A process to combust fuel and oxidant at high efficiency and with low NOx generation even when the fuel has non-uniform characteristics and the oxidant is pure oxygen, wherein fuel and oxidant are first combusted within a high velocity oxidant-rich jet, fuel is mixed with combustion products in a recirculation zone and the mixture is aspirated into the oxidant-rich jet and combusted in a diffuse secondary flame at the periphery of the oxidant-rich jet.

A process for combusting fuel and oxidant at high efficiency with low NOx generation comprising: (A) injecting into a combustion zone fuel and oxidant in an oxidant-rich jet at a velocity sufficient to create a reduced pressure and consequently a strong recirculation zone within the combustion zone

A process for combusting fuel and oxidant at high efficiency with low NOx generation comprising: (A) injecting into a combustion zone fuel and oxidant in an oxidant-rich jet at a velocity sufficient to create a reduced pressure and consequently a strong recirculation zone within the combustion zone proximate the oxidant-rich jet; (B) combusting fuel and oxidant within the oxidant-rich jet to produce combustion products in a jet diluted with oxidant; (C) introducing fuel into the recirculation zone and mixing fuel and combustion products within the recirculation zone; (D) aspirating the mixture of fuel and combustion products into the oxidant rich jet; and (E) combusting the resulting diluted mixture in a diffuse secondary flame at the periphery of the oxidant-rich jet to produce further combustion products.
