Densification of Product Torrefaction from Coconut Coir to Bio-briquette as Renewable Energy that Environmentally

Abstract

Coconut coir waste which has a high calorific value can still be used as fuel by way of briquettes. bio briquette production is done by using torrefaction reactor and hydraulic press machine with different particle size and pressing pressure. Variations in particle size used were 60, 80 and 100 mesh and the pressure variations used were 100, 110 and 120 bar. The process used is torrefaction and densification. Characteristic analyzes of bio briquettes include compressive strength and heat value test. In this experiment, bio briquette produced with calorific value 21065.47 kJ/kg obtained at 60 mesh particle size with pressurization pressure of 120 bar and the highest compressive strength of 7,526 kg/cm2 was obtained at 100 mesh particle size with pressure of 120 bar.
