| Abstract: | Among
many available retrofitting technologies to improve power generation capacity
and efficiency of simple cycle gas turbine, inlet air cooling (IAC) and steam
injection gas turbine (STIG) are considered most effective ways to modify an
existing simple cycle unit. In this study, a simple cycle generation unit is
considered as base unit and STIG and IAC features are sequentially retrofitted
to the system. Retrofitting of simple cycle combined with IAC and STIG has been
found to boost power output from 30 MW to 48.25 MW, while generation efficiency
can be increased from 29.9% to 33.4%. Exergy destruction rate per MW of power
output reduces for combustion chamber, compressor and HRSG, while increases for
gas turbine for retrofitted cycles. |
