Abstract
As a diameter of Biocoke is large, the inside structure is different from the outer periphery structure due to heat and pressure distribution in a formation process. A previous study was indicated that compressive strength of Biocoke, which is more than φ20 mm, decrease as a diameter is large. In this study, we conducted combustion tests at 973K by using Biocoke which has different diameter. Results were found in the following. The mass loss rate was proportionalto surface area of Biocoke during flaming combustion. The flaming combustion time and char combustion time were proportional to (V/S)2 respectively. These results are suggested that a combustion behavior of Biocoke which has various diameter (geometric scale) is able to be predict.
