ABSTRACT:
Two of the primary baseline selection decisions to be made during the conceptual design of the 100 MWe Solar Central Receiver/Fossil Hybrid Power System are: (1) which fossil fuel to use to fire the sodium heater, and (2) what is the optimum solar multiple for the selected fuel. A diagram
The turndown ratio of the sodium heater (rated power/minimum operating power) is determined primarily by the fuel being fired. When the heater is at minimum power, the difference between the steam generator power and heater power is the required receiver power.
Once the fuel is known and the turndown specified, the economic effects of varying solar multiple can be determined and an optimum solar multiple selected. (For a parallel heater/receiver configuration, 1-1/turndown ratio is the point of departure for solar multiple selection trade studies.) Selection of the solar multiple in conjunction with the steam generator power determines the size of the receiver and receiver sodium components in terms of required power and indicates the size of the thermal storage subsystem.
The purpose of these trade studies is to select a fossil fuel and receiver size (power) for the 100 MWe conceptual design of the Solar Central Receiver Hybrid Power System. These parameters form the basis of other ongoing trade studies.

of the general configuration of the hybrid power system is shown in Figure A-1. The turndown ratio of the sodium heater (rated power/minimum operating power) is determined primarily by the fuel being fired. When the heater is at minimum power, the difference between the steam generator power and heater power is the required receiver power.
