Supply assembly for a turbine of a solar thermodynamic system and solar thermodynamic system comprising said assembly

Supply assembly for a turbine of a solar thermodynamic system of the type provided with a plurality of parabolic mirrors arranged for converting solar energy into thermal energy for heating a first thermal carrier fluid contained in a tank to a first temperature, comprising:

• a column structure provided at the upper part with an exit for bleeding saturated dry steam:
• a lower portion provided with two inlets connected to said tank such as to be supplied with said first thermal carrier fluid heated by said mirrors, said lower portion comprising a first heat exchanger and a second heat exchanger arranged for being supplied with a second thermal carrier fluid at an overheating temperature and re-overheating temperature, respectively;
• an upper portion fluidically connected to said lower portion and arranged above it so that said first thermal carrier fluid can pass from said lower portion to said upper portion, said upper portion comprising a boiler arranged for bringing said second fluid at a boiling temperature following the heat exchange with said first fluid, and a cylindrical body arranged on said boiler for generating steam for supplying said turbine;
• a preheating and supplying structure arranged for heating said second thermal carrier fluid up to a preheating temperature and supplying said upper portion of said column structure with it.
