6 FAQs about [Air-cooled steam turbine generator cooling air chamber]

How does a gas turbine cooling system work?

The cooling system operates in series with the reheater, with gas turbine cooling steam returned to the steam cycle cold reheat line. Air extracted from the compressor discharge is cooled using water from the IP economizer. The cooled air is readmitted to the gas turbine and compressor to cool compressor wheels and

What is turbine inlet air cooling?

Turbine inlet air cooling is a group of technologies and techniques consisting of cooling down the intake air of the gas turbine. The direct consequence of cooling the turbine inlet air is power output augmentation. It may also improve the energy efficiency of the system.

Can Inlet air cooling improve gas turbine performance?

Inlet air cooling has been widely studied and established as means of improving the performance of gas turbine power plants (in both simple and combined cycle configurations) operating in arid and tropical weather conditions (Mohanty & Paloso, 1995).

How does a steam turbine condenser work?

Steam exiting the steam turbine unit is delivered directly to the air-cooled condenser (ACC) where it is condensed inside finned tubes, by air blown across the exterior finned surfaces with one or more fans arranged in cells. Fig. 2a. Typical schematic of a dry cooling (air-cooled) system.

How does a LP steam turbine cool a gas turbine?

In addition to providing start-up cooling steam supply to the gas turbine cooling steam circuit, the HP steam extraction after the first superheater pass is used to cool the LP steam turbine from ~70% speed until steam turbine loading is underway. Figure 2 includes a diagram of the three-pres-sure, reheat HRSG.

Do chillers increase gas turbine power output?

Jonsson and Yan (2005) concluded that using chillers for inlet air cooling can increase gas turbine power output by 15–20% and efficiency by 1–2% (i.e. if gas turbine exhaust gas thermal energy is recovered).
