CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
Englishis moving the attention towards the development of new combustion technologies. In the last two years several experimental tests were carried with the CRIBE pilot scale gasification facility. Although practical tests are utmost importance to highlights the process performance and reliability, there is a remarkable interest in a deeper knowledge of the gasifier behaviour. To this purpose a distributed model of the gasifier was developed. The model is meant to be used as interpretative tool which may help the analysis of the experimental tests. The model takes into account the sub-processes and heat fluxes involved in the gasification system. Specific tests with vine prunings were used to validate the model, which proved capable to reproduce the gasifier temperature profile.
