4 FAQs about Steam turbine generator cooling air inlet
What is a typical gas turbine power plant with inlet air cooling system?
Schematic diagram of a typical gas turbine power plant with inlet air cooling system is shown in Figure-1. It is comprised of a single shaft gas turbine generator, heat recovery steam generator, electric chillers, thermal storage, and heat exchanger for inlet air cooling. The gas turbine generates electricity from combustion of natural gas.
Do inlet air cooling methods improve turbine power output?
All inlet air cooling methods for gas turbines offer important improvements in turbine power output. Some key findings in this respect include: For evaporative cooling, Hosseini et al. (2007) analyzed a system installed in gas turbines of a combined cycle power plant in Fars (Iran).
What is inlet air cooling for gas turbines?
At a basic level, the main principle behind all inlet air cooling methods for gas turbines is to reduce air temperatures at the compression entry with the aim of improving the turbine's performance. Here, it's key to understand turbine performance is highly dependent on ambient conditions, including humidity and ambient temperatures.
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.
