* The second phase of incineration should a post-combustion of the flue gas produced by the combustion chamber at high temperature. * 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.

Whether the location is a coastal area : [ ]Yes [X ] No 22. Any other specific requirements: Primary combustion chamber only is required. Solid and inflammable waste products need to be capable of being recovered from the incinerator easily using an automated procedure. This is because the incinerator will be required to operate 24/7. Rotary kiln or moving floor may be considered if deemed practical by the supplier. One initial incinerator is required for a proof of concept project and future orders for the successful supplier, following successful implementation of this project, are likely to be significant.23. It would be most useful if the supplier could send a video of the incinerator in operation or diagrams and pictures to show how it works.
