Abstract

A method for low NOx combustion, without premixing of fuel and air prior to passage to a combustor, is provided wherein a fuel is injected into a reaction zone via an eductor thereby inducing an air flow and producing a fuel-rich mixture. The fuel-rich mixture is reacted and produces partial reaction products plus heat. A portion of the heat is to transferred to a cooling air stream and the cooled partial reaction products are brought into contact with the heated cooling air stream for combustion. Increased injection of the fuel results in an increased induction of the air flow.
