| چکیده | ||
| The temperature of the exhaust gases from simple gas turbines is high, and therefore, gas turbines have low thermal efficiency. Also, high ambient air temperature reduces the output power and thermal efficiency of the cycle. This paper examines a system that uses a heat recovery boiler to recycle exhaust gases and produce steam. Steam is produced in a double-pressure boiler. Low-pressure steam is introduced into the lithium bromide single-acting absorption chiller to cool the air entering the compressor, and high-pressure steam is injected into the combustion chamber of the gas turbine. The main purpose of this paper is to study and analyse (energy, exergy and environmental) gas turbine system with steam injection with cooling of the inlet air. The gas turbine cycle of the Zahedan gas power plant was modelled based on Heat Recovery Steam Injection (HRSG). Then energy and exergy are carried out. Also, the effect of steam injection and inlet air cooling on heat efficiency, output power, fuel consumption, exergy efficiency and total system price was studied and presented. The results showed that with a 10% spray of steam inside the combustion chamber, the output power increased by 11.03% and the thermal efficiency of the cycle increased from 24.4% to 26%. | ||
