    Abstract

    This experiment was done to find the optimum quali t y of Kalimantan wood briquette f rom merbau t ypes and the combusti on kinet i cs f rom the optimum briquette. The parameter of physical properties was ini t ial and relaxed densi t y, durabili t y, axial compressive strength, and water resistance. Whereas the objective of the combust i on kinet i cs is to find the act ivat i on energy and the pre-exponent i al factor of the optimum bri quette. The variati on of this experiment was briquetting pressure. It was 200 kg/cm 2 , 400 kg/cm 2 , 600 kg/cm 2 , 800 kg/cm 2 , dan 1000 kg/cm 2 , and wi th and wi t hout mollases as the binder. The reactor chamber temperature of combust i on kinet i cs test was 400 °C. From the experiment can be found that the optimum bri quetting pressure was 800 kg/cm 2 for wi t hout binder and 600 kg/cm 2 for wi th binder. The durabili t y value of bi omass briquette wi thout binder was poor, whereas using mollases as binder reduced the axial compressive strength of bi omass bri quette wi th moi ture content 15 %w.b. The water resistance of bri quette at thi s experiment also poor. At 2 m/s and 0,05 m/s combusti on air rate, the activat i on energy of bri quetting pressure 800 kg/cm 2 were 20.52 kJ/mol and 31.16 kJ/mol , nevertheless the act ivat i on energy of briquetting pressure at 600 kg/cm 2 wi th binder were 14.78 kJ/mol and 18.06 kJ/mol .
