Equilibrium moisture content of biomass briquettes

Equilibrium moisture content (EMC) of commercially available biomass briquettes at 40–85% relative humidity was compared with the EMC of cotton stalks and saw mill waste. No significance difference in EMC was noticed at relative humidity value up to 70%. At higher relative humidity, the EMC of briquettes was lower compared to cotton stalks and woody saw mill waste. This may be due to higher specific density of biomass briquettes. The study shows that storage of briquettes during period of high humidity will not create any problem.
