Wood Gasification

[evolvingape]

Here is a slow motion video showing you what happens in a thermobaric explosion:

https://www.youtube.com/watch?v=7dW1qkBg8sM

If you are injecting the fuel vapor (< 10 micron droplets) and air mix into the front chamber of the PPR remember that the HHO shockwave and flame front will be shaped by the LFV in the rear chamber. This will ignite the thermobaric fuel / air mixture and shape that fluid flow via the PPR outlet for injection into the engine. The chamber peak pressure pulse rise time will be extremely fast to generate maximum power, so go easy to start with on how much fuel you inject into the chamber.

Slider's Valve

If you have followed what I am doing then you will know I am attempting to make an automatic pressure governed steam dump valve to run a turbine:

Everyman Automatic PWM Steam Governer Assembly

The simplest version is what I am building and combines a snapvalve with a piston valve QEV:

Snapvalve explained

The build is coming along nicely, and I have promised Slider a complete assembly when I have finished the prototyping, hence Slider's Valve is what I am calling it.

A heat source heats a steam chamber creating a static head of steam pressure. This pressure feeds through a small annular gap past the piston and fills the pilot. When firing pressure is reached the snapvalve opens and vents the pilot volume to atmosphere, creating a pressure drop behind the piston QEV and opening the co-axial barrel sealed chamber. Both valves are spring reset, and both fill from chamber side hence the need for the springs.

I have chosen the barrel sealing co-axial design because the layout gives me snapvalve at the top of the system, piston QEV below it, and the steam pulse is fired down. This will then be integrated with a Pulsometer tube so that the steam gas pulse can be converted efficiently to liquid flow, exploiting the potential difference between high pressure low density steam (gas), and low pressure high density water (liquid).

The Pulsometer water jet will then power a Turgo turbine or variant and convert the rotary moment of the turbine to electricity via the PMA. The first prototype will run using an air compressor for testing, an electrode boiler for accurate and easy "energy in" calculations, and the final version will run from an open fire with eventual upgrade to a gasifier planned.

All of this can be, and will be, built with BSP stainless steel fittings 150lb rated and is part of the Everyman principle. The final device will allow you to light a fire and have hot water for heating, purified water for drinking, and electricity for your use.

12V DC Boiler and Burner

The AC electrode boiler option, provided by a 14mm spark plug and a 1/2” BSP Male to 14mm Female adaptor, allows easy experimentation with AC wall socket power supplied at the frequency your power station generator's output, 50 or 60 Hz normally. Alternatively you could power it from a PMA if you have means to drive it, the frequency being set by the RPM.

A gasifier based system providing the heat source has the option of using this 1/2” BSP heater plug to burn a flame composed of the combustible gases produced by the pyrolysis process. This would heat a boiler in the same way as conventional central heating natural gas systems, as installed in many homes. A stainless steel coil of sufficient length sleeved around the pyrolysis chamber would superheat the steam, ensuring maximum gas expansion before entering the dump valve chamber.

“More and more commercial vehicles are being equipped with “flame” start systems to ease cold starting. Once the heating temperature has been reached, fuel enters the evaporator of the flame heater glow plug via a solenoid valve. A flame is produced that heats the intake air and facilitates reliable, convenient and environmentally friendly cold starting, even at low temperatures.”

Snapvalve Governer Assembly Test

I have just completed the build and test of the Snapvalve Governer Assembly. As you can see the device is functioning perfectly:

Snapvalve Governer Assembly 1st Test - YouTube

Triggering pressure currently unknown until the gauge I need arrives. Next stage is to finish the Piston Valve and then test the two together. If the Snapvalve is sufficient to pilot the Piston Valve then we have a functional injector for our homemade, off the shelf, engine...

Miniature Steam Power Plant

The system the videos are based around is my own personal retirement project, aiming to prove and demonstrate that a heat engine with 10kW net electrical output can be built from off the shelf components and take care of your three primary survival needs; heat, distilled water and electricity. I decided that I would release the information now as the build progresses, rather than wait and release a finished system, so that those working in secret can benefit from the information now. It is important to note that electricity will be the primary output, with low grade heat and distilled water as byproducts of the system operating processes.

The basic principle is a miniature power generation plant, similar to nuclear steam powered plants, but with an alternative small scale heat source running from a fuel supply you control. Here is another look at some of the options available:

Nuclear Reactors | Nuclear Power Plant | Nuclear Reactor Technology


As you can see a nuclear steam power plant uses axial flow turbines which are the most efficient, with overall plant efficiency probably running at around 30 - 35%. The problem we have is that standard radial turbines cannot compete with the efficiency of an axial turbine running on superheated steam, probably only around 10% efficient. A potential solution is as follows...

A heat source provided by a fire will generate a static steam head of pressure in the boiler, which will then release saturated steam in pulses via the dump valve which is automatically pressure differential governed. The steam will power the Pulsometer water pump driving the fluid piston. The water can then either be pumped up to a height substantially above the pump (creating a head) and use a gravity differential for controlled release into the turbine nozzles, or used directly to drive the turbine. The first option separates the water flow control into the turbine injector from the operation of the pump by storing the energy in the gravitational field. The second option means that pressure and flow rates to the turbine will be determined directly by the pump cycling operation and parameters.

A Turgo turbine is around 90% efficient, and the PMA should also be around 90% efficient. The key to all this will be the efficiency of conversion of the heat source, to steam pressure, to water pressure via the Pulsometer. This is where I am looking to make substantial gains over direct steam injection into a radial turbine.

Later on I will be upgrading the open fire heat source to a gasifier which will do two things, it will greatly increase the efficiency of fuel consumption and also provide the ability to superheat the steam making the dump valve produce more output power into the Pulsometer. Basically the fuel will go further, and the engine will produce more power.

I am still working on the piston design for the dump valve as I need a piston that will operate for millions of cycles reliably, later on I will concentrate on reducing the weight of the piston as much as possible to maximise power, but for now a functional system is the priority. Efficiency improvements will come later when we have a baseline system for comparison, and each component is upgraded individually. Only change one variable at a time and you will see the efficiency change as a direct result. Accurate input and output measurement protocol is essential, hence the AC spark plug electrode boiler and DC coil heater plug input options.

Tesla Turbine?

Hi Rob,

Have you given any consideration to a Tesla turbine? They can be built fairly easily even in a simple home shop if you have a metal lathe and can do some simple machining. They can be used with steam, water or hydraulic fluid. They can even be used with wet steam that will destroy other types of turbines. They can also be modified to burn a liquid or a gas fuel.

When I get finished with my house rebuilding project I want to make one that would run on heated freon and turn a generator. I want to heat the freon with a large satellite dish painted silver and designed to track the sun and focused on a heat exchanger.

Just a couple of thoughts to toss your way.

Respectfully,
Carroll

[evolvingape]

Hi Carroll,

The short answer is yes, I have.

When I first started turbine design, not sure when but it was a long time ago, the Tesla turbine was the platform I chose due to its physical properties compatibility with an electrolysis cell:

LONG TIME READER GIFTS US With HYDRO-ELECTROLYTIC TURBINE ON DEMAND SYSTEM (plans)

The Hydro Electro Lytic Turbine HHO generator was the result, released fully open source August 17th 2010.

Personal situation dictated the timing of that release and the build was never completed, by me anyway. The HELT was a stepping stone to this:

RotoMax Rotary Engine... Tesla - Wankel - Mason HHO Hybrid

and this:

HELIS - Hydro Electro Lytic Injector System

HHO Pulse Combustion Turbine by RM

Superheated Electrolysis and Adiabatic Compression

An entirely new hybrid engine turbine concept with both solid state and PWM phase change injectors and a fuel system designed around superheated electrolysis.

All of those projects were beyond my resources to develop and so I gave them to the world to develop independently, fully open source, with the keys hidden in my work only released recently and buried somewhere in this thread.

The current project involving steam dump valves and the Pulsometer water pump only uses off the shelf parts and known technologies and is my personal retirement project that I have decided to share as a build log. When this final project is complete it will be my last.

Enjoy the read Carroll, any questions happy to answer them while I am still around.

Steam Piston Dump Valves

Some more information to help you along in your build...

Heldite Jointing Compound - Heldite Jointing Compound - Sealants (Thread) - Oilybits.com - The U.K's Premier Bio Fuel Equipment Superstore

I will be prototyping with Heldite for joint sealant as it has excellent properties and has been used as a jointing compound for steam applications for a very long time.

Specifications for Cured EPDM Rubber

EPDM Gaskets - EPDM Rubber Gaskets | RH Nuttall

epdm sheet | eBay

Custom stamped EPDM washers from thick sheet using sharpened tube and a mallet, chosen for it's excellent properties including steam resistance, commonly used in O-rings and many types of gasket.

The Snapvalve design you have seen in the video not only works, it is designed to function for millions of cycles before failure, hence the self lubricating oilite bush. This is what we need when designing an engine, obviously I have not tested it yet for millions of cycles but I am confident it will perform well, hence the video showing you how to make it.

The piston valve will follow a very similar design with a single housing tube inside the chamber tee, epdm face seal, and radial porting around the entire circumference making sure to maintain structural integrity by not drilling the holes too close together. High temperature neodymium magnets integrated into both piston and housing in repulsion mode providing spring reset when filled from chamber side, ensuring no crushed wire springs. Do not forget the equalisation hole behind the dump piston, which is closed when the pressure drop from the Snapvalve governer pulls the piston back, opening the radial porting to the exhaust. Alternatively file very shallow flats along the length of the piston and use the radial porting holes as the equalisation holes, the same as you would with a dowel pin to prevent air spring.

When I have the time I will show you this as well, but I want you to have a go at it first, you will learn more that way.

Yes woodgas works for powering an entire home or office.



Woodgas and the burning of water should easily power and heat a home.

Running LED's would not get a field plowed for planting a crop in the event of a shortage of fuel. An electric tractor is out.

storing

Hi Guys, Just recently been reading about this stuff, but haven't seen anybody storing the fuel ,they all burn it right away.
Does anybody know if we can maybe fill empty barbecue tanks ? Or some other way.
