Abstract

In the present study, the combustion flames of pulverized woody biomass in a high-temperature air stream were investigated on the physical properties such as pulverized size and air flow rate, comparing those of fuel gas jet flames. Wood -pellet and pulp and were used for pulverized biomass fuels, and propane was used for gas fuel. The effects of the fuel on the ignition temperature and ignition delay time were examined. It was shown that the decrease of the diameter of pulverized woody biomass reduces the ignition delay time. The results suggest that the ignition characteristics of the pulverized biomass flames are almost the same as those of the gas flames.
