Here is one of my projects that I have been working on this summer. I rescued this great old generator and restored it and converted it to run on woodgas.

This is a custom project that I did for the University of Florida for their Farm to Fuel demonstration in Orlando.

I saw this on the Yahoo WoodgasBuilders Group, its an overview of a 75 kw gasifier in Denmark by the Biomass Gasification Group. Its essentially a tar-free combined heat and power system.

Here is an excerpt from their site about their activities:

BGG is working with several gasification processes at our premises:

• The Viking gasifier is an unmanned, automated and essentially tar free gasifier plant with an integrated gas engine for heat and electricity production based on the two stage fixed-bed gasification process and fueled by wood chips. Until now it has produced electricity from wood chips for 3200 hours.
• The LT-CFB gasifier (Low-Temperature Circulating Fluid Bed) is a 500 kW gasifier for difficult fuels with high alkali contents. Until now it has successfully been operated on straw containing more than 12% ash, pig manure and chicken litter. Also its smaller 50 kW predecessor is still operational.
• The Low-Tar BIG gasifier is a new fluid bed implementation of the low tar two stage gasification process intended for large scale two stage gasification plants.

There is a pdf that you can download here that gives some details about their project pictured.
