<p><P>PROBLEM TO BE SOLVED: To provide a gas turbine combustor capable of stabilizing combustion according to a change of a combustion load in the gas turbine combustor to thereby control the generation of a nitrogen oxide, and to provide a gas turbine and a method of controlling the gas turbine combustor. <P>SOLUTION: The gas turbine combustor 6 includes: a plurality of premixed combustion burners having a premixing chamber for forming a premixed gas by mixing fuel and air flowing in from fuel control valves 11a, 11b and 11c; and a fuel controller 12, which pre-stores a distribution amount reference value of fuel for each premixing chamber corresponding to a fuel temperature calculation value of a combustion gas G and a distribution amount correction value corresponding to a state quantity of air flowing in the premixing chamber, which calculates the combustion temperature of the combustion gas G from the state quantity of the gas turbine 7 and measures the state quantity of air flowing in the premixing chamber, which corrects the distribution amount reference value by the distribution amount correction value, and which controls the distribution amount of fuel for each of the fuel control valves 11a, 11b and 11c on the basis of the calculation result and the measurement result. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
