An optimized gasification/vitrification processing system having a gasification unit which converts organic materials to a hydrogen rich gas and ash in communication with a joule heated vitrification unit which converts the ash formed in the gasification unit into glass, and a plasma which converts elemental carbon and products of incomplete combustion formed in the gasification unit into a hydrogen rich gas.

Combined gasification and vitrification system

A rotating heat regenerator is used to recover heat from the syngas at it exits the reactor vessel of a waste or biomass gasifier. In some embodiments, three or more streams are passed through the heat exchanger. One stream is the dirty syngas, which heats the rotating material. A second stream is a cold stream that is heated as it passes through the material. A third stream is a cleaning stream, which serves to remove particulates that are collected on the rotating material as the dirty syngas passes through it. This apparatus can also be used as an auto-heat exchanger, or it can exchange heat between separate flows in the gasifier process. The apparatus can also be used to reduce the heating requirement for the thermal residence chamber (TRC) used downstream from the gasification system.

Regenerator for syngas cleanup and energy recovery in gasifier systems

A gasification system method and apparatus to convert a feed stream containing at least some organic material into synthesis gas having a first region, a second region, a gas solid separator, and a means for controlling the flow of material from the first region to the second region. The feed stream is introduced into the system, and the feed stream is partially oxidized in the first region thereby creating a solid material and a gas material. The method further includes the steps of separating at least a portion of the solid material from the gas material with the gas solid separator, controlling the flow of the solid material into the second region from the first region, and heating the solid material in the second region with an electrical means.

Gasification system

The present invention is a vitrification and gasification system that operates at elevated pressures. The system includes a processing chamber having numerous penetrations, and seals for effectively sealing the penetrations to the processing chamber.

Pressurized plasma enhanced reactor and methods for converting organic matter to gas products

An improved active grate consisting of at least two elongated rockers positioned parallel to one and another, each rocker having a lower surface and an upper surface and configured to rotate back and forth about their longitudinal axis. Each individual rocker is further configured to rotate in the opposite direction of the adjacent rockers such that any pair of adjacent rockers alternately forms a void allowing material to pass through active grate when rotating in one direction into a first position, and closes the void when rotated in the opposite direction in a second position. The active grate finds particular utility in a combined gasification/vitrification waste treatment system, where it is used to pass partially oxidized materials from a gasification chamber to a vitrification chamber. The rockers include a coolant loop through the longitudinal axis of the rockers.

Grate for high temperature gasification systems

Pressurized plasma enhanced reactor

The problems of the prior art are overcome by the apparatus and method disclosed herein. The reactor vessel of a plasma gasifier is operated at high pressure. To compensate for the negative effects of high pressure, various modifications to the plasma gasifier are disclosed. For example, by moving the slag, more material is exposed to the plasma, allowing better and more complete processing thereof. In some embodiments, magnetic fields are used to cause movement of the slag and molten metal within the vessel. An additional embodiment is to add microwave heating of the slag and/or the incoming material. Microwave heating can also be used as an alternative to plasma heating in a high pressure gasification system.
