Abstract

TG（thermogravimetry）-DTG（differential thermogravimetry）-DSC（differential scanning calorimetry）thermal analysis technology was used to analyze the combustion performance of charcoal briquettes made from a control of pine and fir sawdust and epicarps of hickory （Carya cathayensis），chestnut （Castanea mollissima），and Camellia oleifera. Results showed that the combustion-alleviative phase temperature of the charcoal briquettes made from epicarps was 435.4 ℃ for hickory，448.1 ℃ for chestnut，and 412.3 ℃ for C. oleifera，compared to the control of 519.8 ℃. The peak value for the combustion rate curve and exothermic curve showed：control charcoal＞C. oleifera-epicarp charcoal and chestnut-epicarp charcoal＞hickory?-epicarp charcoal. Comparing five parameters：ignition temperature，maximal heat-release，maximal combustion rate，maximum weight loss rate，and temperature of the maximum weight loss rate，revealed that control charcoal＞chestnut-epicarp charcoal＞C. oleifera-epicarp charcoal＞hickory-epicarp charcoal. The control charcoal had an ignition temperature of 504.4 ℃；whereas the hickory-epicarp charcoal was 408.6 ℃. The maximal heat-release for the three kinds of epicarps was 87.76（hickory），92.07（chestnut），and 84.82 Wg－1（C. oleifera）with the control charcoal briquettes having 95.12 Wg－1. Thus， the charcoal briquettes which have different ignition temperature and combustion character could be made by different addition amount of the three kinds of epicarps.［Ch，4 fig. 2 tab. 12 ref.］
