A steady-flow system operating on the ideal Ericsson cycle can achieve the Carnot efficiency. One of the salient features of this cycle is the isothermal expansion through a heated turbine, as shown in Fig. a. Heat is added to the turbine such that the outlet temperature is equal to the inlet temperature, i.e. T₁=T₂, and the overall pressure ratio for this process is rₚ=P₁/P₂. However, an isothermal expansion through a heated turbine is very difficult to achieve in practical engineering applications. An alternate approach is two use a multi-stage expansion process with reheating. In this approach, the gas expansion process is carried out in multiple stages with reheating in between each stage. Consider the two-stage turbine expansion with reheating shown in Fig. b. The gas enters the first stage of the turbine at state A1, is expanded isentropically to an intermediate pressure Pₐ₂, is reheated at constant pressure to state B1, and is expanded in the second stage isentropically to the…
On my online homework, it says the answer for part b, 993.2 kW and part c, 360.06 are incorrect. I also need help with part d. The figure below provides steady-state operating data for a cogeneration cycle that generates electricity and provides heat for campus buildings. Steam at 1.5 MPa, 280°C, enters a two-stage turbine with a mass flow rate of m1 = 2 kg/s. A fraction of the total flow, y = 0.15, is extracted between the two stages at 0.2 MPa to provide for building heating, and the remainder expands through the second stage to the condenser pressure of 0.1 bar. Condensate returns from the campus buildings at 0.1 MPa, 60°C and passes through a trap into the condenser, where it is reunited with the main feedwater flow. Saturated liquid leaves the condenser at 0.1 bar.
Assume 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 100F 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…
