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.
Claims5
A fast pyrolysis heat exchanger system using a granular solid heat carrier comprising:
- a) a multi-tube heat exchanger having a hot air input passageway connected to one end of the tubes and a cold air discharge passageway connected to the other end of the tubes;
- b) an elevator having an input passageway for lifting the heat carrier from the top of the input passageway to the top of the heat exchanger;
- c) a control probe associated with said heat exchanger for sensing the level of heat carrier in the heat exchanger and for regulating the speed at which the elevator operates;
- d) an auger located at the bottom of the heat exchanger for controlling the movement of the heat carrier through the heat exchanger and for discharging heat carrier from the auger through an output therefrom.
