System and method for thermal control in a gas turbine engine

摘要

A system includes a gas turbine engine that includes a compressor section configured to generate compressed air and a combustor coupled to the compressor section. The combustor is configured to combust a first mixture comprising the compressed air and a first fuel to generate a first combustion gas. The gas turbine engine also includes a turbine section coupled to the combustor. The turbine section is configured to expand the first combustion gas to generate an exhaust gas. The gas turbine engine also includes a boiler coupled to the turbine section. The boiler is configured to combust a second mixture comprising a portion of the first combustion gas and a second fuel to generate a second combustion gas that is routed to the turbine section. In addition, the boiler generates a first steam from heat exchange with the second combustion gas.

1. A system, comprising:
a gas turbine engine, comprising:
a compressor section configured to generate compressed air;a combustor coupled to the compressor section, wherein the combustor is configured to combust a first mixture comprising the compressed air and a first fuel to generate a first combustion gas;a turbine section coupled to the combustor, wherein the turbine section is configured to expand the first combustion gas to generate an exhaust gas; anda boiler coupled to the turbine section, wherein the boiler is configured to combust a second mixture comprising a portion of the first combustion gas and a second fuel to generate a second combustion gas that is routed into the turbine section at a gas return location downstream from the combustor, and wherein the boiler generates a first steam from heat exchange with the second combustion gas.
