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 14000f 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
