs great. Will at to is soon very busy with new robot project at this time sorry.

Why is the boiler so overbuilt if a pop-off at only 150psi is used?

Who is "John Galt" :?
WOW wow wow wow WAIT!

I've been thinking of making a low scale thermo solar generator for a while, I think that (if I got everything right) you just solved the hardest part to do so. you just have to add a solar collector to power the boiler. this is great!

Hi!
Am I correct in saying that you use electricity to boil water and use that steam to drive a turbine?
means you are using electricity to produce electricity?
Where can it be used then as it uses power to generate power?
sparten11 (author)  pranjal121 year ago
The steam cell is multi fuel. The setup as you see it as stated in the instrucsble is for testing the turbine. when done the power pack is removed and the boiler is installed into a firebox. as stated it us used for testing.

what are you some kind of genius? post after post is high tech. awesome. Wish I could do half what you have done.
sparten11 (author) 1 year ago
the rotor is really new and unique. the power unit is purchased. and customized. very much so. the whole system was built to test new rotor designs and power generation inefficiency, and look for improvements.
sparten11 (author) 1 year ago
sorry the steam unit is for testing the turbine. it will also run multi fuel. just place the boiler in fire and steam. for emergency. no perpetual motion. the turbine i built myself new rotor design. the steam unit i build as well new design. i will post more pics of rotor and other parts.

Am I missing something? Your generator is steam powered, your steam boiler is electric powered? Trying to make a perpetual motion machine?

Separately, did you machine your own turbine or buy components? If purchased, what and where? Same questions for the alternator.
