4 FAQs about Steam turbine generator inlet air temperature

How does turbine inlet temperature affect power output?

The increase in turbine inlet temperature means an increase in superheat at constant inlet steam pressure and condenser pressure gives a steady improvement in the power output of the turbine. Raising the inlet steam temperature also reduces the wetness of the steam in the later stages of the turbine and improves the power output of the turbine.

How does a steam turbine inlet air cooling scheme work?

The inlet air cooling scheme's transformation effect is calculated across varying temperatures, under the condition of ensuring the maximum air precooling capacity. Post-transformation, steam turbine inlet pressures rise, while exhaust temperatures of exhaust gas decrease.

What are the parameters of a steam turbine?

These parameters encompass the mass flow rates of exhaust gas and fuel, exhaust gas temperature, steam turbine back pressure and temperature, power generation of the gas turbine, steam turbine, and GSCC, as well as their respective thermal efficiencies under a series of ambient temperature and power generation load.

How does steam inlet temperature affect turbine performance?

Turbine steam inlet temperature is another major parameter affecting turbine performance. Reducing steam inlet temperature reduces the enthalpy, which is a function of both the inlet temperature and pressure. At higher steam inlet temperatures, heat extraction by the turbine will also be increased.
