摘要： In a gas turbine, an exhaust casing and an exhaust chamber are connected by an exhaust chamber support that can absorb thermal expansion, and the exhaust chamber and an exhaust duct are connected by an exhaust duct support that can absorb thermal expansion. An insulator is mounted on an outer peripheral surface of the exhaust chamber, and the exhaust chamber support and the exhaust duct support are disposed outside the insulator in the form of a plurality of strips. Because the thermal stress at a connection portion of the exhaust chamber is reduced, the durability is enhanced.
