Valorization of Bio-Briquette Fuel by Using Spent Coffee Ground as an External Additive

Popis výsledku v původním jazyce

The present study investigates the quality changes of wood biobriquette fuel after the addition of spent coffee ground (SCG) into the initial feedstock materials (sawdust, shavings) in different mass ratios (1:1, 1:3). Analysis of SCGs fuel parameter proved great potential for energy generation by a process of direct combustion. Namely, level of calorific value (GCV = 21,58 MJ/kg), of ash content (Ac = 1,49%) and elementary composition (C = 55,49%, H = 7,07%, N = 2,38%, O = 33,41%) supports such statement. A comparison with results of initial feedstock materials exhibited better results of SCG in case of its calorific value and elementary composition. Bulk density (kg/m3) and mechanical durability (%) of biobriquette samples from initial feedstock materials were following for sawdust: bulk density was 1026,39 kg/m3, mechanical durability was 98,44% and shavings: bulk density was 1036,53 kg/m3, mechanical durability was 96,70%. The level of such mechanical quality indicators changed after the addition
