Gas cooling - Import export

A Redu-reox incinerator features three reaction chambers for the low NOx combustion of waste streams and fuels with a high organically bound Nitrogen content. In the first reaction chamber a reducing environment is maintained to ensure that any free Oxygen will react with Hydrogen to form water. No Oxygen is left to combine with Nitrogen to form NOx. Complete combustion is achieved in the re-oxidation chamber, after the gases have been cooled in the quench stage. The temperature in the re-oxidation chamber is below 950°C to ensure that any Oxygen reacts with Carbon and Hydrogen and not Nitrogen, to minimize formation of thermal NOx. Key Features Three reaction chambers with staged combustion and intermediate flue gas cooling. First chamber operating under a reducing atmosphere at a temperature above 1250oC. Second chamber to quench the flue gases to about 800°C by either injection of steam or recirculated flue gas. Third or re-oxidation chamber for the post-combustion of remaining waste components at temperatures above 900oC. Key Advantages - Ultra-low NOx combustion of waste streams with high bound Nitrogen contents. – Complete oxidation with all hydrocarbons destroyed – No CO formation – Complete odour destruction – No need for SNCR or SCR deNOx to meet emission limits – Destruction efficiency over 99.999%
