Abstract
The aim of this research is to scrutinize the effect of blend solid fuels consisting of coalite, coconut shell charcoal and gelam wood charcoal on calorific value. Coalite is the solid fuels made from coal that is mined from the earth, while coconuts shell charcoal and gelam wood charcoal are processed from natural plants. Coalite, coconut shell charcoal and gelam wood charcoal are solid fuels which was obtained from carbonization process or pyrolitic process of fuel material. Gelam wood charcoal has larger volatile matter and fixed carbon compared to coalite and coconut shell charcoal. These cause an increase in calorific value. A significant increase in calorific value obtained when coalite and coconut shell charcoal blended with a ratio of 75:25, with an increase of 8.38%. With an equal blending ratio coalite and coconut shell charcoal and coconut shell charcoal with gelam wood charcoal can increase the calorific value up to 3.80% and 3.18% respectively.
