Abstract
A fast pyrolysis heat exchanger system for economically and efficiently converting biomass and other combustible materials into bio-oil. The system employs multiple closed loop tubes situated inside the heat exchanger. As a granular solid heat carrier is deposited at the top of the heat exchanger and caused to move downwardly therethrough, heat is transferred from the tubes to the heat carrier which is then transferred to a reactor where it is placed in contact with the combustible materials.
Claims19
A fast pyrolysis system, comprising:
- a solid heat carrier;
- a multi-tube heat exchanger having a hot air input passageway connected to one end of tubes of the multi-tube heat exchanger and a cold air discharge passageway connected to another end of the tubes;
- an elevator having an input passageway for lifting the heat carrier from a top of the input passageway to a top of the heat exchanger;
- a control probe for sensing a level of heat carrier in the heat exchanger and regulating speed at which the elevator operates;
- an auger located at a bottom of the heat exchanger for controlling movement of the heat carrier through the heat exchanger and for discharging heat carrier from the auger through an output therefrom;
- and
- a reactor comprising a first reactor input in communication with the auger and configured to receive the heat carrier from the auger.
