Using superheated hot air heat involves passing heat from hot air to sand in heat exchanger, passing heat from sand to compressed air, and feeding compressed air to turbine combustion chamber

摘要

The method involves passing the heat from the hot air to granular sand in a hot air-sand heat exchanger (16), passing the heat from the sand to compressed air at a temperature of at least 20 bar and feeding the heated compressed air to the combustion chamber (38) of a turbine (39). A solar tower power system (10,11) passes the hot air to the heat exchanger. AN Independent claim is also included for the following: a solar tower power system.
