We developed the solid biomass fuel (hereinafter refer to as Bio-coke: BIC) and studies to use as a replacement for coal coke advance. Above all, a proof examination of the gasification melting furnace is pushed forward, and the elucidation of the combustion behavior of BIC in the gasification melting furnace is important. In this study, we produced BIC in different heating temperature from green tea and torrefaction process. And we execute specific surface area and the combustion experiment using torrefied BIC (hereinafter refer to as Bio-coke: T-BIC). Results are found in the following. (1) As the torrefaction processing time is long, the specific surface area grows. But, T-BICs of producing temperature 423K and 443K have maximum specific surface area. (2) As the torrefaction processing time is long, the combustion time is long. (3) As the specific surface area is large, the combustion rate of flaming combustion periods is small. The combustion rate of char combustion periods is constant regardless of the specific surface area.
