Abstract: A dry low nitric oxides (NOx) emissions combustor includes a premixing chamber for mixing fuel and cooling gas and a combustion chamber positioned downstream of the premixing chamber for the combustion of pre-mixed fuel and cooling gas. The combustor further includes a venturi having generally annular walls including converging and diverging wall portions that define a constricted portion and positioned between the premixing chamber and the combustion chamber through which the premixed fuel and air pass to the combustion chamber. The walls defining a passage for cooling gas flow extending axially along the combustion chamber and having an exit for flowing cooling gas to the combustion chamber. A plurality of inlets at the converging and diverging wall portions ingest cooling gas into the passage to produce an impingement cooling effect. A plurality of tubulators disposed downstream of the inlets interact with the cooling gas to produce a turbulated cooling effect. The combustor may be effectively fired over a substantial temperature range to reduce the NOx emissions of the combustor.

Abstract: A method is disclosed for controlling gas turbine operation in response to lean blowout of a combustion can. The gas turbine comprises a pair of combustion cans. The method includes sensing that a first combustion can is extinguished during a full load operation of the gas turbine, adjusting a fuel ratio between the fuel nozzles in each can, delivering a richer fuel mixture to the fuel nozzles nearest to the cross-fire tubes, generating a cross-fire from the second combustion can to the first combustion can, detecting a recovery of the turbine load, and adjusting the fuel ratio to the normal balanced fuel distribution between the fuel nozzles in each can.
