Thermal generator and combustion method for limiting nitrogen oxides emissions by re-combustion of fumes

摘要

The invention relates to a thermal generator comprising a furnace tube ( 2 ) wherein a fuel is burnt, recombustion means ( 14, 15 ) for reducing the nitrogen oxides content present in said fumes and means ( 3 ) for recovering the heat of the fumes resulting from said combustion. The invention is characterized in that recombustion means ( 14, 15 ) are arranged in containment means ( 11 ).
