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.
