Abstract:
Some constituents found in agricultural crop residues, especially their inorganic matter (ash), are linked to sintering, agglomeration, deposition, corrosion and erosion, which minimise both thermal efficiency and lifetime of the conversion equipment. In addition, emissions of particles generated during combustion of these solid biofuels could imply important health issues. These aspects are hindering the penetration of this type of resources in the energy market. One of the ways to reduce the problems associated to combustion of herbaceous biomass is to blend it with woody resources. On the other hand, the occurrence of sintering, deposition and corrosion phenomena can be tried to be foreseen by using predictive indices which values are obtained from the chemical composition of the fuel ashes or from their temperatures of deformation and fusion. However, these indices have certain limitations. Most of the authors who applied them to biomass agreed that it is necessary to carry out tests to adjust them to the real behaviour of the new fuels. In this paper, the values obtained for selected predictive indices for four different agropellets will be compared with the data collected in experimental tests carried out in a fixed-bed reactor with the same fuels. It will be studied the indices ability to predict the tendency to deposition and sintering detected in the tests.
