EVALUATION OF CALORIFIC VALUE OF BIO-BRIQUETTE

Abstract

In developing countries more wastage is obtaining such as solid municipal wastage, agricultural wastages etc., and the problem of dumping arises. The effective utilization of that waste can solve that problem and also we generate power from those wastes. Hence the concept of bio-briquettes was introduced. Various technologies were used to made the briquettes such as screw extrusion, ramming, hydraulic pressing etc., At present briquettes are preparing from saw dust, rice husk, oil mill sludge etc., My paper presents the briquettes made from the palm tree branches mixed with coconut coir, saw dust, screw pine, Indian Bdellium tree powder in different proportions. The briquettes prepared in the different ratios of 100:0 with and without binder(P W100 ,P WO100), 100:50(P W50), 100:20 with and without binder(P W20 ,P WO20), 0:100 by using only additives(A W100). The proximate analysis was conducted and those are compared with the Indian coal. The moisture content is high for A W100 (8.53%),ash content is for A W100 (12.2%),volatile content is forP WB100 (86.9%),fixed carbon is for P W20 (17.38%) and calorific value KJ/KG is for P WO100 (19,351).
