BRAYTON CYCLE The BRAYTON steps are as follows: Compression occurs between the intakeand the outlet of the compressor (Line AB). During this process, pressure andtemperature of the air increases. Combustion occurs in the combustionchamber where fuel and air are mixed toexplosive proportions and ignited. Theaddition of heat causes a sharp increasein volume (Line B-C). Expansion occurs as hot gas acceleratesfrom the combustion chamber. The gasesat constant pressure and increasedvolume enter the turbine and expandthrough it. The size of the passages isalso increased, which allows a furtherincrease in volume and a sharp decreasein pressure and temperature (Line C-D).

LM2500 GAS TURBINE GENERATOR SET . 1 . LM2500 Overview The LM2500 package was installed at Hitachi Zosen in Japan in 1994 and removed in 2011. It is a three piece split skid (generator, turbine & air intake), 50HZ. The package was only used for peaking power and after 15 years of operation only accumulated approximately 7,200 hours. The engine has been converted from a PH to a .
