To reliably and effectively heat a balloon-type fermenter in a biogas power generation system.SOLUTION: A flexible plate-shaped heating member including a medium flow path through which a heat medium flows and a base material that holds the medium flow path, is arranged so as to face a fermentation raw material and a digestive juice (content liquid) housed in an internal space of a main body of the balloon type fermenter and to contact an outer surface of a main body. As a result, the heating member can follow an expansion and a contraction and/or a deformation of the main body according to a retention state of biogas, and a content liquid contained in the internal space of the main body can be heated reliably and effectively. In a bio-power generation system equipped with a generator driven by an internal combustion engine that uses the biogas as a fuel, a content liquid contained in the internal space of the main body can be easily maintained at a temperature suitable for anaerobic fermentation by circulating the heat medium warmed by an exhaust heat from the internal combustion engine through the medium flow path of the heating member.SELECTED DRAWING: Figure 17 【課題】バイオガス発電システムにおいてバルーン型発酵槽を確実且つ効果的に加熱する。【解決手段】熱媒体が流れる媒体流路及び当該媒体流路を保持する基材を含む柔軟な板状の加熱部材を、バルーン型発酵槽の本体部の内部空間に収容されている発酵原料及び消化液（内容液）に対して対向し且つ本体部の外表面に接触するように配設する。これによりバイオガスの滞留状況に応じた本体部の伸縮及び／又は変形に加熱部材が追従することができ、本体部の内部空間に収容されている内容液を確実且つ効果的に加熱することができる。バイオガスを燃料として用いる内燃機関によって駆動される発電機を備えるバイオ発電システムにおいては、内燃機関からの排熱によって暖められた熱媒体を加熱部材の媒体流路に循環させることにより、本体部の内部空間に収容されている内容液を嫌気性発酵に好適な温度に容易に維持することができる。【選択図】図１７
