Task: In a gas turbine, the compressor is two-part with intercooling. The LP compressor (before cooling) has a pressure ratio of 7/1 and the HP compressor (after cooling) has a pressure ratio of 4/1. The intercooler reduces the temperature by 200°C. The air has mass m 1 =200 kg/s with pressure p 1 = p 6 =1.01 bar and temperature t 1 = 20°C. The gas turbine's fuel is natural gas with a lower calorific value H LHV =40 MJ/kg and the temperature of the gas leaving the combustion chamber t 5 =1310°C. We can neglect pressure loss in the combustion chamber and sensible heat from the natural gas. Other data are: Data for air: L = 1 .4 & c p,L = 1.005 kJ / kgKData for the exhaust gas: AG = 1.333 & c p,AG = 1.15 kJ / kgKIsentropic efficiency LP compressor: η LPC,is = 0.84Isentropic efficiency HP compressor: η HPC,is = 0.86Isentropic efficiency of the expander: η E,is = 0.82Generator efficiency (incl. mech.): η G,GT = 0.97What is the pressure in the combustion chamber ?

Task:

In a gas turbine, the compressor is two-part with intercooling. The LP compressor (before cooling) has a pressure ratio of 7/1 and the HP compressor (after cooling) has a pressure ratio of 4/1. The intercooler reduces the temperature by 200°C. The air has mass m ₁=200 kg/s with pressure p ₁= p ₆=1.01 bar and temperature t ₁= 20°C. The gas turbine's fuel is natural gas with a lower calorific value H _LHV=40 MJ/kg and the temperature of the gas leaving the combustion chamber t ₅=1310°C. We can neglect pressure loss in the combustion chamber and sensible heat from the natural gas. Other data are:
