Reducing Nox Emissions Using The Gas Reburning Process

The reburning process is a secondary NOx control technology that consists in using fuel as are reactant that will react with NO molecules. The reaction is brought about by injecting a set amount of fuel into the downstream of the primary combustion at a high temperature. If this process is chemically complex, it is technically rather simple to implement and will be compatible with a wide range of existing installations. This article presents Gas de France's abilities on the reburning process. It is illustrated by an industrial partnership with a glass manufacturer. The demonstration operation has been carried out on part of a float furnace where a NOx reduction of 70% was obtained.
