Burning Characteristic of Biocharcoal Briquettes Blend of Goat Manure Charcoal, Saboak Shell and Corn Cob

Abstract

This study aims to determine the effect of a mixture of goat manure charcoal, saboak shell and corn cob on the combustion properties of biocharcoal briquettes. The method used in this study was a completely randomised design consisting of 4 treatments and 4 replications. The treatment consisted of P1: 25% goat manure charcoal + 75% saboak shell without corn cob, P2: 25% goat manure charcoal + 50% saboak shell + 25% corn cob, P3: 25% goat manure charcoal + 25% saboak shell + 50% corn cob, P4: 25% goat manure charcoal + 75% corn cob without saboak shell. The results of variance analysis showed that the treatments had a significant effect (P<0.05) on the combustion temperature, combustion resistance and the ability to boil water, but a very significant effect (P<0.01) on the combustion rate, and no significant effect (P>0.05) on the colour and smoke. The mean values obtained are: combustion temperature 333.3°C; combustion rate 2.308 g/min; combustion resistance 195 min; colour 3.5 smoke 3.96 and ability to boil water 12.94 min. It is concluded that increasing corn cob charcoal with different proportions results in increased briquette temperature, combustion rate and combustion resistance tend to decrease, colour and smoke burning tend to be the same and the ability to boil water quickly.
