In case temperature of the separated water is rather high (higher than 1000C) at the fields of steam-water mix, the additional steam can be obtained by expansion (pressure drop in expander). The obtained steam flows into intermediate turbine inlet. It allows getting the additional work and, hence, increasing the efficiency of power installation. Theoretically, there can be several similar cascades.
