Herbaceous energy crops are generally characterized by a higher ash content with a low melting point, and can contain high levels of nitrogen and sulphur, if compared to the wooden biomass. A series of combustion tests were carried out using a 15 kW commercial scale boiler in order to evaluate the possible application of pellets made using different energy crops (fiber sorghum, miscanthus and giant reed). The combustion performance, the tendency to the slag formation...
