## Abstract
Abstract Mixture of Low-Rank Coal (LRC) with Candlenuts Shell (CNS) has been carried-out to improve the quality of combustion. The quality of combustion is affected by combustion reactivity, thermal efficiency and combustion emission. This study investigated the effect of the mixture of CNS and LRC to find-out its combustion reactivity. An experimental study has been done to investigate the combustion reactivity of mixing LRC and CNS with the addition of CNS to LRC of 10%, 30%, 50%, 70% and 90% respectively. Testing methods including proximate and ultimate analysis following ASTM Standard and sample combustion in electric furnaces were applied with a combustion temperature of 500 °C, 625°C, 750 °C and 875°C respectively. Oxygen was used as an oxidizer in this experiment. The result of the experimental test shows that the addition of CNS into LRC generally increased its combustion reactivity. This fact indicates that adding CNS into LRC improves significantly the combustion quality of CNS and LRC mixture. The optimum addition of CNS into LRC to increase combustion reactivity is 10%.
