Περίληψη

An innovative combustion unit was designed and implemented, aiming at the production of thermal energy, using different types of biomass fuels. The unit was made out of conventional materials, had a nominal capacity of 65 kWth and comprised a silo, a continuous feedstock supply system, a desiccator, a cutting mill, and a cross flow boiler. Among the two residues tested, olive kernels produced a higher thermal efficiency and lower CO, SO2, and NOx emissions. A series of experiments, conducted at different biomass/air feed rates, showed that at a feedstock mass flow of 14.4 kg/h improved combustion conditions and heat recovery were obtained. Gaseous emissions were kept below the threshold limits and system efficiency was 81.3%. The unit needs to be optimized in terms of air supply and optimal parameters control systems.
