* The post-combustion chamber should be situated on the top of the combustion chamber so as to re-burn easily the flue gas.
The high content of CO in these gases should permits a re-lighting by simple air injection with the post-combustion burners. This processing is therefore especially well adapted for a treatment on the site.
* The post-combustion of gases should takes place at a temperature of 1,100°C during 2 seconds. The cylindrical form of the post-combustion chamber, combined with Vortex effect in the secondary and tertiary air injection, which have must particularly designed and patented , enabling to assure the achievement of very low hydrocarbon refuse. This should contributes also to the limitation of soot (carbon) in the downstream and of the quantity of solid to be treated in the dust remover.
* The re-light of the combustion by secondary air with the post-combustion burners and the obtained high temperature of the flame allow to finish the combustion of fine carbonized particles. So, there should be small quantity of unburned flying ashes in the downstream of the furnace.
* The design of two post-combustion burners must similar to the combustion burners.
* The post-combustion chamber should fitted with inspection doors so that a periodical cleaning of dust can be achieved.
* The post-combustion should lined with high thermal insulating materials with a thickness of 150 mm of refractory bricks and 85 mm of insulator.
