SINGLE INTERMEDIATE PRESSURE OPERATION MODE FOR SOLAR DRIVEN STEAM TURBINE PLANTS

摘要

The present invention discloses a steam turbine plant using steam generated by a solar field, which comprises a high pressure turbine (1) with an inlet for inputting the steam and an outlet for outputting the steam, a mid or low pressure turbine (3) with an inlet for inputting the steam outputted by the outlet of the high pressure turbine (1) and an outlet for outputting the steam into a condenser (5), a reheater (7) arranged between the high pressure turbine (1) outlet and the mid or low pressure turbine (3) inlet and which is arranged for reheating steam outputted by the high pressure turbine (1) outlet, wherein the high pressure turbine (1) outlet is connected with the condenser (5) via a pipe (9), and wherein a first flow control device (11) which controls the flow of the steam in the pipe (9) and a temperature control device (13) which cools the steam in the pipe (9) are arranged downstream of the high pressure turbine (1) outlet and upstream of the condenser (5).
