CPC-GTC is the … Webb22 juni 2024 · In most designs, the pressure ratio of gas turbines ranges from about 11 to 16. The actual gas-turbine cycle is different from the ideal Brayton cycle since there are irreversibilities.
WebbTranscribed Image Text: Q11/ The gas-turbine portion 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 combustion chamber. The combustion gases leaving the gas turbine are used to heat the steam to 400°C at 10 MPa in a heat exchanger. WebbAir enters the compressor of a gas-turbine power plant, at 290 K; 0:1 MPa. The ratio of the maximum to minimum pressure in the cycle is 4:0 and the maximum cycle temperature is 1200 K. Compressor and turbine isentropic efficiencies are 0:85. The compression process occurs in two stages, each having a pressure ratio of 2:0 with intercooling to ...
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 … WebbThe power developed from the power turbine is dependent on the pressure ratio across the power turbine, which is determined by the gas generator performance and the power …
WebbThe thermodynamic cycle of the basic combined cycle consists of two power plant cycles. One is the Joule or Brayton cycle which is a gas turbine cycle and the other is the Rankine cycle which is a steam turbine cycle. The cycle 1-2-3-4-1 which is the gas turbine power plant cycle is the topping cycle. It depicts the heat and work transfer process taking …
