Abstract
In this invention a cyclonic separation method and apparatus discharges particulate solids and gaseous fluids into a separation vessel from a discharge opening of a central conduit and withdraws separated gaseous fluids from the separation vessel with a recovery conduit having an inlet located below the discharge opening. Recovery of separated gases using cyclonic separation is improved by the specific location of the recovery piping inlet which reduces the entrainment of fine particles with the gases.
