Abstract

The present invention is a regenerative gas incineration apparatus having three heat regenerators containing refractory heat exchange material. Gas is cycled through the regenerators first in one direction, then in another. The regenerators are each connected to combustion chamber having an air-fuel system and at least one burner. A system of valved ductwork is utilized to direct gas to be processed into and upwardly through a heating first regenerator into the combustion chamber, downwardly through a cooling second regenerator and exhausting the processed gas to the atmosphere. The temporarily idle third regenerator is purged of partially treated gas remaining from a previous cycle and this gas is directed to the combustion chamber. The flow of the gas through the system is periodically changed enabling the heat recovered by cooling regenerator in the previous cycle to be used to heat incoming gas in the next. Each of cycle results in the former heating regenerator to become the idle regenerator, the former cooling regenerator to become the heating regenerator and the former idle regenerator to become the cooling regenerator.
