Abstract:
This work presents innovative cogenerative Organic Rankine Cycles operating with fluids at high temperature (up to 400°C) coupled with a biomass-fired molten salts boiler, that allow to obtain an electrical efficiency over the threshold of 20%. Two fluids have been considered in this study, namely PP9 and TiCl4. The power plants are modeled with Aspen Plus. Both subcritical and supercritical cycles have been investigated. The cycle efficiencies obtained with PP9 is almost of 22%, while with TiCl4 is over 23%.
