<p>A Municipal Waste Gasification System whereby Municipal Solid Waste (MSW) an d other forms of waste are converted to useful energy via a close coupled gasificati on process in an artfully designed Waste Conversion and Recycling Vessel (WCRV) that allow s for precise control of the temperature and oxygen content of the batch waste charge while providing for the automatic sorting of all post-gasification residuals. Embodied in the present invention is a Key Accelerant Balancing System (KABS) that precisely controls the temperature in the range of 800-1100.degree.F and oxygen concentration in th e 5-7% range within the WCRV continuously for 12-14 hours yielding overall better efficiency of the conversion of the waste to gas and minimizes pollutants in the present invention. The concrete structure that supports the WCRV doubles as a thermal envelope from which ho t air is drawn from to dry the incoming waste. The residual glass, aluminum and other metallic components of the waste are automatically sized and separated from the ash f or recycling by a logic control system of gravity doors, vibrating super-magnetized grate s, vacuuming, screening and eddy currents advantageously increasing the speed, safety and efficiency of the gasification and automatic recycling of unsorted MSW into energy and marketable raw materials. The gas produced in the waste conversion vessel is conditioned in a unique fuel preparation cell by mixing with ambient air or oxygen and can be used to fir e the waste conversion vessel's heating elements with the excess gas or used to run a ga s fired turbine or boiler to produce electricity with the residual heat used for district heating, or industrial processes.</p> |
