Claim Text:
1. A concentrating solar power system comprising: a solar flux receiver to heat solid particles dropped therethrough using energy from concentrated solar flux incident on the solar flux receiver; and a fluidized-bed heat exchanger to receive solid particles heated by the solar flux receiver, fluidize the solid particles to form a gas-solid fluid, and transfer heat from the gas-solid fluid to a working fluid, wherein: the fluidized-bed heat exchanger includes a stackup hybrid boiler having a stationary bed super heater with a turbulent bed evaporator on top of the stationary bed super heater, and a fast bed preheater on top of the turbulent bed evaporator, and a gas-solid separator to separate the solid particles from gas in the gas-solid fluid after the gas-solid fluid has passed through the fast bed preheater.
