Claim 19:
20. A system to generate electrical power, the system comprising:
a heat exchanger valve positioned to divert flow of compressed gas;
a heat exchanger gas inlet temperature sensor positioned to provide a gas inlet temperature, the gas inlet temperature defined by a temperature of the flow of compressed gas;
an external heat exchanger positioned to have a first fluid path to accept the flow of compressed gas via the heat exchanger valve and output the flow of compressed gas and a second fluid path to output a flow of an intermediate working fluid, the external heat exchanger also positioned to transfer heat indirectly from the flow of compressed gas to the flow of the intermediate working fluid;
a heat exchanger gas outlet temperature sensor positioned to provide a gas outlet temperature, the gas outlet temperature defined by a temperature of compressed gas;
a heat exchanger working fluid outlet temperature sensor positioned to provide an intermediate working fluid outlet temperature, the intermediate working fluid outlet temperature defined by a temperature of intermediate working fluid;
a gas bypass valve positioned to divert flow of the compressed gas from the external heat exchanger based on associated gas inlet temperature and gas outlet temperature;
a working fluid flow control device positioned to control the flow of the intermediate working fluid to the external heat exchanger; and
a power generation unit to indirectly transfer heat from an intermediate working fluid to a main working fluid, thereby to cause the main working fluid to change phases from a liquid to a vapor, the flow of the vapor positioned to generate electrical power and to cause the main working fluid to change phases from the vapor to the liquid.
