Abstract
Two analyzers were developed to evaluate the burning characteristics of charcoal. The burning rate analyzer measures the mass reduction rate of charcoals burning in a constant atmosphere; and the burning gas temperature analyzer measures the temperature change of burning charcoals in a constant atmosphere. In this study, the burning characteristics of beer lees charcoal, produced by successively drying, pressing under heating and carbonizing beer lees in a low oxygen atmosphere, were compared with those of two commercially available charcoals, Bincho-tan and Oga-tan, by using the two newly developed analyzers. The burning rate of Bincho-tan was found to be the slowest, while those of the beer lees charcoal and Oga-tan were similar to each other. The results showed the potential of the developed apparatuses for use in evaluating charcoal characteristics.
