Beschreibung
Zusammenfassung:	A standby heat supply system is provided for a solar receiver steam generator to maintain the system at a relatively constant temperature during the nocturnal period when solar radiation is unavailable. An exemplary solar steam generator having a standby heat supply system includes a steam loop having at least one solar panel, a steam drum and circulating pump, whereby solar energy heats the water to generate steam which is provided to the steam drum. The standby heat supply system includes an external standby heater wherein the water from the steam drum is provided to the external standby heater. A heat isolation valve is actuated during the nocturnal period to allow the water to circulate through the standby heater. Another exemplary embodiment of a solar steam generator includes an internal standby heat supply system having heater elements immersed in the steam drum for direct heating of the water during nocturnal periods.
