Potential of poor lignite and Biomass blends in energy production

The present study investigated the potential of using poor lignites from different seams in N. and S. Greece and biomass blends in energy production. The experiments were conducted in a thermogravimetric analysis system, over the temperature range 25-850 degrees C. The efficiency of the process was evaluated in terms of combustion rate, burnout temperature, and time, as well as ignition and combustion indices. The thermochemical reactivity of lignites from N. Greece increased when biomass materials were added, while the fuels showed more or less an additive behavior upon blending. However, for lignites from S. Greece, co-combustion with biomass fuels showed synergy between component fuels.
