Title:

Comparison of yield and quality of bamboo charcoal produced by external heating employing metal drum retort

Authors:Dhamodaran, T.K

Abstract:: External heating method was evaluated for the production of charcoal from Bambusa bambos employing metal drum retort having facility for recovering the pyrolignious vapour for burning purpose. Bamboo charcoal with low volatile (11.8%) and high fixed carbon (81.6%) was obtained. When the design of the retort was improved for recovering the distillate by condensation, charcoal with still higher quality (volatile content 9.0%, fixed carbon 84.2%) was achieved. Charcoal yield, on oven dry basis ranged from 31 to 33 per cent. The product was alkaline with a mean pH of 9.7 and mean iodine value of 256. The ash content of bamboo charcoal produced was found 6.7 per cent

Keywords:bamboo charcoal; charcoal retort; charcoal yield; charcoal properties.
