Thermal characteristics of oil palm fibre treated with cassava starch solution for possible use as insulation material
Ekoja, M, Edeoja AO, Nwankwo K
The search for local substitutes for imported insulation materials used in local ovens of temperature range (450 °C – 1600°C) and other heat transfer system has motivated this work. At the same time, human agricultural activities have highly generated a lot of biomass materials that constitute environmental hazard. These biomass materials can be processed into useful alternative materials such as those used in thermal insulation. Oil palm fibre and cassava starch are common examples. The thermal characteristics of oil palm fibre treated with 0.20 w/w cassava starch solution (CSS) were investigated. The Maximum Use Temperature of the oil palm fibre treated with CSS was determined using the ASTM C411 recommendation. The mean values of the specific heat capacity, density, thermal conductivity, thermal diffusivity and maximum use temperature were determined as 27.09523 kJ/kg°C (67 °C), 275.69 kg/m3, 0.159 W/m K, 2.129 x 10-8 m2/s (at 67 °C), and 320 °C respectively. The determined characteristics show that the oil palm fibre board is suitable for use as an insulation material in low temperature oven application and thermal solar processes.
