法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for designing a top pressure recovery turbine (hereinafter referred to as TRT), and particularly to a method for designing a TRT that can be used under both wet gas conditions and dry gas conditions.

あつた。 The current trend in installing TRTs is to use them under wet gas conditions for two to three years, and then switch to dry gas conditions. By the way, there is a difference of about 30 to 40% in adiabatic thermal head under normal weight flow rates between wet gas conditions and dry gas conditions, and for this reason, the conventional TRT design policy is to optimally design a dedicated machine for each gas condition. was. Therefore, as a matter of course, the size of the TRT was different for wet gas-only machines and dry gas-only machines, and it was necessary to replace it with a completely new TRT when switching from wet gas conditions to dry gas conditions.
この発明の目的は１つのTRT本体にて動翼及

にある。 The purpose of this invention is to provide a TRT design method that allows one TRT main body to be used for both gas conditions by simply replacing the rotor blades and stationary blades.

That is, when operating under wet gas conditions, a wet-only blade is used, and when switching to dry gas conditions, it is replaced with a dry-only blade.
以下、付図に示すTRT組立断面図によりこの
発明を補足説明する。 The present invention will be supplementarily explained below with reference to the TRT assembly sectional view shown in the accompanying drawings.

静翼７を取り替える。 On the other hand, a rotor blade 6 is attached to the rotor 5, and a rotor blade 7 is detachably attached to the inner casing 3. All of the parts except the moving blade 6 and stationary blade 7
The TRT main body parts and configuration have structural dimensions that can be used under both gas conditions, and the moving blades 6 and stationary blades 7 are replaced according to each gas condition.
上述の説明によつて湿式ガス条件から乾式ガス

ビン効率を出し得る。 As explained above, when switching from wet gas conditions to dry gas conditions, there is no need to remove the wet TRT and manufacture and install a completely newly designed dry TRT, which was necessary with the conventional dedicated machine design method. One TRT can be converted to a dry type TRT by simply replacing the rotor and stator blades. Also,
Since the rotor blades and stationary blades are specially designed for each gas condition, it is possible to achieve turbine efficiency comparable to that of conventional dedicated aircraft.
従つて、従来の専用機設計方法では、湿式専用
TRTと乾式専用TRTの２つのTRT本体が必要で

ビン効率を有する、経済的かつ高性能な湿式、乾
式両用TRTと成し得るものである。 Therefore, in the conventional dedicated machine design method,
While two TRT bodies, a TRT and a dry TRT, are required, the present invention requires only one TRT body, and is an economical and high-performance wet type that has turbine efficiency comparable to that of a dedicated TRT under each gas condition. This can be achieved as a dry dual-use TRT.
