Definitions

  • the present invention relates to a closed circuit operating according to a Rankine cycle with a device for emergency shutdown of this circuit as well as to a method using a circuit with such a device.
  • the Rankine cycle is a thermodynamic cycle by which heat from an external heat source is transferred to a closed circuit which contains a working fluid. During the cycle, the working fluid undergoes phase changes (liquid/vapor).
  • This type of cycle generally breaks down into a step during which the working fluid used in liquid form is compressed isentropically, followed by a step where this compressed liquid fluid is heated and vaporized in contact with a heat source.
  • This vapor is then expanded, during another stage, in an expansion machine, then, in a final stage, this expanded vapor is cooled and condensed in contact with a cold source.
  • the circuit comprises at least one pump-compressor for circulating and compressing the fluid in liquid form, an evaporator which is swept by a hot fluid to carry out at least partial vaporization of the compressed fluid, an expansion machine to expand the steam, such as a turbine, which transforms the energy of this steam into another energy, such as mechanical or electrical energy, and a condenser by which the heat contained in the steam is given up to a cold source, generally outside air, or even a cooling water circuit, which sweeps this condenser, to transform this vapor into a fluid in liquid form.
  • a pump-compressor for circulating and compressing the fluid in liquid form

  • the presence of working fluid in the liquid state in at least part of this evaporator or further in the circuit leads to the production of steam during several tens of seconds after the activation of the emergency stop.

  • the expansion machine being thus short-circuited, the circuit is no longer able to produce energy and the production of energy quickly stops.
  • this second valve is located in a branch of the circuit where the working fluid is both under pressure, hot and in gaseous form. It must therefore be chosen accordingly with materials resistant to temperature and pressure and with a size, in particular at the level of its passage section, adapted to allow the flow of steam to pass in the event of its actuation.
