COGEN HEAT LOAD MATCHING THROUGH REHEAT AND CAPACITY MATCH |
摘要 |
One example of a gas turbine engine may include a gas generator, a reheat combustor that is disposed downstream of the gas generator, and a power turbine that is disposed downstream of the reheat combustor and includes a plurality of nozzle guide vanes. The reheat combustor is configured to increase a fuel flow so as to increase a temperature of the reheat combustor and match a required exhaust temperature. The nozzle guide vanes are configured to increase a real capacity at a power turbine inlet in proportion with the required exhaust temperature. A constant apparent capacity at a gas generator exit upstream of the reheat combustor remains constant, in response to proportionately increasing the temperature and the real capacity with respect to one another. |

1. A gas turbine engine, comprising:
a gas generator; a reheat combustor downstream of the gas generator; and a power turbine downstream of the reheat combustor and having a plurality of nozzle guide vanes; wherein the reheat combustor is configured to increase a fuel flow so as to increase a temperature of the reheat combustor and match a required exhaust temperature; wherein the nozzle guide vanes are configured to increase a real capacity at a power turbine inlet in proportion with the required exhaust temperature; wherein a constant apparent capacity at a gas generator exit upstream of the reheat combustor remains constant, in response to proportionately increasing the temperature and the real capacity with respect to one another. |
