(54) Apparatus for generating electric energy using high temperature fumes


(57) This invention concerns an apparatus for the production of electric energy by a turbine operating according to the Rankine cycle using an organic work fluid made to evaporate through a heat exchange with a source of heat. In the work fluid circuit, upstream of the main turbine, an additional electric generator is inserted having a rotation speed aimed at optimising the extraction of power from a pre-expansion of the work fluid.
