Gas Turbinepressor Diagram. The brayton cycle describes the thermodynamics of a gas turbine engine and when describing the processes on a p v or t s diagram we denote the end of a process by using the station number. Also the pressure and temperature of fuel gas are monitored during normal operation of a gas turbine.
In addition the processes plotted on pv diagrams only work for a closed system in this case the ideal gas so there is no exchange of matter but still. The manufacturers need to know the details of fuel gas and only based on its characteristics they can guarantee the performance of their gas turbines. How a gas turbine works.
Air enters igvs inlet guide vanes which are not present on all gas turbines and passes through each of the stages on its way to the combustor section.
A simple layout is shown on fig. The cycle in block diagram form is shown on fig. The advantages of liquid fuels are easy handling less space for storage and injection of fuel is easily possible and can be controlled. The compressor of a gas turbine receives air at a pressure and temperature of 101 bar and 20c respectively and delivers it to the combustion chamber at a pressure and temperature of 404 bar and 200c respectively.
