A centrifugal separator comprises a filtered-gas passageway, a spinner, and a drive mechanism. The filtered-gas passageway has an inlet. The spinner is configured and adapted to rotate about a spinner axis relative to the filtered-gas passageway, and has an inner cavity, a gas permeable outer wall, and a plurality of protrusions that extend radially outward from the gas permeable outer wall relative to the spinner axis. The inner cavity of the spinner is operatively connected to the inlet of the filtered-gas passageway. The drive mechanism is adapted to rotate the spinner about the spinner axis at a rate such that the protrusions prevent particulates from passing through the gas permeable outer wall and into the inner cavity of the spinner and such that gaseous matter is able to pass through the gas permeable outer wall, into the inner cavity, and thereafter into the filtered-gas passageway via the inlet. |

1. A gasifier comprising:
an internal chamber, the internal chamber comprising a main combustion region that is configured and adapted to gasify fuel; a centrifugal separator partially positioned within the internal chamber of the gasifier, the centrifugal separator comprising a gasified-fuel outlet, a spinner, and a drive mechanism, the gasified-fuel outlet having an inlet and being operatively connected to the main combustion region in a manner such that the gasified-fuel outlet is configured and adapted to discharge gasified fuel from the gasifier through the inlet, the spinner being configured and adapted to rotate about a spinner axis relative to the gasified-fuel outlet, the spinner having an inner cavity and a gas permeable outer wall, the inner cavity being operatively connected to the inlet of the gasified-fuel outlet, the drive mechanism being configured and adapted to rotate the spinner about the spinner axis at a rate such that the spinner prevents particulates from passing through the gas permeable outer wall and into the inner cavity of the spinner and such that gaseous matter is able to pass through the gas permeable outer wall, into the inner cavity, and thereafter into the gasified-fuel outlet via the inlet, the drive mechanism comprising a driveshaft and a connected drive motor, the drive motor being positioned external to the internal chamber of the gasifier and to the gasified-fuel outlet, the driveshaft operatively connecting the spinner to the drive motor. |
