ABSTRACT:
A method and system for continuous incineration of solid waste, directed to reducing formation of pathogens (such as dioxins) during incineration by inducing rapid combustion in an oxygen-rich environment. Waste may be shredded first. Waste is then dispersed widely across a first combustion chamber in which it undergoes incineration into ash and gas. Alternative embodiments for continuous removal of hot ash are disclosed. Gas is encouraged to travel a spiral path into a second combustion chamber, in which further incineration occurs. Gas travels through the second combustion chamber also in a spiral path, and is cooled in a quench tube. An evacuator means, advantageously a large fan, draws air through the system continuously during combustion, encouraging flow of waste through the system and replenishing oxygen available for rapid combustion.
