DTU Updraft Gasifier and Stirling EngineDTU Updraft Gasifier and Stirling Engine

Today, operation started on Stirling DK's latest installation situated on the campus areas of the Technical University of Denmark (DTU). Approximately 1% of DTU's total power consumption and 2% of its heat consumption will be supplied by the installation.

The plant includes a Stirling engine with an output of 35 kWe of electrical power. The surplus heat from the plant, in the form of hot water, is fed into the district heating system of the DTU campus.

The plant is fuelled by wood chips originationg partly from cuttings from DTU park areas. In this way, the plant is a stand-alone facility that enables DTU to become partly self-sufficient with CO2-neutral power and heat from locally availabel fuel sources.

More information about the project can be found here.

A new Powerhearth for the marketplace!

A new Powerhearth for the marketplace!
Bill Klein, 3i, October 6, 2009

3i (International Innovations Incorporated), the manufacturers of the world famous Powerhearth, an environmentally friendly biomass conversion system, proudly announce the availability of the Mini Powerhearth in sizes from 5 to 25 KWe. Please find several photographs on the Gasification List web site or contact us directly.

The photographs are of a newly commissioned 5 KWe Powerhearth, shortly after its final testing before delivery to the customer.

This particular unit is a trailer mounted model and will be used in the woods by the customer/logger as a power source for his portable sawmill. By choice, it will be manually operated and batch loaded.

Our regular production model would be outfitted with a continuous feed, airtight auger system from an adjacent metering bin.

We first began work on the great grandparents of this little guy in 2006 and, after thousands of hours of testing, decided we could finally commercialize the model last June. Though a "hunk of metal", we think it's beautiful and it works so bloody well!

A few stats:

Fixed bed, downdraft, linear hearth biomass conversion system

Two inch throat

Makes in excess of 10 cfm gas flow, measured after the gas cooler/cleaner/polisher

Length - without shrouds: 1.5 feet

Width - without shrouds: 1.16 feet

Height: Just under four feet

Weight: approximately 500 lbs.

Operating temperature: 1,250 - 1,300 C

Turndown test - 12 hours: less than 2 cfm

Prior to shipment, each unit undergoes 2 24 hour non stop tests and a 100 hour non stop certification test. The same tests are repeated during commissioning, but with engine(s) and electronics, computers, etc. fully integrated**

** As an option, the unit is capable of full automation, including ash removal and is sized appropriately to maintain net output and parasitic load.

Feedstock: wood chips* 15 to 25% mc and produces a clean and clear flare.

Ash content: approximately 0.25%, but may go as high as 0.5% - clean, fine ash w/o visible char

* As part of the test protocol, each Powerhearth is tested with briquettes of various origin as a check for versatility. Briquettes include green waste, bagasse, non putrescent MSW, black coal, brown coal, rubber, sewage sludge, livestock waste, certain plastics and RDF.

We believe this to be the smallest commercial gasifier capable of producing clean, engine ready, gas 24/7. Each unit is accompanied by the same Powerhearth performance guarantee and full service warranty.

Respectfully,

Bill Klein

Powerhearth: the power of energy independence. It's your choice!

Gasification of Wood Chip Waste for Domestic Heat and Power - January 2009.

Gasification of Wood Chip Waste for Domestic Heat and Power - January 2009.
Ken Boak, January 30, 2009

Lister
Lister

This is my 1953 6hp Lister diesel Startomatic
generator set installed in the renewable energy
workshop. It supplies heated water and power
to my house. Currently it runs on waste veg oil.

The aim is to run this engine using wood gas
produced from woodchip waste from tree
surgery, plus about 20% veg oil in dual fuel
mode.

Engines have been powered on wood gas for
just over 100 years, with main developments in
Europe and Scandinavia occurring during
wartime fuel shortages in the 1940s.

These pages look at my wood gas project.

Video of Honda Accord with GEK driving

Video of Honda Accord with GEK driving
Jim Mason, All Power Labs, Berkeley, CA, January 8, 2009

Here's the video of the first drive of the honda with the modified GEK in the trunk. The drive was around oakland and Berkeley California.
http://www.youtube.com/watch?v=8JyazgRBtq8&eurl=http://www.instructables.com/id/Convert_your_Honda_Accord_to_run_on_trash/&feature=player_embedded

Again the point of this side hopper adaptation of the GEK is to get the gasifier into a more horizontal form factor, which better fits in cars, as well as eliminate the drying loads from the combustion zone.

The architecture here uses the waste heat in the output gas to do the drying. The goal is fuel entering the reactor at 0% moisture, then adding it back in as steam via the preheating "air inlets" to the degree the combustion temps allow.

We also entered the honda in a contest on the DIY site, www.Instructables.com, with a pile of craftsman tools as the award.

Tools are good. We all need more of them. So if you would like, please go vote for us, which is also generally a vote for more gasification in the public eye. the instructable is here:
http://www.instructables.com/id/Convert_your_Honda_Accord_to_run_on_trash/

The instructable has a full copy of the GEK gasifier plans and
fabrication/assembly instructions. It also allows downloading them
as a single pdf, which our wiki can't do.

First Run at Gasifier-Furnace
First Run at Gasifier-Furnace

Ok, I'm new here so skipped a lot of the choices about what I'm doing.

This started with the desire to heat my home with a downdraft gasifier furnace. Here is my first shot:

http://lakeweb.net/gasifier/Gasifier_Furnace.html

I'll clean this page up as I go along. My strong point is a son with a fabracation business and I have been doing electronics all my life. I have started on doing microprocessor interfaces for gasifiers. I have chosen the msp430 for distributed control.

Best, Dan.

JENSEN CHOPPER
Rolf Uhle, Energies Naturals, October 11, 2008

After realizing what you want is a big , clean chunky chip. But for this I don´t need a screw chipper, my old Jensen disc chopper does it perfectly !

That old boy (50y+)cuts neat 12 cm (3 1/2")bits from up to 15 cm diam. fresh hardwood on 20 hp pto and throws them 3m high n.p. It has only 1 blade and a counterweight, has a greedy mechanical 2 cylinder force feeder and still works perfectly after all these years. I built a simple holder for big bags for it and now it fills them o.k..Even very nasty almond and oak branches are drawn through the knives once the force feeder gets hold of the stem.

Of course it is man-fed and does not pick up from the ground which still limits its output and rentability processing pruning branches and crown wood.

If those screw chippers are too expensive and too delicate, why not try one of these. They are easy to build and very strong.

GENEFAG: Mobil Gasifier for Trucks

Last updated February 10, 2008

Mobile Gasifier for Truck
Philippe Raufast, November 20, 2007

As you can see here : http://forum.aceboard.net/12980-1246-27054-0-PROCEDE-GENEFAG.htm
It has already being done here in France, after the first oil shock, by the Calberson trucking company .
The gasifier system was called GENEFAG (generateur fuel air gas). As you can see from the schematic it was of standard Imbert type, running on chopped wood.
Starting fan, igniter, air and gas valves were operated electrically from the dashboard, the driver had various gauges to monitor the system.
You can see that the "packaging" was very neat, using the free space between the truck and trailer to install the "box" containing the whole system.
The smaller Saviem SG2 payload area was a bit shortened .
The Renault truck on the first picture was burning 500 l of diesel to cross France from north to south (1000 km) .
With the gasifier fitted, it was using 200 l of diesel and 1000 kg of wood for the same distance, saving 300 l of fossil fuel.
The payload was 25 tons. I hope you will like it ...
Regards, Philippe.
