摘要： PURPOSE:To improve a heat-insulating effect by compact constitution by forming an air layer, which can be ventilated, between the inner plate and sheath plate of the exhaust duct of the gas turbine and each forming an air suction hole to the bottom of the sheath plate and an air exhaust hole to the upper section of the side surface of the sheath plate. CONSTITUTION:A heat-insulating material 18 is set up outside the inner plate 19 of the exhaust duct of the gas turbine, the sheath plates 16 of the exhaust duct are mounted outside the heat-insulating material 18 at regular intervals, and the air layer, which can be ventilated, is formed between both 18 and 16. The air suction holes 22 are formed to the bottoms of the sheath plates 16, and the air exhaust holes are formed to the upper sections of the side surfaces of the sheath plates 16. Accordingly, the temperatures of the heat-insulating material 18 and the sheath plates 16 of the exhaust duct rise, and air is flowed as shown in the arrow 17 from the arrow 20 by a natural convection when air in the air layer expands, and the heat-insulating material 18 is cooled. Heat transmission to the sheath plates 16 from the heat-insulating material 18 is inhibited, and a temperature rise of the sheath plate 16 is reduced.

摘要： PURPOSE:To prevent the generation of combustion vibration even at the time of injecting a large quantity of steam by providing a flow regulating means for regulating the steam flow rates between a compressor steam line and a combustor steam line. CONSTITUTION:A compressor steam line 34 feeds steam between the discharging side of a compressor 11 and a combustor 13. A combustor steam line 35 feeds steam into the combustor 13. A flow regulating valve 33 regulates the steam flow rates between the compressor steam line 34 and the combustor steam line 35. The flow regulating valve 33 determines the distributing quantity between the compressor steam line 34 and the combustor steam line 35 in accordance with the nitrogen oxides density signal 25 from a nitrogen oxide density measuring device 25. Thereby, the flow rate of steam injected into the combustor 13 can be kept at a defined value even when the steam quantity from an exhaust heat recovering device 20 is varied, suppressing combustion vibration while effectively restraining the generation of nitrogen oxide in exhaust gas.
