RECOMBUSTION PROCESS FOR REDUCTION OF NOX FROM FLU GASES RESULTED BY PRIMARY COMBUSTION IN OVEN, AND APPARATUS FOR THIS PROCESS

摘要

The present invention relates to a process for reducing nitrogen oxide times contained in flue gas discharged by primary combustion in an oven. The invention also relates to an apparatus for carrying out the process. In the process of the invention, the heat injects a second-order fuel into the furnace re-combustion zone in at least two associated jet jets, one of which is viscous high-pressure and the other viscous is low-pressure. with an inlet (2, 2 ') suitable for supplying different pressures with a single-core fuel.
