6 FAQs about [Secondary air temperature affects power generation]

Can a gas turbine inlet air cooling system increase power generation capacity?

Mohanty et al. investigated the integration of a gas turbine inlet air cooling system for a 100 MW gas turbine in Bangkok. They showed that reducing the intake air temperature from ambient condition to 15 °C can raise the gas turbine power generation capacity by 8%–13%.

How does temperature affect gas turbine output?

The output power and efficiency of gas turbines are profoundly influenced by ambient temperatures, with higher temperatures resulting in a notable decline in power output. This issue becomes particularly critical during periods of heightened power demand in hot climates.

Can reducing air temperature increase gas turbine power generation capacity?

They showed that reducing the intake air temperature from ambient condition to 15 °C can raise the gas turbine power generation capacity by 8%–13%. Consequently, the plant’s energy output can increase by 11%.

Does ambient air temperature affect gas turbine efficiency?

Their study showed that for every 1 °C rise in ambient temperature above ISO conditions, the gas turbine thermal efficiency decreases by 0.1%, and 1.47 MW of its gross (useful) power output will be lost. Bies et al. demonstrated that gas turbine output and efficiency are a strong function of the ambient air temperature.

Why do gas turbine engines need a secondary air system?

Consequently, there is a high demand for cooling and sealing to assure safe and sound operation throughout the operational envelope of an engine. Secondary Air Systems (SAS) play a significant role in gas turbine engines to accomplish reliable operation of the individual modules as well as the whole engine.

What are secondary airflow branches in a gas turbine engine?

Different flow elements, which have been developed as independent modules, can be used to build typical secondary airflow branches in a gas turbine engine, such as the turbine blade cooling air, the oil sump pressurization air, the disc cavity ventilation air, the axial bearing load control, etc.
