Wood Briquettes (blocks of sawdust) that are ecologically clear solid fuel made from pure wood sawdust. Briquettes are made under high pressure, so they consists no binder material. Can be used for solid fuel burners, heating systems and etc. Here are results of test for wood briquettes: Moisture of operative fuel (Wd) - 4.6% Ash of absolutely dry mass (As) - 0.2% Amount of sulphur (S) - 0.*1% Heat value of absolutely dry mass (Q) - ****0 kJ/kg (***0 kkal/kg) Lower heat value of operative fuel (Q) - ****0 kJ/kg (***0 kkal/kg)
