Determination and Analysis of Far-infrared Emissivity from Bamboo Charcoal

Far-infrared emissivity of bamboo charcoal was determined under different carbonization temperature,preservation time and different aged bamboo.Inquiry was made into different factors influencing the emissivity.The results showed that bamboo charcoal had excellent far-infrared emissivity.Carbonization temperature had the greatest influence to emissivity of the charcoal,followed by age of bamboo and holding time.The best technology for bamboo charcoal with high far-infrared emissivity was as follows: carbonization temperature of 700℃,4-year culm and holding time of 5 hours.Produced charcoal had the highest emissivity of 0.937.
