Your selection was a gas-turbine power plant operating on an ideal Brayton cycle and according to the manufacturing datasheets it has the following specifications:
- A pressure ratio of 14.
- The gas temperature is 300 K at the compressor inlet and 1400 K at the turbine inlet.
- The mass flow rate of air is 0.783 kg/s
Under the assumption of standard air, perform the following:
1. The gas temperature of the compressor and the turbine exits,
2. Back-work ratio
3. Find the power output
4. Compare the power output of the basic Brayton cycle with the power output of the best modified Rankine cycle.
5. Compare the final efficiency of the basic Brayton cycle with those obtained from Project-1 for the modified Rankine cycle. How would you explain that the Brayton cycle is more preferred over the Rankin cycle in the power plant station?
For the gas turbine plant described in Task.1, investigate the principles of operation of a gas turbine plant by considering the following:
1. Construct TS and PV diagram
2. Construct simple sketches showing, all the competent for open and closed gas turbine engine
3. Describe the operating role of each component in the engine and the main difference between closed and open gas turbine engine
4. How would a closed gas turbine engine be combined with a steam power plant engine?

- For a Rankine cycle, increasing maximum temperature while holding all other parameters constant will allow an engineer to make the following statements Group of answer choices Quality at the turbine exit will decrease increasing liquid water content and causing turbine erosion. Quality at the turbine exit will increase and improve turbine durability. Increasing maximum temperature increases the average temperarture at which heat is added and will increase thermal efficiency Increasing maximum tempearture will decrease required mass flow rate for a specified power output.arrow_forwardAssume a basic (non-regenerative) ideal Brayton cycle where air modeled as IG with variables specific heat. The gas-turbine engine has the following operational parameters: Inlet Air Temperature:537 R Inlet Air Pressure:14.696 psia Compressor Pressure Ratio (rp):6.0 Firing Temperature:2400 R Heat Recovery Steam Generator: Assume that the exhaust from the gas turbine engine is directed to a heat recovery steam generator (HRSG)to produce wet steam (i.e. saturated vapor) at a pressure of 600 psia. Liquid water is supplied to the HRSG at 100F and 600 psia. The exhaust gas from the gas-turbine engine leaves the HRSG at the saturation temperature of the wet steam. With these conditions determine: a) the exit temperature of the wet steam (F), b) the intensive steam production rate, lbm-steam/lbm-exhaust gas. Absorption Chiller CHP: Assume the process steam from the HRSG is now used to drive an absorption chiller with COP of 0.7, and that the mechanical power of the gas-turbine engine is used…arrow_forward
