Re: [Biofuel] Glycerine as fuel
Hello Balaji, Hello Bill, in spite of having a large supply of natural gas in Argentina, and cheap, there are still many places where thereare no distribution lines. In our case at the North West of the country there is a large availability of biomass, which we would like to consider for gasification: heat for our own chemical processes, for generation of our own consumption of electricity and probably for sales of electricity to the grid, and small units for poor,far located towns. Bill, can you give the name and adress, phone, e-mail, etc. of the company that supplied the biomass gasifier in Alabama? Balaji, can you give names,etc. of other manufacturers of gasifiers? Thank you very much.

We have installed a 1100 kg/hr gasifier using adual fuel burner burning Heavy Furnace Oil or Producer Gas ora combination of both to provide process heat for a Hydrofluoric Acid Plant. We have recently comissioned a 650 kWe captive power plant in a dairy unit near Chennai, Tamil Nadu, using 100% gas engines from Cummins India, and we have two grid connected systems - a 200 kWe vilage electrification project funded by UNDP and a 1250kWe Power Plant wheeling the power over the State Utility grid to its sister unit300 km away.Most of the above units use Prosopsis Juliflora, for which many thanks, since it is an import from South America.

Re: [Biofuel] Glycerine as fuel
Bill, One would imagine that a gasifier would reduce all components of the glyc cocktail to syn gas and char. Gasification is a novel thought to reducing that waste/co-product to nill though. No addition of anything. No chemical refining. No new energy inputs. No disposal problem with the remaining crude glycerol. A standard ratio/mix of biomass to cocktail might be just the ticket. Here is a gasifier that we've been eying for a couple of years now. http://www.alternateheatingsystems.com/woodboilers.htm It's the only one we've seen that might fit the ticket.
