The invention is directed to an optimized two-chamber eductor based incinerator system. The two-chamber optimized incinerator system includes a primary and a secondary combustion chamber, the system having a single fuel fired burner located in one of the secondary combustion chamber, or the eductor. The system also includes an eductor connecting the primary combustion chamber to the secondary combustion chamber, the eductor creating a recirculation flow through the first and the second combustion chambers.
