Abstract

PURPOSE: To enable NOx to be efficiently decreased to within a permissible range in accordance with an operating condition of the generating plant, by jointly using three methods of steam injection, water injection and catalyzer denitration in the waste heat recovering combined-cycle turbine.
CONSTITUTION: A combustion gas which has completed the work in a gas turbine 4 is fed to an exhaust gas boiler 6 to generate a steam and this steam drives a steam turbine 9. In such a plant as in the above, a denitration device 16 is provided in the boiler 6 and supplied a liquid medicine like ammonias from liquid agent injection pump 17 through a flow regulator valve 18. While a combustor 3 is supplied a water through a flow regulator valve 23 from a water pump 22 also injected a steam through a flow regulator valve 24 from a low pressure evaporator 12 in the boiler 6. Here those of the flow regulator valves 18, 23, 24 are controlled through a NOx controller 19 on the basis of each output from a pressure detector 25 for the low pressure evaporator 12, a NOx concentration detector 26 and a turbine output measuring unit 40.
