  • Method and apparatus for separating particles
    Patent number: 8123838
    Abstract: A method and apparatus for separating particles preferentially accelerates particles to a rotating collector, which then reliably conveys collected particles to a discharge with minimal re-entrainment of the particles in the fluid stream. The collector minimizes energy transfer to the fluid and maximizes separation under conditions of high particle loading, fine particle content, or both. The separator may be operated in any vertical, horizontal or oblique orientation, or within devices whose orientation varies over time.

  • Method and apparatus for reduced emissions fuel combustion
    Patent number: 7670139
    Abstract: A system for combusting carbon-containing fuel includes a reactor 10 for simultaneously supporting oxidation of the fuel and conversion of CO2 within the reactor. A metal oxide or metal is input to the reactor to convert the CO2 to a mineralized CO2 product. A cold trap 44 is provided for capturing exhaust gases from the reactor and returning condensate to the reactor, and a gas pump 50 maintains a desired vacuum or pressure within the reactor and the cold trap. Combustion products may be recycled to increase their energy value.
