  • Patent number: 8435315
    Abstract: A method and apparatus is described for the efficient conversion of carbonaceous feedstock including municipal solid waste into a product gas through gasification. More specifically, a horizontally-oriented gasifier having one or more lateral transfer system for moving material through the gasifier is provided thereby allowing for the horizontal expansion of the gasification process such that there is sequential promotion of feedstock drying, volatization and char-to-ash conversions.

  • Patent number: 8306665
    Abstract: The present invention provides a control system for the conversion of carbonaceous feedstock into a gas. In particular, the control system is designed to be configurable for use in controlling one or more processes implemented in, and/or by, a gasification system for the conversion of such feedstock into a gas, which may be used for one or more downstream applications. Gasification processes controllable by different embodiments of the disclosed control system may include in various combinations, a converter, a residue conditioner, a recuperator and/or heat exchanger system, one or more gas conditioners, a gas homogenization system and one or more downstream applications. The control system operatively controls various local, regional and/or global processes related to the overall gasification process, and thereby adjusts various control parameters thereof adapted to affect these processes for a selected result.
