Abstract
A system may include a gas turbine system. The gas turbine system may include a compressor, such that the gas turbine system may produce exhaust gas in an exhaust outlet when generating electricity. The system may also include a heat recovery steam generator (HRSG) that may use the exhaust gas to create steam, a manifold system configured to couple compressed air in the compressor to the exhaust outlet, and a controller configured to send a command to the manifold system to couple the compressed air to the exhaust outlet when a temperature of the exhaust gas is above a threshold.
Claims20
A system comprising:
- a gas turbine system comprising a compressor, wherein the gas turbine system is configured to produce exhaust gas in an exhaust outlet when generating electricity;
- a heat recovery steam generator (HRSG) configured to use the exhaust gas to create steam;
- a manifold system configured to couple compressed air in the compressor to the exhaust outlet;
- and
- a controller configured to send a command to the manifold system to couple the compressed air to the exhaust outlet when a temperature of the exhaust gas is above a threshold.
A non-transitory machine readable medium, comprising computer-executable instructions configured to cause a processor to:
- monitor a temperature of exhaust gas provided to a heat recovery steam generator (HSRG) via an exhaust outlet;
- and
- send a command to a manifold system when the temperature exceeds a threshold, wherein the command is configured to cause the manifold system to couple compressed air to the exhaust outlet.
A manifold system, comprising:
- one or more valves configured to couple compressed air from a compressor of a gas-turbine system to an exhaust outlet of the gas-turbine system, wherein the exhaust outlet is configured to provide exhaust gas to a heat recovery steam generator (HSRG);
- and
- a control system configured to adjust the one or more valves to couple the compressed air to the exhaust outlet when a temperature of the exhaust gas is above a threshold.
