Keywords:
turbo-compressor package, centrifugal compressor, gas turbine engine, compressor polytropic efficiency, turbine effective efficiency, package integral characteristics, package systematic characteristics, exergy approachAbstract
The methodology of efficiency analysis of gas turbine turbo-compressor package and its systems to select the systematic characteristics and more appropriate mode of its operation at pre-design studies stage while creating new equipment for gas pipelines compressor stations will be finalized in the present work based on the full-scale results of bench and prototype models of the series-produced turbo-compressor package GPA-C-6,3A manufactured by Sumy NPO PJSC and State Enterprise “Ivchenko Progress”. The first part of the work presents the target of research, i.e. modular package designed for line compressor stations and equipped with centrifugal compressor NC-6,3/56В-1,45 providing outlet pressure of compressed gas 5,49 MPa and gas turbine D-336. The main design solutions and the special features of the package which predetermine the package design layout as well as general approach for method development of thermodynamic analysis of the package of container type are considered. Also the work presents the requirements to scope of testing of separate systems including parameters data for operation of centrifugal compressor, gas turbine, auxilliary systems of the package to perform thermodynamic analysis of its operating process when the package runs under conditions of back-to-back test rigReferences
