CONTROL DEVICE OF GAS TURBINE PLANT, GAS TURBINE PLANT AND DENITRATION CONTROL METHOD OF GAS TURBINE

摘要

PROBLEM TO BE SOLVED: To more accurately calculate an ammonia amount to supply to a denitration device.;SOLUTION: A gas turbine plant 10 comprises a gas turbine 12 provided with a combustor 22 to generate a combustion gas and a turbine 24 driven by the combustion gas and a denitration device 16 to remove NOx contained in an exhaust gas exhausted from the turbine 24 by ammonia. The control device 18 of the gas turbine 12 calculates a Nox generation amount contained in the exhaust gas based on a combustion load command value where the temperature of the combustion gas at the inlet of the turbine 24 is made dimensionless and calculates an ammonia amount to supply the denitration device 16 based on the calculated Nox generation amount.;COPYRIGHT: (C)2015,JPO&INPIT
