one unit of briquette molder can produce in one pressing pieces of cylindrical briquettes with a hole. each briquette has an approximate diameter of cm with a thickness of cm. the inner whole is cm. In producing briquettes, a hole at the center of the fuel is believed by many to improve the combustion characteristics of the briquette 21.
briquettes can be produced with a density 1.2 gcm from loose biomass of bulk density 0.1 to 0.2 gcm these can be burnt clean and therefore are eco-friendly arid also those advantages that are associated with the use of biomass are present in the briquettes.
