Abstract:
An apparatus for combusting fuel, the apparatus comprising:at least one combustion chamber wall forming a combustion chamber, primary means for forming a premixed fuel and primary oxidant mixture which is so fuel-enriched that the premixed fuel and primary oxidant mixture cannot burn under fuel and primary oxidant conditions within a first zone of the combustion chamber; andsaid at least one combustion chamber wall having a plurality of ports peripherally surrounding said inlet, and secondary means for introducing a second supply of oxidant into the combustion chamber through said port and forming a plurality of secondary oxidant jets that draw the premixed fuel and primary oxidant mixture through the first zone and into a second zone of the combustion chamber combust the premixed fuel and primary oxidant mixture in the second zone and form a stabilized combustion flame anchored about a periphery of the secondary oxidant jets.
