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.
EnglishIt is nowadays well known that ORC systems can represent a very interesting way to recover thermal power discharged by other power generating units when the use of thermal power as such is not possible. Many examples can be found in Italy and other countries where the existence of incentives for electrical power generation by stationary ICEs fed using biomasses (such as biogas, vegetable oils and others) makes the operation of these systems feasible even if the heat is totally wasted. As shown in previous works by the authors and in other works available in the open literature ORCs can recover a significant amount of the thermal power available from a stationary engine converting it into electrical power with the effect of increasing the overall generating efficiency. A good matching of these two systems and the correct design of components such as evaporator and turbine for the ORC are however requested. Also a proper selection of the fluid to be employed within the ORC is crucial to enhance the overall benefits. After briefly describing the models of ICE and ORC, the full ICE-ORC combined plant layout is created in the Simulink® environment and used to run simulations under transient operating conditions as well as ICE off design conditions, showing the flexibility and usability of the realized simulation tool for design purposes.

| Abstract: | It is nowadays well known that ORC systems can represent a very interesting way to recover thermal power discharged by other power generating units when the use of thermal power as such is not possible. Many examples can be found in Italy and other countries where the existence of incentives for electrical power generation by stationary ICEs fed using biomasses (such as biogas, vegetable oils and others) makes the operation of these systems feasible even if the heat is totally wasted. As shown in previous works by the authors and in other works available in the open literature ORCs can recover a significant amount of the thermal power available from a stationary engine converting it into electrical power with the effect of increasing the overall generating efficiency. A good matching of these two systems and the correct design of components such as evaporator and turbine for the ORC are however requested. Also a proper selection of the fluid to be employed within the ORC is crucial to enhance the overall benefits. After briefly describing the models of ICE and ORC, the full ICE-ORC combined plant layout is created in the Simulink® environment and used to run simulations under transient operating conditions as well as ICE off design conditions, showing the flexibility and usability of the realized simulation tool for design purposes. |
