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…
