2 2 Process Flow Organic feedstock at 3”- is fed thru a hopper and through an air lock In the air lock nitrogen purges out the oxygen Blended with steam the feedstock is mixed with f heat As the heat mixes an instantaneous reaction “gasifies” the feedstock breaking it down into it’s basic elemental gases Cyclones separate the product gas and any Char The char is burned in the combustor to generate heat sent to the gasifier Product Gas Advanced Gasification Process Overview Process feedstock is clean woody biomass chips Medium BTU Gas usable directly in the projects gas turbines
