Fatboy Gasifier in the UK
I have been working with David Friese-Greene from the UK on developing the Fatboy Gasifier for the UK and Indian markets. David is involved in the UK with the Soil Fertility Project which is working with SCAD who is a Social Change and Development non-profit non-governmental organisation in Tamil Nadu, India.
After trialling the UK’s first Fatboy Gasifier David hopes to make the units available in the UK for sale, with the income from these sales he hopes to develop a project to bring the units design to India for local manufacture and roll out into grass roots village applications. We have also been discussing a roll out into area’s of Africa once the Indian project is under way.
I am extremely excited to see all my years of development work now evolving into this expanding open source project. If you are interested in getting involved, supporting our projects or making your own unit, please contact myself here >>>>
I hope to get David’s updated plans uploaded soon.
These are my three major versions to date.
Update from David.
“Searched out some 25% moisture feedstock and look what happened – she worked beautifully and clean. Did a second burn and had a barbie, same result – and we danced around the fire!
Just a quick note on feedstock. While 35% moisture will run in the unit it will run much slower, at 25% or lower you are in the desired range for this style of system. The unit also needs a uniformed feedstock like wood chip or mulch as this allows air flow from the bottom primary air which feeds the hot char bank as it travels downward, this puts the above hot freshly charred biomass into a smokey oxygen-less environment, so it stops it’s combustion. A uniformed feedstock also stops any sparks or embers from dropping to the bottom of the unit and starting to char there, which would put the above un-charred biomass into an oxygen-less environment, not what you want to happen. You can add some chunky dry matter like old beef bones or chicken bones, you can horizontally layer dry branches up to 20mm thick as long as the gaps around them are filled with dry chip of mulched material. I try to avoid large amounts of leaf matter and feed stocks like hay or chaff as these can produce too much volatile off-gas that can over whelm the unit and you will lose your volatile gas combustion and just produce masses of white smoke.
