2.4 Determination of steam generation
The determination of steam generated during nights or cloudy periods
follows the energy balance of the superheater and evaporator. As first
solar beam appears the plant works as ISCC and the amount of steam
generated is the double Since ISCCS plants consists of two HRSG. To
recover some heat from the solar filed a solar steam generator HSSG is
used, made up of one heat exchanger: evaporator section. Referring to
Rankine-Hirn cycle (Fig. 3), the steam mass flow generated during the
day is evaluated as follows:
