Abstract

PURPOSE: To reduce the amount of NOx contained in exhaust gas discharged from a combined plant, by keeping load of gas turbine low and recirculating a portion of exhaust gas of the gas turbine to a waste-heat recovering boiler at the time before steam turbine is started in starting operation of the plant and at the time after the steam turbine is stopped in stopping operation of the plant.
CONSTITUTION: The combined plant shown in the drawing comprises a gas turbine 12, a waste-heat recovering boiler 2 incorporating a denitrating means 23 for generating steam by the heat of exhaust gas of the gas turbine 12, and a steam turbine 33 driven by the steam generated by the boiler 2. Here, there is provided a steam blowing pipe 61 which is branched from steam outlet pipe 31 of boiler 2 and connected to blow tank 63. This blow pipe 61 is provided with a pressure control valve 62, which is controlled by pressure regulator 64 to keep steam pressure at the outlet of boiler 2. By this control system, by-pass damper 17 is kept open almost to its full extent and inlet damper 16 is kept open to its full extent during low-load operation of gas turbine 12.
