Cyclone separator

Patent ·
OSTI ID:6006474

A cyclone separator is described comprising: (a) a combustion chamber having a cylindrical member closed off by an upper end wall; (b) a fuel inlet tangentially formed in a lower portion of the combustion chamber through which a pressurized stream of carbonaceous material is fed; (c) an air inlet tangentially formed in a lower portion of the combustion chamber above and at an inclined angle to the fuel inlet through which a pressurized stream of hot air is fed; (d) an outlet formed in the upper end wall through which the ash is removed; and (e) an outlet tube coaxially positioned within the combustion chamber which extends out through the upper end wall. The tube has at least one peripheral opening formed which requires an angular turn by the spirally circulating combustible gas in order to enter the tube. The angular turn assists in separating the combustible gas from the ash whereby essentially ash-free gas exits the combustion chamber through the outlet tube.
