To improve the efficiency of the compressor stations, the heat recovery of gas exhaust has been applied using the heat recovery of the steam generator (HRSG). Three types of HRSG as a single, dual, and triple-pressure combined cycle with a reheat system have been investigated. In this regard, the fuel heating and also preheating of feed water using solar energy have been evaluated. Due to the application of solar power tower technology to achieve 1000ºC temperature for hybridization in conventional fossil-fired power, it has been considered. Also, exergoeconomic and exergoenvironmental analyses of using solar energy and heat recovery of the gas exhaust have been evaluated. The arrangement of the gas station is based on (3+1) gas turbines. In this regard, an HRSG system and a steam turbine were used for three gas turbines in the Kashan pipeline station to recover of hot gas in the outlet of the gas turbine. https://gpj.ui.ac.ir/article_27017_01d3eb570a23d0bd3dd7f3d03293e7c0.pdf
