초록

A NOx reduction burner system and process. Fuel modification and fuel rich reactor zone gases are brought together with products from a fuel lean reactor zone in a low temperature burnout and NOx reduction reactor zone. The fuel modification fuel rich reactor stabilizes combustion through recirculation of hot gases to the reactants. Nitrogenous species decay reactions in the fuel rich zone controls the production of NOx. The nitrogenous species from the fuel rich zone and the NOx from the fuel lean zone then react in the burnout zone at an optimal temper...

1. A combustion and emissions control system of apparatus comprising a first reaction chamber, means for injecting into the first reaction chamber fuel and air in amounts which produce a first mixture having a total fuel to air equivalence ratio which is sufficiently greater than one to cause combustion and nitrogenous species decay reactions over a residence time and temperature which are sufficient to produce first combustion products comprising partially oxidized fuel, decayed levels of nitrogenous species, nitrogenous NOx reducing species and nitroge...
