 An electric generating plant generally includes a plurality of turbines adapted for different steam pressures; for example, a high pressure turbine, an intermediate turbine, and a low pressure turbine. After being passed through from the high pressure turbine to the low pressure turbine to finish rotating work, the steam is finally led into a condenser. The steam then condenses into condensed water and returns to the steam generator. The exit of each high, intermediate, and low pressure turbines is linked with a turbine exhaust system that guides steam to the subsequent stage equipment such as a lower pressure turbine, a condenser, etc. The turbine exhaust system includes an exhaust hood defined between an inner casing covering a turbine rotor and an outer casing further covering the inner casing. The steam that has passed through the turbine blade is delivered to the subsequent stages via the exhaust hood.
A common exhaust hood changes the direction of a steam flow delivered from a turbine from an axial-flow direction to a direction perpendicular thereto in a very short distance. Therefore, exhaust hoods tend to disturb the steam flow and cause pressure loss. In particular, exhaust hoods of high and intermediate pressure turbines have a shorter flow passage than those of low pressure turbines. Further, parts of high and intermediate pressure turbines are made thicker than those of low pressure turbines in order to withstand pressure. Exhaust hoods of high and intermediate pressure turbines are thus more likely to be affected by their inner components such as flanges compared to low pressure turbines.
An example of conventional technologies made in consideration of the above matters is disclosed in JP-2007-40228-A. According to the publication, an annular flow guide is provided at the leading end side of the exit portion of last stage rotor blades. The flow guide rectifies the flow and in turn reduces flow turbulence. The flow guide disclosed in JP-2007-40228-A is an annular flow guide constructed by combining a convexly curved flange with a disk-like steam guide. In contrast, flared annular flow guides are often used in real machines.
Incidentally, flow guides of a low pressure turbine serve as a diffuser for converting kinetic energy to pressure energy. In addition, exhaust hoods of low pressure turbines have less spatial restriction than those of high and intermediate pressure turbines. In regard of this, a flow guide having a vertically asymmetric shape (whose lower side is long) is proposed in the aim of improving diffuser effect (JP 3776580).

An electric generating plant generally includes a plurality of turbines adapt for unlike steam pressures; for example, a eminent imperativeness turbine, an intermediate turbine, and a low press turbine. After being passed through from the high press turbine to the low pressure turbine to eat up rotating work, the steam is last head into a condenser. The steam then condenses into condensed water and returns to the steam generator. The passing of each high, intermediate, and low imperativeness turbines is linked with a turbine exhaust arrangement that guides steam to the subsequent phase equipment such as a lower pressure turbine, a condenser, etc. The turbine exhaust system includes an exhaust hood define between an inner casing covering a turbine rotor and an outer casing far report the inner casing. The steam that has passed through the turbine blade is delivered to the subsequent stages via the exhaust hood. 
 A common exhaust hood changes the guidance of a steam flow delivered from a turbine from an axile - menstruation steering to a direction perpendicular thereto in a very short distance. Therefore, exhaust hoods tend to disturb the steam flow and induce pressure loss. In particular, exhaust hoods of high and intermediate pressure turbines have a shorter flow enactment than those of low press turbines. Further, parts of high and intermediate atmospheric pressure turbines are made thicker than those of depleted pressure turbines in order to withstand imperativeness. Exhaust hoods of high and average pressure turbines are thus more likely to be affect by their inner component such as flanges compared to broken pressure turbine. 
 An example of conventional technologies form in consideration of the above matters is disclosed in JP-2007 - 40228 - A.

In line, flared annular menstruation guides are often used in actual machines. 
 Incidentally, flow guides of a low pressure turbine serve as a diffuser for convert kinetic energy to pressure energy. In addition, exhaust hood of low pressure turbines have less spatial restriction than those of high and intermediate pressure turbines. In regard of this, a flow scout having a vertically asymmetric shape (whose lower side is long) is proposed in the purpose of improving diffuser effect (JP 3776580).
