چکیده

در تحقیق حاضر، یک سیستم تولید همزمان توان و حرارت متشکل از پیل­سوختی اکسید جامد و گازساز زیست توده معرفی شده است. در این سیستم از لوله­های حرارتی برای انتقال حرارت از محفظه پس­سوز به بستر گازساز استفاده شد. نتایج حاکی از آن است که زمانی­که دمای پیل سوختی افزایش یابد، بازده سیستم افزایش و بازگشت ناپذیری­ها کاهش می­یابد. در چگالی جریان A/m4000  و دمای خروجی پیل­سوختی °C850، بازده­های گاز سرد گازسازی زیست­توده و اگزرژی به ترتیب 74/91% و 79/45 % بدست می­آید. همچنین هیدروژن 35% از ترکیب گاز سنتز خروجی از گازساز را به خود اختصاص می­دهد
