PROCESS AND APPARATUS FOR TRANSFORMING WASTE MATERIALS INTO FUEL

摘要

A process to transform solid waste into fuel by adding water and heat to provide no more than 350 BTUs/lb of the weight of the solid waste for no more than 85 minutes. Such a process transforms the solid waste into fuel in a process time of not greater than 85 minutes. The system uses a pressure vessel; a condenser tank to permit selective addition of water to and evacuation of steam from the vessel; a heater to increase the temperature of the vessel; a vacuum pump to selectively reduce pressure within the vessel and to help evacuate steam from the vessel to the condenser tank; and a water pump to selectively add water from the condenser tank to the interior volume of the vessel. A method for converting solid waste into fuel includes loading the solid waste into a rotating pressure vessel and transforming the solid waste into fuel by adding water; reducing pressure; adding heat; and then evacuating steam. The contents are evacuated from the pressure vessel. At least some of the contents are fuel.
