A synthetic gas production system

摘要

A synthetic gas production system from high heating value wastes is disclosed. The system comprises a primary waste treatment stage to receive the high heating value wastes and produce a by-product off-gas; and a secondary waste treatment stage coupled to said primary waste treatment stage to receive the by-product off-gas. The secondary waste treatment stage includes a refractory-lined cylindrical chamber having an input port for tangentially receiving said by-product off-gas and an output port. It also includes a DC powered plasma torch proximate the input port within the chamber, the torch receiving a nitrogen-free working as including a mixture of carbon dioxide and oxygen. The plasma torch heats the chamber and the by-product off-gas is converted a synthetic gas, which is ejected through the output port. An oxygen injector and a steam injector is in communication with said refractory-lined cylindrical chamber secondary treatment stage for atomized oxygen and atomized steam injections and a sensor is coupled to said output port of said refractory-lined cylindrical chamber for measuring temperature of said refractory-lined cylindrical chamber and analyzing the content of said synthetic gas. A process controller is coupled to said sensor for receiving data from said sensor and coupled to the injectors for controlling the injection of oxygen and steam.
