The paper aims to contribute to a better understanding of the thermodynamic concept of heat regeneration in steam power plants with a finite number of bleedings. A regenerative Rankine cycle is compared to a complex system (CHC - complete hybrid cycle) composed by one non-regenerative Rankine cycle (HEC – hybrid engine cycle) and more reverse...

In this paper, the effect of fuel composition on gasification exergetic efficiency is investigated with the aid of equilibrium and non-equilibrium models. The work aims at comparing, for different fuels, the second principle theoretical efficiencies of air gasification and oxygen-steam gasification. The study considered several fuels, ranging...

The EBBSG (External Boiling Bayonet Steam Generator) system, proposed in previous publications, offers an alternative to the classical once-through high pressure steam generators. This system exploits the combination between the Loeffler external boiling scheme and the bayonet-tube steam generator and is expected to provide advantages in terms...

Heat recovery steam generators (HRSGs) are at present largely utilized in energy production power plants, especially in combined cycles that are characterized by high efficiency and flexible behaviour in the deregulated electricity market of today. Due to their critical importance, HRSGs operation is continuously controlled by the installation...

Negli ultimi anni la preoccupazione per la disponibilità di combustibili convenzionali e le regolamentazioni a difesa dell'ambiente hanno incentivato l'utilizzo delle fonti alternative a scopi energetici; tra queste, le biomasse stanno acquisendo una crescente importanza, in particolare per la Liguria, regione ad elevato indice di boscosità. Il...

Abstract The present paper aims to propose an original steam generation system, which resulted suitable for the application to the secondary loops of lead-cooled fast reactors: reaction heat is extracted from the lead by means of a coolant under vapor phase, thanks to both an external feed-water boiling and special bayonet tubes in the...

Failure analysis through simulation is a useful practice to predict a system availability, maintenance times and costs over even long time periods. So far, computational tools for failure analysis have been designed mainly for electronic components. This paper presents a software tool aimed at carrying out the failure analysis of complex plants...
