Hot Air Ignition Characteristics of Cotton and Corn Straw Pellet Based on TG-DTG

Abstract:

In this paper, using TG-DTG and single pellets hot air ignition experiment to study the hot air ignition characteristics of biomass forming granule, analyzes the hot air temperature, velocity, flow rate of its influence on ignition performance. It was found that the weight loss rate of surface material significantly higher than the center materials of the pellet at different heating rates through the experiment, and lignin pyrolysis accelerated leading to substantially coincide of hemicellulose, cellulose and lignin pyrolysis, With the increase of air temperature, maximum weight loss rate increased, the pellet heating rate accelerated, sped up the pellet ignition, the ignition temperature should be above 500°C. As the increase of gas flow, the weight loss of corn stalks is reduced after increased first, little change in the final weight loss. Weight loss rate is decreased first and then increased. The maximum weight loss rate is essentially the same at low flow, but the maximum weight loss rate reduced and the time extension after more than 50ml/min.
