Abstract
A system may include a turbine and a recuperative heat exchanger system. The recuperative heat exchanger system is configured to receive exhaust gases from the turbine. The recuperative heat exchanger system may include a precool section to cool the exhaust gases, a major heating section to receive the cooled the exhaust gases, and a minor heating section to receive the cooled the exhaust gases.
Claims20
A recuperative heat exchanger system, comprising:
- a first rigid framework;
- a precool section within the first rigid framework, wherein the precool section includes one or more heat exchangers configured to receive and cool an exhaust gas and output a cooled exhaust gas flow;
- a second rigid framework;
- a minor section within the second rigid framework, wherein the minor section includes a first minor heat exchanger and a second minor heat exchanger;
- a third rigid framework;
- a first major section within the third rigid framework, wherein the first major section includes a first major heat exchanger, a second major heat exchanger, and a third major heat exchanger;
- and
- a manifold configured to split the cooled exhaust gas flow from the precool section between a minor stream and a major stream, wherein the minor stream is provided to the minor section and the major stream is provided to the first major section.

A method, comprising:
- cooling an exhaust gas with a precool section within a first rigid framework, including outputting a cooled exhaust gas flow from the precool section;
- splitting the cooled exhaust gas flow with a manifold positioned outside of the first rigid framework into a major stream and a minor stream, including providing the major stream to a first major section within a second rigid framework and providing the minor stream to a minor section within a third rigid framework;
- flowing the minor stream through a first minor heat exchanger of the minor section and through a second minor heat exchanger of the minor section via one or more first curved flow loops;
- flowing the major stream through a first major heat exchanger of the first major section, through a second major heat exchanger of the first major section, and then through a third major heat exchanger of the first major section via one or more second curved flow loops;
- and
- flowing an effluent from the second minor heat exchanger of the minor section and the third major heat exchanger of the first major section to an exhaust gas manifold via secondary curved flow loops.
