ABSTRACT 

The researchers conducted experiments to evaluate how the introduction of a modifier affected the heating efficiency and stability of the flame in sago waste briquettes. The adjuster was used to maintain a constant distance during burning, which improved the combustion heat of the fuel. Infrared thermometry was used to monitor the temperature changes within the briquette and the combustion load represented by water in a pan. The results show that adding an effective adjuster significantly enhances the performance of both the briquettes and the stove, leading to improved effectiveness and efficiency. This is evident from the higher combustion temperature and faster boiling time of the water. The consistent burning distance ensures a stable and even supply of heat to the briquettes, enabling more efficient utilization of the fuel as all parts of the fuel can fully burn and transfer heat to the pan. Molecular analysis indicates that the stability of the burning distance weakens the Van der Waals bonds within the carbon chain, resulting in increased reactivity of the fuel molecules. As a result, the fuel exhibits improved ability to absorb heat and becomes highly flammable.

Keywords: Heat, flame characteristics, sago waste, briquettes.
