Figure 20. Potassium Content of the Sand Outer Layers.
Potassium content in different fuels tested and their ashes is given in Table 27. Based on
the analysis given in Thomas et al. (1995) percentage of K in ash is very high for vinasse and
raffinate as compared to other biomass fuels (from literature) such as wood, paper, begasse.
The potassium content of pressed pulp is lower than hull, shell and pits but is higher than
wood, begasse, paper etc. and is comparable with straw and grass. Thus, based on the analysis
pulp has a higher propensity of agglomeration than wood and paper but is lower than hull,
shell and pits. Moreover, due to their higher potassium content, agglomeration tendency of
vinasse and raffinate is very much higher than some of the other biomass fuels available.
