Ignition and combustion characteristics of Bio-coke (BIC, highly densified biomass briquette) in high temperature air flow have been investigated. In the present study, ignition behavior is observed, and the mass loss rates for flaming combustion and surface combustion are measured. The experimental results showed that the surface ignition precedes gas-phase ignition in the case of high temperature air, while surface ignition and gas-phase ignition simultaneously occur in the case of low temperature air. Consequently, it is suggested that the temperature distribution inside BIC, i.e. the preheating condition which is correlated with air temperature and air flow rate, strongly affects on the ignition modes and subsequent combustion rates.
