Abstract:
Industrial gas turbines widely use in order to power generation in power plants and pressure boosting in oil and gas umping lines. The industrial gas turbines are very expensive to produce and manufacture. So, in recent years, Aeroderivative gas turbines are taken into consideration. For this propose, the gas generator part of the aero engine has been separated from the core and with some changes it has been converted to industrial gas turbine.one of the advantages of this work is that the aero engine gas generator is more efficient and this benefit leads to increasing the gas turbine cycle efficiency.
In this work, a two spool aero engine and a three spool one have been studied. For this propose, GE90 and Trent800 aero engines are used to design industrial gas turbines. GE90 is a two spool aero engine and Trent 800 Is a three spool one. In order to modeling the aero and industrial engines the GasTurb software has been used. Different methods can be used to convert the aero engine to industrial. The application of these methods depends on various factors such as aero engine application, aeroderivative engine application, facilities and etc. In this study to convert the GE90 aero engine four methods have been tried and for Trent800 there are 2 methods. One of the most important changes is removing the fan. Now for improving the aeroderivative engine one or two compressor stages can be replaced it. For the power generation the low pressure turbine of aero engine or multi stages of a free power turbine can be used.
Various design of aeroderivative engines have been discussed and their performance have been compared to each other. Due to applied changes and the used methods, the most available shaft power from the aero engines is 51.17 MW for the GE90 and it is 60.68 MW for Trent 800.
