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…

A Joule cycle is used for electricity production in a power plant. Air is introduced to the cycle from the ambient with a pressure of 1 bar, and a temperature of 20 °C. The air is compressed in compressor C1 and is thereafter cooled down to 30 °C. The air is compressed again in compressor C2. The air passes through a regenerator where it is heated by exhaust gases. Heat is added by combustion of fuel in combustion chamber CC1. The air is thereafter expanded in turbine T1. The air is reheated in combustion chamber CC2. The air is expanded in turbine T2, and the exhaust gases after the turbine pass through the regenerator and is finally vented to the ambient. Turbine T2 is driving compressor C2. The net work from the cycle is produced by the difference between the work produced by turbine T1 and compressor C1. The regenerator efficiency is 0.80, the isentropic efficiency of the compressor is 0.83, and for the turbine 0.85. The temperature after CC1 and CC2 is tCC, the pressure after…
