چکیده | ||
امروزه مزایای اقتصادی، زیستمحیطی و فنی به عنوان یک رویکرد مناسب برای سیستمهای تولید همزمان بوده و رویکرد استفاده از گرمای اتلافی برای این سیستمها ارزش خود را بیش از پیش نشان میدهد. در این مطالعه سیستم تولید همزمان متشکل از چرخه برایتون فوقبحرانی دیاکسیدکربن، چرخه رانکین آلی، الکترولایزر غشاء پروتونی و واحد اسمز معکوس است. ابتدا تحلیل انرژی و اگزرژی روی سیستم پیشنهادی انجام پذیرفته است، در ادامه روی این سیستم پیشنهادی مطالعه پارامتری انجام شده و در نهایت از دیدگاه بیشترین توان خالص چرخه، مورد بهینهسازی قرار گرفته است. نتایج بهینهسازی نشان میدهد که مقادیر توان خالص تولیدی، بازدههای حرارتی و اگزرژی، هیدروژن تولیدی و آب شیرینشده به ترتیب 252366 کیلووات، 1/43 درصد، 37/58 درصد، 13/12 کیلوگرم بر ساعت و 52/55 کیلوگرم بر ثانیه میباشد. همچنین سیستم تولید همزمان پیشنهادی، دارای نتایج بهتری از دیدگاه بازده قانون اول نسبت به مطالعه پیشین میباشد. | ||
