Two physical properties of briquettes, water resistance index and compressive strength were analyzed. The influence of type and quantity of biomass on physical properties was also studied. The results reveal that depending on the mineral content of the coal, the physical properties of the briquettes differ noticeably. The comparison of briquettes with and without biomass showed that the presence of the beet pulp increased CS in all types of coal samples. Samples containing beet pulp had better physical properties than sawdust. Mezino II coal briquettes had highest CS and WRI than the other ones. Calorific value of biomass/Mezino lI coal briquettes was lessened in comparison with raw coal, but it remained in an acceptable range.展开更多
