Woody biomass is a renewable source offering high potential for production of bio-fuels, -chemicals and -energy. During the outdoor storage of biomass biodegradation processes take place, which leads to mass reduction up to 30 wt%. To avoid these mass losses, the biomass was mixed with Ca(OH)2 in different ratios. To ensure, that this additive does not negatively influence further thermo-chemical conversion of biomass (e.g. by fluidized bed combustion), the spruce and poplar ash with and without additive was tested using ash melting microscopy. It was demonstrated that all the characteristic temperatures (DT, HT, FT) were significantly higher than the thermo-chemical conversion process temperatures in a fluidized bed. Thus it could be pointed out that the addition of Ca(OH)2 does not negatively influence ash melting behaviour, ash melting temperature respectively. |
