INCREASING THE ENERGY EFFICIENCY OF GAS TURBINES IN HOT CLIMATES

Abstract

Technical-economic data of gas turbines depend on ambient temperature: increase of the ambient temperature results decreasing electric power output and electric efficiency of the gas turbines. 28.1 MW gas turbine in Tashkent CHP is investigated for upgrading with including an absorption refrigeration machine. To drive a cooling process the absorption refrigeration machine is analyzed to use a heat of waste gases at outlet of a heat recovery steam generator. Results of calculations for ambient temperature from – 15 ºC to + 45 ºC are presented in the paper. German software EBSILON®Professional was used for simulations.
