چكيده فارسي :
In this study, proposing an augmentation of solar thermal system for a heat and power cogeneration power plant, enviroeconomic analysis was carried out. The model of solar-thermal power generation utilized the preheated steam from Linear Fresnel Solar Collectors (LFC) into the boiler and then to back pressure steam turbines. This compound solar installation gained the sun angles and weather data of city of Yazd in Iran. Then, a common simulation examined the effects of a 2 MW augmented solar plant to a 43 MW cogeneration system while generating the power. Then, to indicate the advantages of solar energy application in potent regions, the environmental and economic effects of solar system in overall power plant were analyzed. Enviroeconomic analysis was included of Greenhouse Gas (GHG) emissions and its costs were determined. Similarly, to compare a green renewable energy source and a fossil-fuel one, the calculation was conducted on cogeneration system as well. In conclusion, the role of solar-thermal system in fuel saving as well as in 93% reduction of GHG emissions was emphasized, while the cogeneration system with negative impact of 310% CO2 emission was presented as an environmentally-irresponsible energy system.
