Effects of cellulose, hemicellulose, and lignin on the combustion behaviours of biomass under various oxygen concentrations

The combustion behaviours of three components, namely hemicellulose, cellulose, and lignin, and four types of biomass, namely rice straw, bamboo, peanut shell, and chestnut shell, were examined in a drop tube furnace set at 1273 K, in O₂/N₂ atmospheres containing 21-100% O₂. Radiant energy analysis technology was employed to infer the temperatures of the samples. The results show that the ignition mechanisms of cellulose and hemicellulose …
