Claim 26:
27. A system to generate electrical power, the system comprising:
one or more heat exchanger valves, each one of the one or more heat exchanger valves positioned on an associated supply pipeline;
one or more heat exchanger inlet temperature sensors, each of the one or more heat exchanger inlet temperature sensors to provide a gas inlet temperature;
one or more external heat exchangers, each of the one or more external heat exchangers connected to one of the one or more heat exchanger valves and at least one of the one or more heat exchanger inlet temperature sensors, each of the one or more external heat exchangers including a first fluid path to accept the flow of compressed gas via one of the one or more heat exchanger valves and output the flow of compressed gas and a second fluid path to accept and output a flow of an intermediate working fluid;
one or more heat exchanger outlet temperature sensors associated with one of the one or more external heat exchangers and to provide a gas outlet temperature, the gas outlet temperature defined by a temperature of compressed gas;
one or more gas bypass valves positioned to divert a portion of flow of the compressed gas from one of the one or more external heat exchangers based on associated gas inlet temperature, gas outlet temperature, and a gas temperature range; and
a power generation unit including a generator, an internal heat exchanger, and a loop for the flow of main working fluid, and a first fluid path of the internal heat exchanger, the internal heat exchanger including a second fluid path to connect to the one or more heat exchangers and the intermediate working fluid flowing therethrough, the internal heat exchanger positioned to transfer heat indirectly from the intermediate working fluid to the main working fluid so as to cause the main working fluid to change phases, thereby to cause the generator to generate electrical power.
