Abstract: A method and system for the conversion of waste into energy in a sealed system where combustion does not take place and the operating pressure prior to the inlet of the steam or power generating equipment is maintained below atmospheric pressure. Destruction of the RDF (refuse derived fuel) is accomplished by subjecting the RDF to a high temperature environment under controlled conditions in a purpose designed and built reactor. The high temperature environment, <5000° C., is achieved through the use of one or more non-transferred plasma torches for generation of plasma gas. The plasma gas exiting the torch and provides the thermal energy for the continual gasification of metallurgic coke configured as a carbon bed in the lower part of the reactor, which acts as a thermal catalyst and this provides the thermal energy for the gasification process.
Abstract: A thermal reactor for producing usable heat energy by destroying waste including a vessel wherein organic waste upon entering said vessel gasifies as it falls onto a carbon bed and is transformed into a synthesis gas with high heat and kinetic energy that can be harnessed to produce electricity. Inorganic waste upon entering melts as it falls onto the carbon bed and exits via slag ports to form an inert slag. Because there is no oxygen present in the gasification zone, the waste is not combusted and neither furan or dioxin are formed. The waste includes either prepared refuse derived fuel (RDF) or unprepared raw waste or a combination thereof.
