Abstract

PURPOSE:To decrease quantity of water used for reduction of NOx in a generating plant using a gas turbine and a steam turbine by cooling a part of exhaust, after its going through a denitrating device, to a predetermined level and sending its predetermined quantity into an intake duct. CONSTITUTION:A part of air and exhaust gas is compressed by a compressor 2, a turbine 4 is driven with high temperature gas from a combustor 3, waste heat is collective 11. A part of steam and CO2 contained in this exhaust is returned to an intake duct by a blower 8 through a cooler in order to use it for reducing NOx. Since a blade is eroded when this temperature falls below the dew point, quantity of cooling water is regulated by an output of a thermometer 10. Since concentration of NOx is changed according to ratio of flow of exhasut, it is controlled by a flow control valve 12. In this case, either desulfurizing device is used or fuel, not including sulfur, is used because there is a danger of errosion due to low temperature.
