Abstract    The aims of this study are to enhance the performance of a solar chimney power plant (SCPP), investigate utilization of thermal energy storage (TES) and analyze the environmental impact of the SCPP in providence of Isfahan, Iran. To achieve these goals, multi-stage numerical simulations during twenty-four hours of a day are performed in climate condition of Isfahan province (central region of Iran). Isfahan province has proper environmental condition for utilization of SCPP as a source of electricity and the environmental crises during the last decade in Iran have made utilization of green power plants a necessity. Performance enhancement of the SCPP is carried out by improvement in geometrical characteristics of collector and chimney of the SCPP. Considered factors for performance enhancement of SCPP are height, ceiling slop and radius of the collector as well as height, radius and throat shape of the chimney. Then a TES is employed to produce power in the absence of solar radiation in new proposed optimal configurations. In continue carbon dioxide emission and water consumption of enhanced configurations of SCPP are compared with shale gas, coal, hydroelectric and biomass power plants for same output power to investigate environmental impact of the SCPP. Results illustrate that improved collector of the SCPP increases the output power by almost 139% and enhanced chimney of the SCPP improves performance of the power plant by approximately 68.1%. Results also show that the SCPP with the TES would produce power during night hours in a stable range and TES has higher performance in SCPP with optimal proposed configurations. The results confirm that the SCPP is a proper choice for power generation in province of Isfahan (central region of Iran) and the enhanced SCPP with TES improves the output power range and environmental benefits considerably.

چکیده    اهداف اصلی در این پژوهش افزایش کارایی نیروگاه دودکش خورشیدی، بررسی استفاده از ذخیره کننده­ی انرژی حرراتی و آنالیز تاثیرات محیط زیستی نیروگاه در استان اصفهان (ایران) می­باشند. برای دستیابی به این اهداف، مراحل متعدد مدل سازی عددی در طول 24 ساعت شبانه روز در شرایط آب و هوایی اصفهان انجام گرفته است. بهبود عمکرد نیروگاه با ایجاد تغییرات در فاکتور­های هندسی نیروگاه انجام شده است. این فاکتورها عبارتند از ارتفاع، شیب سقف و شعاع کلکتور به علاوه­ی ارتفاع، شعاع و شکل گلویی دودکش. سپس یک نوع ذخیره کننده­ی انرژی حرارتی در حالت بهبود یافته­ی نیروگاه مورد استفاده قرار گرفته است. در ادامه ایجاد آلودگی ناشی از دی اکسید کربن و مصرف آب برای تولید برق در این نوع نیروگاه با چهار نوع نیروگاه گازی، زغال سنگ، هیدرولیک و بایومس در تولید توان یکسان مورد مقایسه قرار گرفته است تا میزان تاثیر مثبت محیط زیستی این نیروگاه مورد بررسی قرار گیرد. نتایج نشان می­دهد که کلکتور بهبود یافته و دودکش بهبود یافته به ترتیب %139 و %68.1 توان نیروگاه را افزایش می­دهند. بر اساس نتایج نیروگاه با وجود ذخیره کننده­ی انرژی حرارتی تولید توان پایداری در طول شبانه روز دارد و ذخیره کننده­ بیشترین کارایی را در نیروگاه بهبود یافته دارد. نتایج همچنین کارایی نیروگاه دودکش خورشیدی در استان اصفهان (مناطق مرکزی ایران) را تایید می­کند و نشان می­دهد که ذخیره کننده­ی انرژی دامنه­ی توان خروجی و فواید محیط زیستی نیروگاه را به طور قابل ملاحظه­ای بهبود می­دهد.
