Vineyard residues as a fuel for domestic boilers in Trento Province (Italy): Comparison to wood chips and means of polluting emissions control

The results, to be considered as preliminary, show that vineyard residues had higher emissions compared to the remaining fuels, including organic vineyard residues, but always within the limits prescribed in Italy. In terms of total heavy metal emissions no significant differences could be detected among the tested fuels. The electrostatic filter proved to be effective in the reduction of total fly ash emissions as well as the use of pelletized biomass.
