Abstract

The paper aims for parametric sensitivity analysis for
the performance of the steam jet ejector in a steam power plant.
This paper contains a one-dimensional mathematical model for
the steam jet ejector major components; the chest chamber, the
mixing chamber and the diffuser. It presents the entrainment
ratio as a function of operating parameters. The developed
equations were solved iteratively for parametric evaluation and
latter, for studying the effect of the operating parameters on the
efficiency of the steam jet ejector. The efficiency of the ejector
will reach its maximum when the compression ratio and the
driving pressure are kept at minimum. In case of a positive
incremental increase of the driving pressure, a larger size of
ejector is required. More over, an optimum temperature ratio of
a slight fraction over one needed to be maintained for best
working conditions. With these deductions, this research paper
will provide a temporary optimization for the efficiency of a
setup ejector in case of off-design parameters.
