| Summary: | 碩士 === 國立臺灣大學 === 機械工程研究所 === 81 === The paper is study the combination of steam ejector with back
pressure steam turbine cogeneration system . From steam ejector
character and energy saving.recovery view point , the optimum
is being researched . And the different within steam ejector
and traditional compressor using in back pressure steam turbine
co- generation system will be found . The result short note in
below : (1) In thermodynamic first law and one-dimension
assumption , if use the steam of water as working fluid in
ejector , low effeciency will be found . If not se a low price
steam or a waste steam , using this method for air-condition is
not profit . (2) In Heikel factor analysis , from traditional
compressor and steam-jet using in back pressure steam turbine
system relative view point , low steam turbine effeciency can
given more good recovery heat energy .
