FACTORS INFLUENCING ICP, SCP AND ENERGY EFFICIENCY OF FUEL BRIQUETTES FROM WOOD PROCESSING WASTE FROM MORAMANGA DISTRICT, ALAOTRA MANGORO REGION

ENERGY AND ENVIRONMENT

The Moramanga district has long been known for its wealth of forest resources on the one hand and the existence of the state-owned company FANALAMANGA and several free zone enterprises working in the field of forest exploitation and export on the other. These companies generate a lot of wood processing waste every day: planing shavings, sawdust ... etc. which are left in the open air through the open spaces in the district's chief town. The purpose of this work is on the one hand to valorise these forest wastes for energy purposes by producing combustible briquettes based on planing shavings and sawdust and on the other hand to determine the Lower Calorific Value (LCV) and the Higher Calorific Value (HCV) of these combustible briquettes. The aim of this work is therefore to have an alternative fuel capable of substituting wood energy. Two important parameters were studied: the binder and the fine materials, varying their respective contents. The result of this research work showed that there is a correlation between the binder content and that of the fine materials used. The briquette based on planing chips with 5% binder is the most efficient as it has a high Lower Calorific Value (LCV: 6897.66 kcal/kg, a power of 745.7 W, an efficiency of 39.5% compared to wood energy and other fuel briquettes produced and studied.
