Embodiment Construction

[0014] In the following specification and claims, various terms will be referred to, and these terms shall be defined to have the following meanings.

[0015] The singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise.

[0016] Unless otherwise indicated, approximate language such as "substantially," "substantially," and "about" as used herein indicates that such modified terms may apply only to an approximate degree, as one of ordinary skill in the art will recognize, rather than absolute or perfect degrees. Accordingly, a value modified by a term or terms, such as "about," "approximately," and "substantially," is not to be limited to the precise value specified. In at least some cases, the approximate language may correspond to the precision of the instrument used to measure the value. Here, as well as throughout the specification and claims, limitations of scope may be identified. Unless context or language dictates othe...

Abstract

The invention relates to a system and a method for operating a turbocharged gas turbine engine. A power generation system (100) includes a combustion system (102), a turbocharger (106), and a heat recovery system (104). The combustion system (102) is configured to burn a fuel with the airflow. The combustion system (102) is further configured to generate an exhaust stream. The turbocharger (106) is configured to compress the flow of compressed air and direct the flow of compressed air to the combustion system (102). The combustion system (102) is configured to burn a fuel with a compressed airflow and an additional airflow. The heat recovery system (104) is configured to recover heat from the exhaust stream and drive the turbocharger (106). The heat recovery system (104) uses a supercritical working fluid to absorb heat from the exhaust stream and drive the turbocharger (106).

Description

Background technique [0001] The field of the present disclosure relates generally to gas turbine engines, and more particularly, to systems and methods for operating turbocharged gas turbine engines. [0002] A gas turbine engine typically includes at least one compressor, at least one burner, and at least one turbine arranged in a serial flow configuration. Typically, a compressor directs compressed air to a burner where it is mixed with a fuel flow and combusted to form a high temperature combustion gas flow that is directed toward the turbine before being discharged from the gas turbine engine. However, in areas of high altitude or high ambient temperature where the air has a lower density than at low altitude or low ambient temperature, less air is compressed and less fuel is burned due to the lower density air , the gas turbine engine produces less power. [0003] To overcome the shortages at higher altitudes and high ambient temperature regions, at least some known gas...
