Claim:
1. A method for rapidly converting biomass, the method comprising the steps of: providing a fast pyrolysis unit with a burn enclosure, a combustion chamber and at least one pyrolysis chamber arranged generally concentrically around the combustion chamber, and with a first proximal end of the combustion chamber extending from and in communication with an open end of the burn enclosure, and with a second distal end of the combustion chamber in communication with the first proximal end of the pyrolysis chamber; injecting fuel into the burn enclosure and igniting the fuel to facilitate combustion of the fuel movement through the combustion chamber while simultaneously deoxygenating the combustion chamber, the combusted fuel moving in a first direction from the first distal proximal end of the combustion chamber to the second distal end of the combustion chamber; feeding biomass into the fast pyrolysis unit from a biomass source at a relatively constant rate at a juncture of the second distal end of the combustion chamber and the first proximal end of the pyrolysis chamber; conducting pyrolysis on the biomass in the fast pyrolysis unit to convert the biomass into exhaust gases and entrained matter, the exhaust gases and entrained matter flowing through the pyrolysis chamber from the first proximal end of the pyrolysis chamber in a second direction opposite to the first direction; removing the exhaust gases containing entrained matter from the fast pyrolysis unit; and separating and collecting bio-fuel entrained in the exhaust gases.
