يهدف هذا البحث إلى دراسة تأثير حجم المخمر على المتطلبات الحرارية اللازمة لإتمام عملية التخمير وذلك بغية الوصول الى الحجم الاقتصادي الأمثل له. تمت الدراسة على مخمر دفعي مغلق مزود بلاقط شمسيّ, حيث جرى قياس المتطلّبات الحراريّة له, وعند نفس الشروط المحيطة تم تغيير حجم هذا المخمر من أجل تحديد مقدار التغير النسبي للمتطلبات الحرارية اللازمة بهدف الحصول على حجم مخمر يتطلب أقلّ كمية من الطاقة ضمن الشروط الحارة للتخمير اللاهوائي.
This research aims to study the effect of the digester size on its thermal requirements in order to reach the optimal economic size to him.
Where were studied a batch closed digester with solar collector, where he was measuring a thermal requirements at the same ambient conditions with the change of the size of this digester, in order to note the relative change of the heat requirements, and to get the optimal size that requires the least amount of energy in thermophilicanaerobic digestion.
