| چکیده | ||
| در مطالعۀ حاضر، یک سیستم تولید سهگانه پیشنهادی بر اساس پیل سوختی اکسید جامد با ریفُرمر خارجی، سیستم تبرید گَکس و بازیاب حرارتی از دیدگاه ترمودینامیکی و اگزرژواکونومیکی مورد بررسی قرار گرفته است. از یک ریفُرمر خارجی برای تبدیل سوخت د یمتی لاتر به هیدروژن، جهت مصرف در واکنشهای الکتروشیمیایی پیل سوختی استفاده شده است. تأثیر پارامترهای اساسی )ضریب بهرهوری سوخت و دمای جریان ورودی به آند( بر روی چندین متغیر )بازده انرژی و اگزرژی، تخریب اگزرژی و هزینه واحد توان تولیدی( مورد بررسی قرار گرفته است. بر اساس نتایج، بازده انرژی سیستم پیشنهادی از بازده پیل سوختی به تنهایی بیش از 38 % بیشتر است. بالا بردن دمای جریان ورودی به آند موجب نزولی شدن روند تخریب اگزرژی در پس سوز و پیل سوختی میشود در حالی که بر روی بازیاب حرارتی تأثیری معکوس دارد. هزینۀ واحد توان تولیدی تحت شرایط مُعیّن برابر با $/ 23/51 GJ است و با افزایش ضریب بهر هوری سوخت و یا افزایش دمای جریان ورودی به آند روند نزولی دارد. افزایش ضریب بهرهوری سوخت موجب افزایش بازدههای قانون دوم به میزان 12 % میشود. تأثیر افزایش دمای جریان ورودی به آند بر بازده های قانون دوم نیز مثبت است ولی نسبت به افزایش ضریب بهرهوری سوخت پایینتر بوده و بازدهها 8% افزایش مییابند. | ||

| چکیده [English] | ||
| In the present study, Exergoeconomic analysis of a combined solid oxide fuel cell with a gas turbine, a generator-absorber heat exchanger and heating process heat exchanger for heating, cooling and power production as a tri-generation system is conducted. An external steam reformer is applied to convert di-methyl ether as oxygenated fuel to hydrogen for the electrochemical process of the solid oxide fuel cell. The influence of the primary design parameters (fuel utilization factor and anode inlet temperature) on several variables (energy and exergy efficiencies, exergy destruction and unit costs of the power) are examined. Results show that energy efficiency of proposed system is 38% higher than standalone solid oxide fuel cell. It was found that the maximum exergy destructions occurred in afterburner, solid oxide fuel cell and recuperator. An increase in anode inlet temperature leads to reduction of exergy destruction in afterburner and fuelcell. Unit cost of power is equal to 23.51 $⁄GJ and decreases with an increase in fuel utilization factor or increasing of anode inlet temperature. Increasing of utilization factor will increase all exergy efficiencies by 12%. The effect of increase in anode inlet temperature on exergy efficiencies is positive but compared with the other parameter is lower and will increase them by 8%. | ||
