Air is used as the working fluid in a gas turbine power plant. The air compressor is used to compress air and is led to the combustion furnace where heat is added to the air, thus raising its temperature. In the compressed air, heat also added by burning fuel in the chamber or by the use of air heaters. The high-pressure air from the

4.1. Introduction: role of the compressor. Huge volume flows at high pressure are required to support suitable power generation in gas turbines. Delivering high pressurised volume flows is achieved by a compressor: a radial compressor is used for smaller volume flows, while an axial compressor is used for higher volume flows.
This is achieved in large aircraft gas turbines by "spooled" shafts where the shaft for the low-pressure end, driven by the low-pressure portion of the turbine, is running at a different speed within the hollow high-pressure compressor/turbine shaft, with each shaft having its own bearings. Both twin- and triple-spool engines have been
Gas turbines are composed of three main components: compressor, combustor, and power turbine. In the compressor section, the air is drawn in and compressed up to 30 times ambient pressure and directed to the combustor section, where fuel is introduced, ignited, and burned.
