abstract
海底泥の含有エネルギー量を熱量計によって測定するために、最適な試料重量、有効燃焼時間および燃焼回数を検討した。試料として、広島湾中央部において採取した海底泥(含泥率95%、強熱減量12.8%)を使用した。本研究で用いた微量熱量計(測定筒内水量550g)では、最適な試料重量は0.04g~0.2g dryであり、また、燃焼時間は7分間を要した。無機鉱物を多く含む海底泥は、3回の繰り返し燃焼によって、完全にエネルギーを放出させることができた。
abstract
Energy content of marine sediment was measured by a bomb calorimeter. The optimal sample weight, the optimal combustion time and the optimal number of time for combustion were investigated. The mud samples (mud content 95%, ignition loss 12.8%) were collected in the center of Hiroshima Bay. Bomb calorimeters had the optimum range of 0.04g to 0.2g in sample weight and only unreliable values were obtained out of this range. A complete combustion of marine sediment sample took 7 minutes. Energy was completely radiated from a sediment sample, containing much minerals, by repeated combustion.
