Abstract:
This work deals with the gasification of vine prunings, a common agricultural residue in Italy. The testing facility is a 200 kWt downdraft gasifier operating with air as a gasifying agent. Pressure drop, syngas flow¬rates, gas compositions and syngas outlet temperatures were monitored throughout the tests. Gas compositions were evaluated integrating a microGC and a FTIR analyzer. The first one allows evaluating all the gas species including hydrogen, nitrogen and oxygen but cannot provide a continuous measure of the gas compositions. Conversely the FTIR analyzer cannot detect homonuclear diatomic molecules but allows for a continuous detection of the syngas composition evolution. By this is way it was possible to provide both global performance parameters based on the average GC compositions and observations related to the gasifier dynamics. The gasification of vine prunings posed some operational issues. First the prunings had to be sieved in order to reduce the amount of dust which is harmful for the gasifier operation. Moreover vine prunings are a loose material; therefore the parameters of the feeding system had to be properly set in order to ensure the gasifier operation. The gasification of vine prunings led to quite satisfactory results in terms of gas composition and relatively low pressure drops. Therefore from an operational point of view the gasification of vine prunings is feasible after solving some issues.
