<p>PURPOSE: An exhaust system of a steam turbine is provided to decrease pressure losses by preventing the dispersing of a flow in an exhaust chamber and improving a function of an annular flow guide. CONSTITUTION: An exhaust system of a steam turbine comprises an inner casing, an outer casing(1), and an annular flow guide(5). The inner casing of an exhaust chamber(12) comprises a turbine rotor(3). The outer casing encloses the inner casing, and forms the exhaust chamber. The annular flow guide is placed in a lower part of a rotor blade of a final stage fixed to the turbine rotor. A flow guide lower part(5d) and a flow guide upper part(5u) are respectively formed at the side and opposite side of an exhaust pipe. The flow guide lower part is longer than the flow guide upper part.</p> |
