Feed line-ultrasonic activated gas injection
Patent
·
OSTI ID:5455059
This patent describes an apparatus for minimizing mass flow rate fluctuations of a particulate solids and gas mixture in the frequency range of about 0.1 to 100 Hertz transported to at least one means for injecting the mixture into a reactor. The apparatus comprises: means for receiving the mixture; means for controlling a discharge flow rate of the mixture exiting the means for receiving the mixture; means for pneumatically transporting the mixture from the means for receiving the mixture to the reactor; means for maintaining a differential pressure between the means for receiving the mixture and the reactor; and means for selectively controlling the mass flow rate of the mixture being transported from the means for receiving the mixture to the reactor including means for injecting a gas at a selected amplitude and ultrasonic frequency into a lower end of the means for receiving the mixture to form an aerated portion.
