Methods and turbine inflating the organic working fluid in Rankine cycle

摘要

Method for inflating an organic working fluid in the A Rankine cycle includes a step for supplying working fluid to the turbine. Turbine, it is possible to have many columns in many rows and stator blades it is arranged alternately in the rotor blades that are constrained to a shaft which rotates with the rotation axis center, and constitutes the corresponding turbine stages. Advantageously, the method further includes the following steps. a) the step of causing the radial direction of the stage of the first expansion of one or more of the turbine working fluid. b) The working fluid exiting the radial direction of the stage, the step of changing the orientation and the tangential direction of the axis with respect to the rotation axis. c) a second fluid expansion, causing the one or axial stage beyond that of the turbine. Step b) corresponds to the enthalpy change of at least 50% in the same working fluid enthalpy change of the average offered to complete the expansion of the fluid in the turbine. In addition, a turbine for expanding the organic working fluid in the Rankine cycle can execute the method.
