Quality analyses of biomass briquettes produced using a jack-driven briquetting machine

Abstract

The study relates to a compact briquetting machine developed in the Philippines that can compress and produce cylindrical briquettes having a hole at the center using biomass and urban wastes with the aid of a hydraulic jack and is semi-automatically returned to start position using a pulling device. The machine can compact 16 cylindrical briquettes in one pressing or about 200 to 240 pcs/hr. The quality of the three types of briquettes produced using waste paper, sawdust and carbonized rice husk, slightly varied. Parameters analyzed like bulk density, heating value, moisture, N and S closely met or has met the requirements of DIN 51731.
