Coconut fiber (CF) and eucalyptus leaves (EL) were upgraded by hydrothermal carbonization (HTC) and fuel qualities of corresponding hydrochars were determined in the present study. Compared to raw biomass, the hydrochars have increased energy density, and the decreased nitrogen and sulfur contents showed that reduced pollutant emissions are produced during hydrochar combustion. The ignition temperatures of hydrochars were higher and the combustion also shifted to higher temperature ranges. In addition, HTC significantly reduced the slagging and fouling tendencies of raw biomass and the fouling index of CF and EL changed from 2.59 to 0.09 and 1.11 to 0.24, respectively. This study demonstrated that solid fuel with high quality can be produced by HTC and improved thermal efficiency and environmental benefits can be achieved by hydrochar combustion.
