WebbHowever, there are practical limitations in increasing the pressure ratio. First, as you increase the pressure ratio, it increases the compressor exhaust temperature. This can result in the temperature of the gas leaving the combustion chamber exceeding the metallurgical limits of the turbine.

WebbThe gas turbine part of a combined gas-steam power plant has a pressure ratio of 16. Air enters the compressor at 300 K at a rate of 14 kg/s and is heated to 1500 K in the combustor. The combustion gases leaving the gas turbine flow thru a HRSG heat exchanger to heat the steam to 400 C at 10 MPa. The combustion gas leaves the HRSG … WebbThis compression ratio is dependent on the design. Gas turbines for power generation can be either industrial (heavy frame) or aeroderivative designs. Industrial gas turbines are designed for stationary applications and have …
WebbPressure ratio is the ratio of the compressor discharge pressure and the inlet air pressure. Aeroderivative engines are derived from jet engines, as the name implies, and operate at very high compression ratios (typically in excess of 30). Aeroderivative engines tend to be very compact and are useful where smaller power outputs are needed.
